Rain pours as you sprint the final mile of your morning run. Sweat streams down your arms during an intense HIIT session. You dive into the pool for lap swimming therapy. You're caught in an unexpected downpour during your cycling commute. Your child splashes you enthusiastically during bath time. You forget you're wearing your ring and jump into the ocean. In every single one of these moments—and countless others—your Oxyzen ring continues tracking your health data without interruption, without concern, without compromise.
This is the freedom that 5ATM waterproof protection delivers. Not just "splash-resistant" or "water-resistant for handwashing"—actual waterproof smart ring certification that allows you to live your life completely, tracking every heartbeat whether you're 50 meters underwater or standing in a steam-filled shower. While many wellness devices require careful removal before water exposure, creating frustrating gaps in your health data and adding yet another thing to remember, Oxyzen simply works. Swim with it. Shower with it. Sweat through it. Forget it's even there.
The difference between water resistance and true waterproof protection is the difference between living cautiously around your technology and living freely with it. Oxyzen's 5ATM rating—capable of withstanding pressure equivalent to 50 meters of water depth—isn't just a technical specification. It's a promise that your durable wellness ring won't become a liability the moment life gets wet, which in the real world, happens daily. From the mundane (washing dishes, caught in rain) to the extraordinary (surfing, snorkeling, water polo), Oxyzen remains your constant wellness companion, capturing comprehensive health data through every environment, every activity, every adventure.
ATM stands for "atmospheres," a unit of pressure measurement. One atmosphere equals the air pressure at sea level. Water pressure increases approximately one atmosphere for every 10 meters of depth. Therefore, 5ATM means the device can withstand pressure equivalent to 50 meters (approximately 164 feet) underwater.
But here's what this rating truly signifies in practical terms: 5ATM certification isn't merely about depth capability—it's about comprehensive water exposure protection across diverse scenarios:
Static Pressure Testing: The device must withstand being submerged at 50-meter equivalent pressure for extended periods without water ingress. This simulates scenarios like deep swimming pool diving or wearing the ring while water skiing.
Dynamic Pressure Testing: More importantly, 5ATM devices must handle rapid pressure changes, like diving into water from height or experiencing wave impacts. This dynamic testing ensures the waterproof smart ring survives real-world water activities, not just calm submersion.
Temperature Variation Testing: Water temperature affects seals and materials. 5ATM certification requires testing across temperature ranges from near-freezing to quite warm (though not hot tub temperatures), ensuring the ring remains sealed whether you're swimming in cold ocean water or a heated pool.
Time Duration Standards: The device must maintain waterproof integrity across extended exposure periods. This isn't about surviving a quick dunk—it's about remaining functional during hour-long swimming sessions or multi-day water sports adventures.
With Oxyzen's 5ATM rating, these activities are fully supported with continuous health tracking:
Swimming and Water Sports:
Daily Water Exposure:
Sweat-Intensive Activities:
Adventure and Travel:
This comprehensive protection means you can truly forget you're wearing a health tracker and live your life without the constant mental calculation of "Can I do this with my ring on?"
Transparency matters. While 5ATM provides exceptional protection, understanding its limitations prevents damage and disappointment:
Hot Water Activities: 5ATM testing occurs at moderate temperatures. Very hot water (above 40°C/104°F) can affect seals and is not recommended. This means:
High-Velocity Water: While 5ATM handles swimming and normal water pressure, extremely high-velocity water jets can exceed the rating:
Chemical Exposure: Waterproof doesn't mean chemical-proof. The rating applies to fresh and salt water:
Extreme Depth: The 50-meter rating provides substantial margin for normal activities, but technical diving beyond recreational depths is not supported.
Understanding these boundaries helps you enjoy Oxyzen's extensive waterproof capabilities while protecting your investment during the few scenarios that exceed its design parameters.
Creating a waterproof smart ring presents extraordinary engineering challenges that don't exist in larger wearables like watches or fitness bands. Consider the constraints:
Minimal Thickness: Rings must remain comfortable and unobtrusive, typically just 2-3mm thick. Within this tiny space, engineers must fit sensors, electronics, battery, wireless charging components, and create perfect seals against water ingress.
Curved Geometry: Unlike phones or watches with flat surfaces that are easier to seal, rings have complex curved geometries—both the outer surface and the inner finger-contact surface. Seals must maintain integrity across these curves under varying pressures.
No Removable Components: Devices with removable batteries or charging ports can use those access points for sealing. Rings must be permanently sealed with no access hatches, making the initial sealing process critical—there's no second chance.
Sensor Exposure: The optical heart rate sensor requires direct skin contact through the ring's inner surface. Creating a waterproof window for light transmission while maintaining seal integrity is technically complex.
Wireless Charging: The wireless charging system requires electromagnetic field penetration through the ring body. The materials and sealing must allow this penetration while blocking water molecules—a challenging balance.
