How do you find the Apple Watch ?

Hi

There is presently no way to physically locate Apple Watch (in a similar way to how Find My iPhone can be used to locate a misplaced iPhone).

Unlike some other Apple devices, the watch does not have built-in GPS capabilities.

If your watch has been lost and Activation Lock was enabled, consider using Mark as Missing in the Watch app on your iPhone:

If your Apple Watch ls lost somewhere close to your iPhone and still within Bluetooth range of your IPhone, or if you have WiFi calling enabled and your Apple Watch is within range of a WiFi network your iPhone has connected to before, and you are close enough to your Apple Watch to hear it, you could try telephoning your iPhone, which would cause your Apple Watch to ring.

This is not necessarily correct.

Apple Watch will not ring if it is locked (when passcode and Wrist Detection are enabled, for example, this happens automatically upon removing your watch from your wrist).
