Hi
You might wish to use the following settings. With this configuration, an incoming notification will be displayed in summary form (email or message) when you raise your wrist upon receiving the notification alert (without needing to tap the screen) and in full if you keep your wrist raised for a few seconds:
- On your iPhone, in the Watch app, go to: My Watch (tab) > General > Wrist Detection - turn this on.
- On your iPhone, in the Watch app, go to: My Watch > Passcode > Turn Passcode on (choose either a Simple Passcode or a more complex one).
- Also on the Passcode settings screen, enable Unlock with iPhone.
After putting it on your wrist, your watch will then unlock after whatever you do first: either unlocking your watch manually (by entering the passcode) or unlocking your iPhone.
It will then remain unlocked (including when the screen is asleep) until you remove it from your wrist. When you remove your watch, it will lock automatically.