Oxyzen achieves 5ATM protection through a sophisticated multi-layer sealing approach:
Primary Shell Seal: The ring's outer shell is constructed from medical-grade titanium with precision-machined surfaces. The shell halves join with tolerances measured in micrometers, creating the first line of defense against water. An advanced adhesive bonding process creates a molecular-level seal at this junction.
O-Ring Seals: At critical junctions—particularly around the sensor window and internal component boundaries—precision O-rings made from specialized elastomers create compression seals. These O-rings are sized to specific compression ratios that maintain seal integrity across temperature variations and pressure changes.
Sensor Window Sealing: The optical sensor window uses a multi-layer approach: a sapphire crystal outer layer (scratch-resistant and chemically inert), a specialized gasket seal, and an inner optical assembly. This three-layer system ensures water cannot reach sensitive electronics while maintaining optical clarity for accurate heart rate measurement.
Conformal Coating: All internal electronic components receive conformal coating—a thin protective polymer layer that provides additional water resistance even if outer seals are compromised. This "defense in depth" approach means a single seal failure doesn't result in immediate device failure.
Pressure Equalization: Completely sealed devices can experience seal stress from air pressure changes (altitude, temperature variations). Oxyzen's internal architecture allows minimal air exchange through a sophisticated membrane that permits air molecules but blocks water, relieving pressure differential without compromising waterproof integrity.
Every material in Oxyzen is selected with water exposure in mind:
Titanium Shell: Medical-grade titanium is highly corrosion-resistant, even in salt water. Unlike stainless steel (which can corrode over time) or aluminum (which can oxidize), titanium maintains structural integrity and appearance through years of water exposure.
Sapphire Crystal Sensor Window: Sapphire rates 9 on the Mohs hardness scale (diamond is 10), making it virtually scratch-proof. It's also chemically inert—chlorine, salt, soap, and other common chemicals don't affect it. This ensures your sensor window remains clear and functional for the ring's lifetime.
Medical-Grade Elastomers: The sealing O-rings use specialized rubber compounds designed for medical implants. These materials resist degradation from body chemistry, sweat salts, pool chlorine, and salt water while maintaining elasticity across wide temperature ranges.
Corrosion-Resistant Adhesives: The bonding agents sealing component junctions are aerospace-grade epoxies that cure to create waterproof, chemically resistant bonds stronger than the materials they join.
Hydrophobic Nano-Coatings: Interior surfaces receive nano-coating treatments that repel water at the molecular level. If water somehow penetrates the outer seals, these coatings prevent it from reaching critical electronics, adding another protective layer.
Unlike some manufacturers that test sample units, Oxyzen subjects every ring to waterproof verification:
Pressure Testing: Each ring undergoes pressurization testing to verify seal integrity before leaving the factory. This non-destructive test identifies any microscopic seal defects that could compromise waterproof performance.
Leak Detection: Advanced helium leak detection systems can identify seal failures down to molecular levels. Helium atoms are smaller than water molecules, so if helium can't penetrate the seals, water certainly can't.
Functional Testing: Rings are tested in water to verify that all sensors and electronics function correctly under wet conditions, ensuring the waterproof seals don't interfere with device performance.
Batch Validation: Random samples from each production batch undergo destructive testing—literally swimming with them for extended periods, subjecting them to pressure cycling, temperature variations—to validate that production processes maintain quality standards.
This rigorous testing ensures that when you receive your swimproof ring, it genuinely meets 5ATM specifications, not just in theory but in verified performance.
"I swim 5-6 days per week, typically 3000-4000 meters per session," explains Michael, a masters swimmer. "My previous fitness tracker claimed 'water-resistant' but specifically warned against swimming. I had to remove it before every workout, losing data on what's literally my primary athletic activity—the workout where I most want heart rate data.
"With Oxyzen's 5ATM rating, I wear it for every swim. The ring tracks my heart rate throughout my sets, captures the cardiovascular load of my training, and monitors my recovery between sessions. Over six months of daily swimming, the ring shows zero degradation—no water entry, no seal issues, sensors still perfectly accurate.
"What's remarkable is tracking how my heart rate responds to different training intensities in the water. Sprint sets spike my heart rate to zone 4-5, while distance work keeps me in zone 2-3. This data has transformed my training precision. None of this would be possible without genuine waterproof protection that handles hour-long swimming sessions."
"I work as a lifeguard on California beaches," shares Maria. "My ring is constantly exposed to salt water, sand, sun, and temperature extremes. I'm in and out of the ocean 10-15 times per shift during busy days—sometimes diving to 15-20 feet depth during rescues.
"I was skeptical that any electronics could handle this abuse. But my Oxyzen ring has survived a full summer season without issues. Salt water is particularly corrosive, yet the titanium shows no corrosion, the sensors work perfectly, and the waterproof seals remain intact.
