How to Reset or Force Restart Your Apple Watch

There are a couple of things you can try in case your
Apple Watch

stops responding for some reasons. This guide explains what you can do if your Apple watch is misbehaving.
The first and most direct resolution is to reset your Apple Watch, which is essentially a way of turning it off and on again. This is helpful in case
an app has crashed and a
standard force quit

doesn’t troubleshoot the problem, or if the live data exchange between your iPhone and Apple Watch appears unpredictable.
Keep in mind that you can’t restart an Apple Watch while it is charging, therefore, unplug it first from the charger before trying the following steps.

How to Restart an Apple Watch

Press and hold the side button until the Power Off slider appears on the screen.
Using your finger, drag the Power Off slider.
After your Apple Watch has turned off, press and hold the side button again until the Apple logo appears.

In case that didn’t troubleshoot your problem, you can give your Apple Watch a force restart. Note that this should only be used as a last option. And whatever you
do, don’t initiate a force restart if your Apple Watch is in the middle of an OS update.

.

Long press the Power Off slider and then release.
Now, tap Erase all content and settings.
