Apple Watch has been a leader in smartwatches for years. They are popular not only for their design and unique features, but also for their versatile usability. However, there are limits to consider in everyday activities. What is their water resistance and heat resistance?
While the newest Apple Watch series have excellent resistance to the elements, the older ones are a little more sensitive. So here's a brief overview of what you can do with each version and, conversely, which factors you should avoid.
The first and second generations of Apple Watch (Series 0 and Series 1) are IPX7 water-resistant. Thus, it can handle rain or splashes of water without problems, but submersion below the surface can cause damage. As such, these versions are not designed for swimming. Apple Watch Series 2 and all newer versions already feature ISO 22810:2010 water resistance. In practice, this means they can be submerged up to 50 meters below the surface of the water. This makes them suitable for swimming. However, Apple does not recommend wearing them when diving to great depths.
Beware of strong water currents with Apple Watch Series Zero and Series One, as well as newer models. For example, from pressure washers or when water skiing. These can often draw pressure higher than that at a depth of 50 meters below the surface. Thus, they can cause damage.
You can shower with Apple Watch, but the manufacturer does not recommend exposing it to shampoo, shower gel, and similar hygiene products. The chemical ingredients can adversely affect seals or other sensitive components.
Apple Watch Series 2 and above can also be used in seawater. However, it's important to rinse them thoroughly with fresh water afterwards. Otherwise, salt crystals can block the microphone or other small holes and interfere with functionality.
Handy tip: Always activate "Water Lock" when using Apple Watch in water. This is a screen lock to prevent unwanted activation of various functions in water.
Keep in mind that not all Apple Watch bands are waterproof. In particular, leather and steel versions are not designed for prolonged exposure to water.
Apple Watch's heat resistance is a separate chapter. The manufacturer claims that it works best in the thermal range of 0 - 35 °C. Skiing with Apple Watch is possible, but it is not recommended to use it in temperatures well below 0 °C. Prolonged exposure to freezing temperatures causes faster battery degradation.
Wearing Apple Watch on sunny summer days usually doesn't cause any problems. However, avoid prolonged exposure to direct sunlight, such as when sunbathing. It is also not advisable to wear the Watch in a sauna.
Our tip: If your Apple Watch overheats, it will automatically lock and a thermometer symbol will appear on the display. If this happens, take it off your wrist and place it in a well-ventilated, shaded area where it will cool down naturally.
If your Apple Watch smartwatch stops working completely or can't run certain functions, it's usually possible to fix it. However, there can be many causes of problems. That's why it's a good idea to leave it in the hands of the experts.