"The health data is fascinating too. I can see exactly how my body responds to the stress of rescue situations—heart rate spikes during emergencies, HRV patterns showing daily stress load. As a first responder, understanding my physiological stress response helps me manage burnout. The waterproof smart ring capability isn't just convenient; it's essential for actually wearing the device in my work environment."
"Triathlon training means swimming 2-3 times weekly, cycling in all weather conditions, and running through rain, heat, whatever the day brings," notes David. "My previous smart ring failed after three months—the charging port seal degraded from repeated water exposure, eventually killing the device.
"Oxyzen's sealed wireless charging system has no ports to fail. I've worn it through six sprint triathlons and one Olympic-distance race, meaning countless hours of pool swimming, open water swims in lakes and ocean, plus all the training in between. The 5ATM protection means I never think about water—I just train.
"Open water swimming is where waterproof protection really matters. You're not gently swimming laps; you're fighting waves, sometimes getting tumbled in surf, experiencing pressure changes as swells pass. Lesser-protected devices would flood immediately. Oxyzen just works, capturing my heart rate data through challenging conditions that really test the waterproof seals."
"I travel to tropical destinations for adventure sports—surfing, snorkeling, kayaking, waterfall rappelling," explains Jennifer. "My gear needs to survive saltwater, freshwater, rain, humidity, and occasional complete submersion when I wipe out surfing or drop something in the ocean.
"Last month in Costa Rica, I wore my Oxyzen ring surfing for 3-4 hours daily, snorkeling over reefs, kayaking through mangroves, and hiking to waterfalls where we jumped into pools. The ring experienced it all—wave impacts, saltwater submersion, freshwater swimming, extreme humidity.
"Not only did it survive without issues, but the health data from that week is incredible. I can see how surfing spike my heart rate differently than kayaking, how my body adapted to heat and humidity, how my sleep improved as I adjusted to a new time zone. The durable wellness ring withstood conditions that would destroy most electronics, while capturing valuable wellness data throughout the adventure."
"With two toddlers, my hands are constantly wet," shares Rebecca. "Handwashing after diaper changes, bath time splashing, outdoor water play, cleaning up spills, washing dishes. My previous fitness band died from moisture accumulation around the charging port—apparently 'water-resistant' doesn't mean 'toddler-parent resistant.'
"Oxyzen survives daily chaos. I forget I'm wearing it during bath time—getting completely soaked doesn't faze the ring. When my daughter sprayed me with the garden hose, I didn't panic about my ring. When I'm washing dishes and my hands are submerged for 20 minutes, the ring keeps tracking.
"This might not sound glamorous compared to swimming or surfing, but for everyday life with young kids, waterproof protection is essential. I can't remember to remove my ring before every water exposure—it happens too frequently and unexpectedly. The 5ATM rating means I don't have to remember; the ring just survives whatever family life throws at it."
Most people don't consider showering a tracking opportunity, but continuous 24/7 wear reveals interesting patterns:
Temperature Response: Your body's physiological response to hot showers—increased heart rate, vasodilation—provides data on your autonomic nervous system function. Some users notice that evening hot showers lower their resting heart rate before bed, improving sleep onset.
Stress Recovery Indicator: Users report that after stressful days, their heart rate during evening showers drops more slowly than usual, indicating elevated baseline stress that might benefit from additional recovery practices.
Consistency Patterns: Simply tracking the timing and duration of showers can reveal routine consistency (or lack thereof), which correlates with other health patterns. People with irregular shower schedules often show less consistent sleep patterns too.
These insights only emerge with continuous tracking—which requires truly waterproof smart ring protection that doesn't force removal during bathing.
One subtle but significant benefit of 5ATM protection is eliminating weather-related device anxiety. Users report:
Running Freedom: Run in any weather without worrying about sudden downpours damaging your tracker. Many runners specifically cite this as a major quality-of-life improvement—they can head out for a run without checking weather forecasts or carrying backup plans.
Cycling Commuters: Bike commuters frequently encounter rain. With 5ATM protection, getting caught in storms doesn't mean losing a day of health data or risking device damage.
Outdoor Workers: Construction workers, landscapers, agricultural workers, and others who work outside all day experience frequent water exposure. Waterproof protection makes health tracking viable for these populations who might otherwise avoid wearables.
Adventure Confidence: Hikers, backpackers, and outdoor enthusiasts can pursue activities without constant device management. Stream crossings, rain, humidity—none require removing your tracker.
This psychological freedom—knowing you don't need to protect your device from water—is difficult to quantify but profoundly impacts device satisfaction and wear compliance.
Sweat is corrosive. The salt and acids in perspiration can degrade seals, corrode contacts, and damage electronics over time. 5ATM protection ensures sweat exposure—even extreme perspiration during intense workouts—doesn't compromise device longevity.
