Follow these instruictions:

How to erase your Apple Watch if you don't have your iPhone (or it is bused)

On your Apple Watch, tap Settings > General > Reset > Erase All Content and Settings. 

Type your password if prompted.

For GPS + Cellular models, choose to keep or remove your mobile data plan.

• • If you want to pair your Apple Watch and iPhone again, keep your plan. 
  • If you don't want to pair your Apple Watch and iPhone again, remove your plan. If you aren't going to pair with a different watch or iPhone, you may need to contact your network provider to cancel your mobile data subscription. 

Tap Erase All to confirm. This resets your Apple Watch to the factory settings.

Now you can set up your Apple Watch again. You'll need the Apple ID and password associated with the watch to turn off Activation Lock.
