What is water lock on apple watch?

The Apple Watch doesn't have a feature explicitly called "water lock." Instead, it uses a combination of features to protect it from water damage and to help prevent accidental inputs when wet. These features work together to provide water resistance:

• Water Resistance Rating: Apple Watches (except for the original Apple Watch) have an IPX8 water resistance rating, meaning they can withstand submersion in water under specific conditions (depth and time vary by model; check your specific watch's specifications). This is not waterproof; it's water resistant.

• Water Lock (Implied Functionality): When you're done swimming or showering, the Apple Watch interface will often display a small water droplet icon near the time. This is not a lock in the sense of blocking access, but is a visual cue. Activating the crown (the digital crown) will then initiate a quick spin cycle to remove any water that may have entered the speaker. This is what users often refer to as "Water Lock" though it's not an official term Apple uses. This is crucial for sound after exposure to water.

• Preventative Measures during Water Exposure: The important thing is to prevent water from entering the microphones, speakers, and other openings. When engaging in water activities, ensure the crown is firmly screwed and the watch is generally clean and free of debris that might seal around the openings. Avoid extremely hot water or high-pressure water (like powerful showers or jets).

In short: There's no "Water Lock" setting you explicitly toggle. The water resistance is a built-in feature, and the post-water-exposure water expulsion procedure via the crown is the closest thing to what people might call a "Water Lock." It's more accurate to refer to it as the "water removal" process. Always consult your Apple Watch's user manual for the specific water resistance capabilities of your model.