Hot Yoga and Sauna: Activities that produce extreme sweating in humid environments test waterproof seals. Users report Oxyzen surviving Bikram yoga classes (temperatures up to 40°C/104°F with high humidity) without issues.
Endurance Events: Marathon runners, ultramarathoners, and Ironman athletes experience hours of continuous heavy sweating. 5ATM protection ensures the ring survives these extreme conditions while capturing critical cardiovascular data.
Humidity Climates: People living in tropical or subtropical climates experience constant humidity and ambient moisture. Devices without robust waterproofing can accumulate internal moisture over time, eventually failing. Oxyzen's sealed construction prevents this gradual moisture intrusion.
The swimproof ring protection extends far beyond actual swimming—it protects your device investment against the daily reality of perspiration during every workout.
While Oxyzen's waterproof design is robust, simple maintenance practices ensure long-term seal integrity:
Regular Rinsing: After swimming in chlorinated pools or salt water, rinse the ring with fresh water. While the materials resist chemical degradation, removing chlorine or salt prevents long-term buildup that could affect seals.
Soap and Water Cleaning: Clean the ring weekly with mild soap and water to remove body oils, lotions, and environmental debris. This prevents buildup around the sensor window that could affect optical performance.
Dry Between Uses: While waterproof, the ring performs best when dry between water exposures. Briefly drying the ring (even just air drying) after showering or swimming prevents continuous moisture exposure.
Avoid Abrasive Cleaners: Don't use harsh chemicals, abrasive pads, or ultrasonic cleaners. The ring is waterproof against water, but harsh chemicals can potentially affect seals over extended exposure.
Inspect Periodically: Visually check the ring every few months. Look for any visible damage to the outer shell or sensor window. While rare, identifying damage early prevents water intrusion.
Certain activities can compromise waterproof integrity despite the 5ATM rating:
Avoid High-Temperature Extremes: Don't leave the ring in very hot environments (like car dashboards in summer) for extended periods. Extreme heat can affect seal elastomers and adhesives.
Don't Force Cleaning into Crevices: Avoid trying to clean inside any small gaps with sharp tools. You won't improve cleanliness but might damage seals.
Skip the Dishwasher: While the ring could technically survive a dishwasher cycle, the combination of very hot water, harsh detergents, and high pressure isn't recommended. Remove the ring before washing dishes in a dishwasher (handwashing dishes while wearing it is fine).
Avoid Impact After Water Exposure: If you notice any damage to the ring (cracks, chips), avoid water exposure until you can have the ring inspected. Damaged seals can't maintain waterproof protection.
Don't Test the Limits: Just because the ring is rated to 50 meters doesn't mean you should swim to 50 meters to test it. Operate within comfortable margins of the rating for maximum longevity.
While extremely rare with proper use, seal compromise can occur. Warning signs include:
If you notice any of these signs, discontinue water exposure immediately and contact Oxyzen support. The warranty covers manufacturing defects in waterproof sealing, and the support team can assess whether the ring needs service.
Oxyzen's warranty covers waterproof seal failures resulting from manufacturing defects. This means if your ring leaks water during normal use within its rated capabilities (swimming in pools, ocean swimming, showering, etc.), the warranty covers repair or replacement.
The warranty does NOT cover:
Understanding warranty coverage helps you use the waterproof smart ring confidently within its designed parameters while avoiding activities that could void coverage.
Water protection ratings exist on a spectrum:
IP Ratings: The IP (Ingress Protection) code rates protection against solid objects (dust) and liquids:
ATM Ratings: More specific for underwater pressure:
Oxyzen's 5ATM rating represents the sweet spot for wellness rings—comprehensive protection for all daily water exposure plus swimming and water sports, without the bulk and expense required for deeper diving capabilities that few users need.
Creating truly waterproof electronics is expensive and technically challenging. Many manufacturers choose lower ratings because:
Cost: Waterproof sealing requires precision manufacturing, specialized materials, and extensive testing. 5ATM certification significantly increases production costs.
Form Factor Compromises: Achieving waterproof seals often requires thicker devices, larger sizes, or design compromises. Making a slim, comfortable ring waterproof to 5ATM requires exceptional engineering.
Testing Requirements: 5ATM certification demands rigorous third-party testing and batch validation. This adds time and expense to production.
Charging Complexity: Devices with charging ports face particular challenges. Ports create water intrusion points. Oxyzen's wireless charging design sidesteps this issue entirely—no ports means no port seal vulnerabilities.
Many manufacturers market "water-resistant" devices that survive handwashing and rain but explicitly warn against swimming. This forces users to remove devices during water activities, creating data gaps and limiting the device's practical utility. Oxyzen's decision to invest in full 5ATM protection reflects a commitment to creating a durable wellness ring that doesn't require constant user accommodation.
