The Apple Watch Series 9 is a commendable companion for shallow aquatic adventures, thanks to its WR50 water resistance rating under ISO standard 22810:2010. However, it's pivotal to understand the restrictions to ensure the longevity of your device.
The Series 9's water resistance is further enhanced by its choice of materials. While the specifics may vary, the tradition of utilizing robust materials like Ion-X glass or sapphire crystal glass for enhanced durability and scratch resistance, as seen in Series 8, may continue. These materials not only offer superior protection against everyday wear but also contribute to the device's water resistance capability.
One of the ingenious features contributing to the Series 9's water resistance is its speaker design. Unlike conventional designs, the speaker on the Apple Watch Series 9 is engineered to expel water using sound vibrations once it comes into contact with moisture
Water Resistance Explained
The WR50 rating signifies that the device can be submerged up to 50 meters under specific conditions, but it's not designed for all aquatic environments. Activities involving high-velocity water or submersion below shallow depths can compromise the water resistance of your Apple Watch Series 9
Avoidable Actions
- Avoid exposing your Apple Watch to soap, detergent, acids, or high-velocity water, which could affect the water seals and acoustic membranes.
- After swimming, rinse your Apple Watch under lightly running, warm, fresh water, and dry it thoroughly.
- If your Apple Watch gets wet and the speaker sounds muffled, avoid inserting anything into the openings and allow it to charge overnight to speed up evaporation.
Water Lock Feature
Engage the Water Lock feature during swimming workouts to prevent accidental screen taps. In the event of water ingress, clear it by unlocking the screen and turning the Digital Crown to play a series of tones to expel the water
How to turn on Water Lock
- To open Control Center, press the side button (for watchOS 9 or earlier, touch and hold the bottom of the screen, then swipe up). You can open Control Center from any screen.
- Tap the Water Lock button
. The Water Lock icon 
appears at the top of the watch face.
Bottom line
A WR50 rating shows that the Apple Watch is good for light swimming and bathing, but it's not made for water sports or other heavy water activities. This makes it a good choice for fitness fans who like lap swimming. However, if you love spending a lot of time in the pool or the sea, this might not be the water-resistant watch you're looking for.
