Hi
To stop your Apple Watch from announcing the time when you raise your wrist:
On your iPhone, in the Watch app, go to: My Watch (tab) > General > Accessibility > VoiceOver:
- Turn off VoiceOver (the main setting at the top).
- Turn off Speak on Wrist Raise (further down).
To help prevent accidentally enabling VoiceOver again:
On your iPhone, in the Watch app, go to: My Watch > General > Accessibility > Accessibility Shortcut:
- If a check mark is shown against VoiceOver, deselect it / remove the check mark.