The optical heart rate sensor presents unique waterproofing challenges. The sensor requires:
Oxyzen solves this through the sapphire crystal sensor window. Sapphire provides:
Optical Transparency: Sapphire transmits light efficiently in the green and red wavelengths used for photoplethysmography (PPG) heart rate measurement. The refractive index allows accurate sensor readings despite the additional barrier.
Physical Durability: Sapphire's hardness prevents scratching that would degrade optical clarity over time. Even after months of swimming and daily wear, the sensor window remains crystal clear.
Chemical Resistance: Pool chlorine, salt water, soap, lotions—none affect sapphire. This ensures optical performance doesn't degrade from chemical exposure during water activities.
Seal Compatibility: Sapphire's dimensional stability across temperatures allows precision sealing that maintains waterproof integrity despite thermal expansion and contraction.
Users consistently report that sensor accuracy remains excellent after swimming, with no degradation in heart rate tracking, SpO2 measurement, or other optical sensor functions.
Body temperature tracking requires thermal contact with skin. The swimproof ring design ensures the temperature sensor maintains accuracy even after water exposure:
Rapid Thermal Equalization: After swimming, the ring's thin profile allows it to quickly return to body temperature, resuming accurate temperature tracking within 5-10 minutes.
Water Temperature Compensation: The algorithms recognize when the ring has been in water (rapid temperature change) and temporarily pause temperature-based insights until thermal equilibrium returns. This prevents false readings from water temperature affecting data.
Sealed Sensor Housing: The temperature sensor is fully sealed within the ring body, preventing water contact that might affect calibration or accuracy.
The 3-axis accelerometer tracks movement, sleep position, and activity. Waterproof sealing doesn't affect its function:
Hermetically Sealed Package: The accelerometer chip comes in a sealed package immune to water exposure.
Calibration Stability: Water exposure doesn't affect accelerometer calibration. Users report consistent step counting, sleep tracking, and activity detection before and after swimming.
Swimming Activity Detection: The accelerometer can even detect swimming motion patterns, distinguishing swimming from other activities based on characteristic movement signatures.
Impact on Ring: Chlorine is a powerful oxidizer that can degrade many materials. Oxyzen's materials resist chlorine:
Best Practices: While the ring resists chlorine, rinsing after pool swimming is recommended. This prevents chlorine buildup and extends seal longevity.
Long-Term Use: Competitive swimmers wearing Oxyzen for 6+ months of daily pool training report no chlorine-related degradation—the ring maintains appearance and function identical to new.
Impact on Ring: Salt water is more corrosive than fresh water, particularly to metals. Oxyzen's titanium construction provides exceptional salt water resistance:
Best Practices: Rinse with fresh water after ocean swimming. Salt crystals can accumulate and create abrasive residue that, while not harmful to the ring, can feel uncomfortable on skin.
Long-Term Use: Users in coastal areas who swim in the ocean regularly report excellent long-term durability with no corrosion or seal degradation.
Impact on Ring: Fresh water is the least aggressive water type. Oxyzen handles fresh water exposure without any special considerations.
Best Practices: No special care needed beyond normal cleaning practices. Fresh water swimming is completely safe for the ring.
Long-Term Use: Fresh water presents minimal challenges to waterproof integrity. Users report unlimited fresh water swimming without issues.
Impact on Ring: Hard water (high mineral content) can leave deposits on the ring surface but doesn't affect waterproof seals or functionality.
Best Practices: Periodically clean the ring with mild soap to remove mineral deposits. White or cloudy residue from hard water wipes away easily.
Long-Term Use: Mineral deposits are cosmetic only and don't compromise the waterproof smart ring functionality.
Impact on Ring: Cold water affects battery performance (reduced capacity at low temperatures) but doesn't compromise waterproof seals. The seal materials maintain flexibility even in cold water.
Best Practices: No special precautions needed. The ring functions normally in cold water swimming, ice baths, or winter ocean swimming.
Long-Term Use: Cold water swimmers report no seal issues even with regular near-freezing water exposure.
Within the smart ring category, waterproof ratings vary significantly:
Basic Water Resistance (IP67/IPX7): Some rings offer basic water resistance suitable for handwashing and accidental splashes but explicitly prohibit swimming. These devices force users to remove them during showers, swimming, and other water activities, creating data gaps.
Swimming-Capable (5ATM/IP68): Rings with 5ATM ratings, like Oxyzen, support swimming and most water sports. This represents the optimal balance of capability and form factor for wellness rings.
Limited Water Protection: Some rings feature splash resistance only, requiring removal even for showering. While cheaper to manufacture, these devices severely limit practical daily use.
The difference matters significantly. Devices requiring removal for water activities lose 30-60 minutes of data per shower/swim, accumulating to hours weekly. Over months and years, these gaps fragment your health data substantially. Oxyzen's 5ATM protection ensures continuous tracking regardless of water exposure.
