Determining whether the Apple Watch 3 is waterproof requires a closer look at its specific engineering and the official ratings provided by Apple. While the device is designed to handle everyday encounters with water, such as rain or hand washing, it is not intended for deep water activities like high-velocity watersports or extended submersion. Understanding the distinction between water resistance and complete waterproofing is essential for setting proper expectations and ensuring the longevity of your device.
Understanding the IP68 Rating
The primary technical specification that defines the water resistance of the Apple Watch 3 is its Ingress Protection (IP) rating. Specifically, the first generation of the Apple Watch 3, released in September 2017, holds an IP68 rating under IEC standard 60529. This rating signifies that the device is dust-tight and can withstand immersion in water beyond 1 meter. However, the official Apple documentation specifies a depth of 50 meters, which aligns with the WR50 rating often seen on other sports watches.
What IP68 Means in Practical Terms
An IP68 rating indicates that the Apple Watch 3 is protected against dust ingress and can be submerged in fresh or salt water up to 50 meters (approximately 164 feet) for up to 30 minutes. This level of protection is sufficient for accidental drops into water, showering, and swimming in a pool or the ocean. It is important to note that this rating is based on laboratory conditions and does not account for the effects of wear and tear, such as seal degradation over time, which can compromise the integrity of the device.
Water Lock Feature and Usage
To optimize the water resistance of the Apple Watch 3, Apple includes a specific feature known as Water Lock. This mode, activated through the Control Center, disables the touchscreen and the haptic feedback of the crown to prevent accidental inputs while the watch is submerged. Before swimming or showering, users are advised to engage this feature to ensure the touch interface remains responsive when the watch is dried off.
Best Practices for Maintenance
Even with a robust IP68 rating, proper care is necessary to maintain the water resistance of the Apple Watch 3. Exposure to soaps, shampoos, lotions, and perfumes can break down the seals that keep water out, potentially causing damage over time. Additionally, the watch should be dried thoroughly after exposure to chlorine or salt water, as these substances can be corrosive to the internal components and the exterior casing.
Limitations and Activities to Avoid Limitations and Activities to Avoid
Despite the high IP68 rating, there are specific activities that the Apple Watch 3 is not designed to handle. High-velocity water sports, such as water skiing, jet skiing, or diving, expose the device to forces and pressures that exceed its design limits. The turbulence and rapid changes in pressure associated with these activities can force water into the case, bypassing the protective seals and leading to malfunction or damage.
Avoid hot tubs, saunas, and steam rooms, as the high temperatures can degrade the seals.
Keep the device away from soaps, shampoos, and lotions.
Do not expose the watch to pressurized water sources, like a shower or faucet stream.
Rinse the device with fresh water after exposure to salt water or chlorine.
Comparison with Later Models
When evaluating the Apple Watch 3 in the current market, it is helpful to compare its water resistance to newer models. The Apple Watch Series 2 introduced a swim-proof design with a 50-meter water resistance rating and additional features like a water ejection system. While the Apple Watch 3 shares the same 50-meter rating, later models like the Series 7 and Series 8 offer improved durability and faster charging times, making them more suitable for rigorous aquatic activities.
