Beyond the Splash: Navigating the Complex World of Waterproof Wearables for Swimmers

The Misunderstood Language of Water Resistance
For the average consumer, the term ‘waterproof’ is often used as a catch-all. In the world of wearables, however, that terminology is a legal minefield. Most manufacturers prefer ‘water-resistant,’ a distinction that matters the moment you dive into a pool. The difference between a device that survives a rainstorm and one that survives a 50-meter freestyle sprint comes down to two competing standards: Ingress Protection (IP) and Atmosphere (ATM) ratings.
IP ratings, specifically the second digit (e.g., IPX8), measure how well a device keeps out particles and liquids under specific, often static, conditions. ATM ratings, however, measure pressure. A 5ATM rating means the device can theoretically withstand the pressure of 50 meters of static water. For swimmers, 5ATM or IPX8 is the baseline; anything less risks permanent hardware failure due to the dynamic pressure created by moving through water.
It is also worth noting that water resistance is not a permanent state. Gaskets perish and seals degrade over time, meaning a watch that was dive-ready three years ago may now be a liability in a lap pool.
The Specialized Contenders: From AR Goggles to Dive Computers
While smartwatches dominate the wrist, the Form Smart Swim 2 represents a shift toward purpose-built aquatic hardware. Rather than checking a wrist-mounted screen—which disrupts stroke mechanics—Form integrates an augmented reality (AR) display directly into the goggles’ lenses. Users see real-time metrics like stroke pace and distance projected in their field of vision.
The inclusion of SwimStraight technology, a digital compass for open-water navigation, solves a perennial problem for marathon swimmers who struggle to maintain a straight line. However, the hardware isn’t without trade-offs. The overlay can be distracting for some, and the lack of prescription options makes them a non-starter for a significant portion of the swimming population.
For those who prioritize data integrity and durability, Garmin remains the industry standard. While many Garmin models are water-resistant, the Descent G2 is a powerhouse, rated at 10ATM (100 meters). The critical edge here is Garmin’s use of leakproof inductive buttons, which prevent water ingress during underwater actuation—a common failure point in cheaper wearables. The G2’s ability to automatically detect stroke type (freestyle, breaststroke, backstroke, or butterfly) makes it an essential tool for competitive athletes tracking efficiency and volume.
The Ecosystem Play: Apple and Google
For users deeply embedded in the iOS ecosystem, the Apple Watch Ultra 3 is the only logical choice for serious swimming. While the standard Series and SE models are sufficient for casual pool laps, the Ultra 3 is engineered for higher pressures, boasting a 100m water resistance rating and official approval for snorkeling and diving up to 40m. Its satellite communication capabilities provide a critical safety layer for open-water swimmers who venture beyond the reach of cellular towers.
On the more accessible end of the spectrum, the Fitbit Charge 6 caters to those who want a fitness tracker rather than a full-fledged computer on their wrist. With a 5ATM rating and a dedicated Water Lock feature to prevent accidental touch-screen activations, it handles the basics of lap counting and heart rate monitoring efficiently. However, the user experience has been marred by Google’s recent overhaul of the Fitbit app into ‘Google Health.’ Users have reported frustration with the new AI-driven coaching summaries, which some argue obfuscate raw data in favor of algorithmic interpretations.