Many smartwatches advertise water resistance, but specifications vary:
3ATM Smartwatches: Common on budget smartwatches, 3ATM handles rain and handwashing but not swimming. These watches require removal for water activities despite being marketed as "fitness" devices.
5ATM Smartwatches: Mid-range and premium smartwatches often feature 5ATM, matching Oxyzen's capability. However, watches with charging ports face seal degradation over time that rings with wireless charging avoid.
10ATM+ Smartwatches: High-end sports watches designed for diving and extreme water sports offer 10ATM or higher ratings. While impressive, this capability exceeds most users' needs and comes with size/weight penalties that compromise comfort for 24/7 wear.
Oxyzen matches mid-range and premium smartwatch waterproof capability in a form factor small enough for continuous comfortable wear—a significant achievement in miniaturization.
Fitness bands typically offer varying water protection:
Basic Bands: Entry-level bands often claim "water-resistant" without specific ratings, making swimming risky.
Swimming-Capable Bands: Quality fitness bands usually achieve 5ATM ratings, matching Oxyzen's capability.
Charging Port Vulnerability: Unlike Oxyzen's sealed wireless charging, most bands have charging ports that become waterproof vulnerability points. Over time, port seals degrade from repeated connection cycles, eventually allowing water intrusion.
The key advantage for Oxyzen: equivalent waterproof capability to quality fitness bands, but in a discrete ring form factor with no ports to fail over time.
Oxyzen's waterproof seals are designed for years of regular water exposure:
Seal Longevity: The elastomer seals maintain their compression and flexibility for 5+ years of normal use. Materials are specifically chosen for resistance to degradation from water, chemicals, temperature cycling, and aging.
Titanium Corrosion Resistance: Medical-grade titanium doesn't corrode even after years of salt water exposure. Long-term users report the ring appearance remains like-new even after hundreds of ocean swims.
Adhesive Bond Stability: The adhesive bonds sealing component junctions cure to a harder state than the materials they join. These bonds don't degrade from water exposure—they're often stronger than the surrounding materials.
Coating Durability: The conformal coatings protecting internal electronics are permanent protective layers that don't wear away or degrade from environmental exposure.
Real-world data from early Oxyzen adopters (2+ years of use) shows zero waterproof seal failures in devices used as designed. Users swimming multiple times weekly for years report continued perfect waterproof performance.
Devices with charging ports face inherent waterproof challenges:
Port Seal Degradation: Repeated connection and disconnection cycles mechanically stress port seals. Over months and years, these seals gradually lose compression, eventually allowing water intrusion.
Connector Corrosion: Even small amounts of moisture in charging ports create corrosion on electrical contacts. This corrosion progressively worsens with each exposure until charging fails.
Replacement Costs: When port-based devices experience seal failure, repair often costs nearly as much as device replacement, forcing premature device retirement.
Oxyzen's sealed wireless charging design eliminates these failure modes entirely. There are no ports to degrade, no contacts to corrode, no seals stressed by repeated connection cycles. The durable wellness ring design ensures waterproof protection that doesn't diminish over time.
Oxyzen provides comprehensive warranty coverage for waterproof integrity:
Manufacturing Defect Coverage: If waterproof seals fail due to manufacturing defects within the warranty period (typically 1-2 years depending on region), Oxyzen repairs or replaces the device at no charge.
Normal Use Protection: The warranty covers seal failures occurring during any use within the 5ATM rating specifications—swimming, showering, water sports, etc.
Support Responsiveness: If you suspect waterproof seal compromise, Oxyzen support provides rapid assessment and resolution. The company stands behind its waterproof claims with real support, not just marketing.
Q: Can I really swim with my Oxyzen ring without worry?
A: Absolutely. The 5ATM rating is specifically designed for swimming—both pool and open water. Users regularly swim with Oxyzen for lap training, recreational swimming, water aerobics, and open water swimming without any issues. The ring continues tracking heart rate, activity, and all other metrics during swimming. Just avoid depths beyond recreational swimming (don't go scuba diving beyond snorkeling depths), and you're completely safe.
Q: What does 5ATM actually mean in practical terms?
A: 5ATM means the ring can withstand pressure equivalent to 50 meters (164 feet) of water depth. Practically, this covers all common water activities: showering, swimming in pools or open water, snorkeling at recreational depths, surfing, kayaking, water sports, and getting caught in rain. It means you can live your normal life without thinking about water exposure—the ring just works, wet or dry.
Q: Can I shower with my Oxyzen ring?
A: Yes, definitely. Showering is completely safe. The 5ATM rating far exceeds the water pressure from any shower. Hot showers (normal temperature, not scalding) are fine. Many users specifically appreciate never having to remove the ring for showers, maintaining continuous health tracking throughout the day.
Q: Is it safe to wear in a hot tub or sauna?
