By Leone, 19 May, 2016 Forum watchOS and Apple Watch Apps Hi Guys. I’d like to know how to set the alarms on my Apple Watch to vibrate, i don’t know how to do it, Options Log in or register to post comments Comments Hello! Hello! They should definitely vibrate by default. Make shure you have the haptic features in watch settings / sounds&haptics enabled. To have only the vibration, turn on the mute function from the settings glance or silent mode from your iPhone's watch app.
