Wearables
What to evaluate when choosing a wearable that supports waterproofing for both pools and open water swims.
When selecting a waterproof wearable, consider water resistance ratings, real-world performance in pool versus open water, strap materials, fit, data tracking capabilities, battery life under continuous use, recovery after exposure, and practical everyday usability to ensure it survives chlorinated pools, saltwater, and fresh water during swims and daily activities.

When shopping for a wearable designed to withstand both pool and open water environments, the first aspect to assess is the water resistance standard it claims. Look for a published IP rating or an ATM (atmospheres) rating from a reputable manufacturer. An ideal device should comfortably handle at least 5 ATM or an IP68 rating, with explicit notes about submersion depths and durations. Real-world swimming, including surface swimming and occasional splashes, tests the device’s seals and gasket integrity. Vendors often differentiate between water resistance for rain or sweat and full submersion. Understanding these distinctions helps prevent premature wear or failure during a swim session.
Beyond the official rating, investigate how the device performs in actual swimming conditions. Pools introduce chlorine, which can affect sensors and buttons, while open-water environments involve salt exposure, varying temperatures, and waves. Look for user reviews and test results that mention long sessions, pool intervals with frequent immersions, and saltwater exposure without degradation. Check if the device maintains accurate heart rate, GPS, or pool swim metrics under these stressors. A robust waterproof wearable should show minimal performance drift after repeated submersions and still provide reliable readings once you exit the water and resume daily activities.
Consider build quality and material choices that withstand water and chlorine exposure.
Comfort matters as much as durability because a waterproof device should feel natural on the wrist for long swims and daily wear. Inspect the strap material and clasp, ensuring it won’t chafe, degrade, or retain water after immersion. Some silicones or elastomers retain salt or chlorine, requiring periodic cleaning with fresh water and mild soap. Pay attention to the ergonomics of the button layout or touch-sensitive controls because wet conditions can affect responsiveness. A well-designed wearable should offer easy access to essential features while you are swimming, without needing awkward hand movements or excessive manipulation. Comfort plus reliability equals consistent use.
Battery endurance is a practical concern when swimming outdoors or engaging in long pool sessions. A swim-focused wearable should deliver sufficient battery life for multi-day use or at least a full day of continuous swimming plus on-wrist activity tracking. Check how battery life changes with GPS, pulsometer, and display brightness enabled. Some devices conserve power by dimming the screen during athletic activity, which can reduce readability in bright sunlight. Also consider charging options that are convenient post-swim—magnetic or clip-in chargers are common, but ensure waterproof protection isn’t compromised during the charging process.
Performance metrics that matter for pool swimming and open-water tracking.
Build quality extends beyond the body’s waterproof seals. The glass or sapphire face should resist scratching from pool tiles or open-water debris, while the rear sensor housing must stay sealed after repeated beach or pool encounters. Inspect the case materials; marine-grade metals and corrosion-resistant plastics tend to hold up better over time. Be mindful of gasket design and the frequency of gasket replacement, which can affect long-term durability. Some brands offer extended warranties or service plans specifically for water exposure, giving you peace of mind. A sturdy chassis supports consistent performance across seasons and swimming environments.
Material selection for both swim and daily wear influences comfort, durability, and maintenance needs. Straps made from silicone, fluorinated rubber, or textured elastomer balance softness, stretch, and water shedding. They should dry quickly and resist salt or chlorine buildup. Look for removable straps that you can rinse after swimming and replace if discoloration occurs. The contact points between the sensor module and the strap should be reinforced to tolerate repeated dampness and movement. A thoughtfully engineered strap system reduces the risk of skin irritation and extends the life of the wearable in active water settings.
Daily usability and ecosystem compatibility for a water-portable wearable.
If you rely on built-in GPS for open-water distance and pacing, ensure the device has a reliable GPS receiver and fast cold-start capability. GPS performance can be hampered by dense foliage, buildings, or the open water’s reflective surface. Pairing with a supplementary accelerometer or gyroscope helps maintain pace and stroke counts when GPS signals are weak or momentarily lost. The device should also handle pool swim metrics, such as lap counting, stroke type detection, and turn detection, with minimal calibration. A well-rounded waterproof wearable delivers consistent data continuity whether you are sprinting in a lap pool or swimming long, choppy open-water miles.
Heart rate monitoring under water is a common feature but can be affected by immersion. Optical sensors should remain accurate enough to guide training rather than be treated as a precise medical device. Many wearables switch to a more conservative reading during high-intensity swimming to avoid excessive fluctuation. Check whether the unit supports HR zones, recovery insights, and VO2 max estimation in water. Some models store data locally while you’re out of range and sync when you reconnect, which is crucial for uninterrupted training logs. Ensure the health metrics align with your training goals and are consistent across swimming contexts.
Final considerations: brand support, warranties, and aftercare for water endurance.
A waterproof wearable should blend seamlessly into everyday life, not just the pool or shoreline. Evaluate the device’s user interface, readability in bright sun, and ease of accessing swim functions without wrestling with menus. The device should sync with a compatible mobile app or cloud service that can visualize swim routes, laps, and health trends. Data privacy and secure syncing are important, especially if the device holds sensitive health information. Check how often firmware updates arrive and whether they improve water performance or add new swim features. A strong software ecosystem extends the value of a waterproof wearable beyond the pool.
Battery management also matters when the device is used for extended open-water trips. Solar-assisted charging is rare but available on some models, while wireless charging offers convenience but can add water exposure risk during charging. Assess how the device behaves in cold water or wind-chill environments, as performance anomalies can occur with rapid temperature changes. It’s beneficial to have a power-saving mode that preserves essential swim metrics during long workouts. Consider whether the battery life aligns with your typical training schedule and travel plans.
When investing in a waterproof wearable, brand support plays a critical role in long-term reliability. Look for clear guidance on how to care for the seals, what cleaning routines are recommended, and how to handle salt or chlorine corrosion. A responsive customer service team can help diagnose moisture-related issues under warranty and advise on gasket replacements. Some manufacturers offer free inspections once a year or discounted service plans for water exposure. The value of a strong support network increases, especially if you rely on the device for critical training data or competitive swimming.
In the end, choosing a wearable that reliably survives pools and open water comes down to a balanced mix of tested waterproofing, durable materials, comfortable wear, dependable sensors, and a robust software ecosystem. Prioritize devices with transparent specs, user feedback from diverse environments, and clear maintenance guidelines. If possible, try a model in a store or borrow from a friend to assess comfort, control access when wet, and how well the app digest swim data. With careful evaluation, you’ll select a waterproof wearable that remains accurate, comfortable, and durable through countless laps, saltwater sessions, and daily use.