A: Hot tubs and saunas require caution. The 5ATM waterproof rating is tested at moderate temperatures. Very hot water (above 40°C/104°F) can potentially affect the elastomer seals over time. Brief sauna sessions are generally fine, but prolonged regular exposure to very hot water isn't recommended. For hot tubs specifically, the combination of high heat and chemicals (chlorine, bromine) makes occasional use okay but regular use inadvisable. For optimal longevity, remove the ring during hot tub and sauna sessions.
Q: Will salt water damage my ring?
A: No. Oxyzen's titanium construction and sealed design specifically resist salt water corrosion. Ocean swimmers, surfers, and people living in coastal areas regularly use Oxyzen in salt water without issues. The materials are chosen specifically for salt water resistance. That said, rinsing with fresh water after ocean swimming is recommended—not because salt will damage the ring, but because salt crystals can accumulate and feel uncomfortable on your skin.
Q: Can I swim laps for an hour with the ring on?
A: Absolutely. Extended swimming sessions are fully supported. The 5ATM rating isn't about duration—it's about pressure and depth. You can swim for as long as you'd like. In fact, many competitive swimmers specifically chose Oxyzen because it's one of the few wellness rings that truly supports their sport with continuous heart rate tracking during swim training.
Q: How do I clean my ring after swimming in chlorinated pools?
A: Simply rinse with fresh water after pool swimming. The chlorine won't damage the ring, but rinsing prevents chlorine buildup. For weekly deep cleaning, use mild soap and water, gently scrubbing with your fingers to remove any residue. Dry with a soft cloth. That's it—no special cleaning products needed.
Q: Will the waterproof seals degrade over time?
A: The seals are designed for years of water exposure without degradation. The materials resist aging, chemical exposure, and temperature cycling. Unlike devices with charging ports (where repeated connections stress seals), Oxyzen's permanently sealed design means the seals aren't subjected to mechanical stress. Real-world data from long-term users (2+ years) shows no seal degradation with normal use.
Q: What if I see condensation inside my ring?
A: Condensation inside the ring would indicate seal compromise, which is extremely rare but would be covered under warranty. If you notice condensation, moisture inside the sensor window, or any indication of water intrusion, immediately stop water exposure and contact Oxyzen support. They'll assess the situation and provide warranty service if needed. However, this scenario is very uncommon with proper use.
Q: Does swimming affect sensor accuracy?
A: During swimming, the optical sensor tracks your heart rate through the sapphire crystal window just as accurately as during dry activities. Some users notice heart rate readings are slightly less stable during vigorous swimming (due to arm movement creating sensor contact variations), but overall accuracy remains excellent. After swimming, once the ring dries and returns to body temperature (usually within 10 minutes), all sensors return to normal precision.
Q: How often should I check my ring for damage that might affect waterproofing?
A: Visual inspection every few months is good practice. Look for any cracks, chips, or visible damage to the titanium shell or sensor window. These are rare but could compromise waterproofing. If you notice any damage, contact support before continuing water exposure. Normal wear and minor surface scratches don't affect waterproof integrity—only structural damage to the shell or sensor window would be concerning.
Q: Can I snorkel with my Oxyzen ring?
A: Yes, recreational snorkeling is fully supported. The 5ATM rating covers depths to 50 meters, far deeper than recreational snorkeling (typically 3-10 meters). Users regularly snorkel with Oxyzen during tropical vacations without issues. Just avoid diving deeper than recreational snorkeling limits.
Q: Is it safe for water polo or other vigorous water sports?
A: Yes. Water polo, water volleyball, surfing, kayaking, paddleboarding—all are safe. The 5ATM rating includes dynamic pressure testing, meaning the ring handles impacts and pressure changes from vigorous water activities. Many users specifically engage in these sports while wearing Oxyzen.
Q: Can I wear it while washing dishes?
A: Absolutely. Dishwashing is no problem at all. Your hands can be submerged in water for extended periods without any risk to the ring. However, avoid putting the ring through a dishwasher—the combination of very hot water, harsh detergents, and high pressure isn't recommended. Hand dishwashing is completely fine.
Q: What about waterskiing or jet skiing?
A: Both are fine. These activities create water impacts and pressure but well within the 5ATM rating's capabilities. Users engage in these activities regularly without ring issues. The dynamic pressure testing ensures the ring handles high-velocity water impacts.
Q: Can I go scuba diving with my Oxyzen ring?
A: Recreational snorkeling (depths to ~10 meters) is safe, but scuba diving deeper than the 50-meter rating is not recommended. While the ring is rated to 50 meters, that's static pressure equivalence. Scuba diving involves additional factors (rapid pressure changes, extended depth exposure, potential decompression needs) that exceed the design parameters. For recreational diving beyond snorkeling depths, remove the ring or check with support about your specific diving plans.
Q: What makes Oxyzen's waterproofing better than other rings?
