Unable to reset my Apple Watch

Hi savvas32,

Thanks for posting in Apple Support Communities.

We understand you're having trouble with your Apple Watch and you have reset it, but it sounds like you're unable to pair it back again.

Erase Apple Watch without the paired iPhone

If you can't unpair Apple Watch because you don't have its paired iPhone, you can erase the watch.

When you erase Apple Watch instead of unpairing it, the watch is still protected by Activation Lock. Before you can pair Apple Watch again, enter the Apple ID and password that was used to set it up.

1. Open the Settings app on your watch, then tap General > Reset.

2. Tap Erase All Content and Settings, then tap again to confirm.

3. Wait for the watch to unpair.

4. After Apple Watch unpairs completely, you can pair again. You'll need the Apple ID and password that were used to set up the watch.

Reset Apple Watch without using a passcode

If you can't unpair or erase your Apple Watch because you’ve forgotten its passcode, you can reset the watch.

When you reset Apple Watch instead of unpairing it, the watch is still protected by Activation Lock. Before you can pair Apple Watch again, you'll have to enter the Apple ID and password that was used to set it up.

1. Put Apple Watch on its charger.

2. Press and hold the side button until you see the screen with the power button  in the upper-right corner, then let go of the side button. If your Apple Watch has an earlier version of watchOS, you see the Power Off slider instead of the power button.

3. Press and hold the Digital Crown until you see the red Reset button.

4. Tap Reset, then tap Reset again to confirm.

5. After Apple Watch unpairs completely, you can pair again. Remember that you'll need the Apple ID and password that were used to set up the watch.