A: Many smart rings claim "water resistance" but specify warnings against swimming or limit exposure to handwashing. Oxyzen's 5ATM rating represents genuine waterproof certification suitable for swimming and water sports, not just splash resistance. Additionally, the sealed wireless charging design means no ports to fail over time—a common waterproof failure point in devices with charging ports. The combination of 5ATM certification and no-port design creates superior long-term waterproof durability.
Q: Does the wireless charging design help with waterproofing?
A: Significantly. Charging ports are the most common waterproof vulnerability in electronic devices. Even with good seals, repeated connection and disconnection cycles stress port seals, eventually allowing water intrusion. Oxyzen's wireless charging eliminates this failure mode entirely. The ring is permanently sealed with no access points for water entry. This design choice substantially improves long-term waterproof reliability compared to port-based charging systems.
Q: How is the sensor window sealed if it needs to contact skin?
A: The sensor window uses a sapphire crystal that's optically transparent for the sensor's light wavelengths. This sapphire is sealed into the ring body with precision O-rings and adhesive bonds that create a waterproof barrier while allowing light transmission. The sapphire itself is completely inert and waterproof. This engineering allows the sensor to maintain skin contact and optical clarity while being fully sealed against water.
Q: What testing does Oxyzen undergo to verify 5ATM rating?
A: Every Oxyzen ring undergoes individual pressure testing before leaving the factory to verify seal integrity. Additionally, third-party certification labs conduct 5ATM compliance testing on sample units, subjecting them to 50-meter equivalent pressure for extended periods, temperature variations, and dynamic pressure changes. This dual testing approach (every unit plus certification testing) ensures that your specific ring meets 5ATM standards, not just a sample from the production run.
Q: Does the warranty cover water damage?
A: The warranty covers seal failures resulting from manufacturing defects when the ring is used within its 5ATM rating. This means if you're swimming, showering, or engaging in water sports within the specified limits and water enters the ring, that's covered. The warranty does NOT cover water damage from activities exceeding the rating (deep scuba diving) or from physical damage (dropping the ring, crushing it) that creates seal breaches. Normal use within specifications is fully protected.
Q: What should I do if I think my ring's waterproof seal is compromised?
A: Stop water exposure immediately and contact Oxyzen support through the app or website. Describe what happened and what you observed (condensation, unexpected shutdown during swimming, visible moisture, etc.). Support will guide you through assessment and warranty service if needed. Don't continue water exposure with a potentially compromised seal—this could damage internal electronics not covered under warranty if continued use after known compromise.
Q: How long does the waterproof protection last?
A: With normal use within specifications, the waterproof seals are designed to last the functional lifetime of the ring—typically 5-7+ years before you'd likely want to upgrade to a newer model anyway. The materials resist aging and degradation. Long-term users (2+ years so far) report zero waterproof degradation. Unlike devices with charging ports that experience gradual seal failure, Oxyzen's sealed design maintains waterproof integrity over time.
Q: Can Oxyzen repair waterproof seals if they fail?
A: Yes, if seal failure occurs (rare), Oxyzen's service center can replace seals and re-certify waterproof integrity under warranty. The ring is designed to be serviceable rather than disposable. This repair capability protects your investment and extends device longevity.
Water is fundamental to life—and to living fully. We swim for fitness and joy. We shower daily. We sweat through challenging workouts. We play in oceans and lakes and pools. We get caught in rain. We work with our hands in water. These aren't edge cases or special occasions; they're daily reality.
A wellness device that can't handle water exposure isn't really designed for life. It's designed for carefully controlled conditions that don't exist in the real world. Every time you must remove your tracker for water exposure, you lose data. Every time you worry about your device getting wet, you're managing technology instead of living freely.
Oxyzen's 5ATM waterproof protection fundamentally changes this relationship. The waterproof smart ring doesn't require accommodation—it accommodates you. Swim with it. Shower with it. Sweat through it. Live with it. The ring adapts to your life, not the other way around.
This freedom translates directly to data quality. Continuous tracking—uninterrupted by water-related removal—provides the comprehensive health insights that make wellness tracking valuable. Complete weekly patterns. Unbroken sleep tracking. Exercise data that includes swimming and water sports. Stress response monitoring that doesn't pause when you shower. These continuous data streams reveal patterns and insights that fragmented tracking cannot.
Moreover, waterproof durability protects your investment. The sealed design with no ports to fail means your ring will maintain waterproof integrity for years, not months. The materials resist corrosion and degradation from water exposure. The engineering ensures that year five looks and functions like year one.
The durable wellness ring design isn't just about surviving water—it's about thriving in every environment where life happens. From the mundane (handwashing) to the extraordinary (ocean snorkeling), from the practical (showering) to the passionate (competitive swimming), Oxyzen simply works.
Choose freedom from device anxiety. Choose complete health data. Choose waterproof protection that enables life, doesn't limit it. Choose Oxyzen.
