Because there’s a new apple id on the phone, it asks for a new password. It might be old DRM audio or apps on iCloud that are prompting the phone or watch to request those users’ passwords, as they haven’t downloaded any music yet. Settings General is where you’ll find this option.
The original owner of the device, and therefore the iPhone on which the Apple Watch was linked, has direct access to the iPhone and can simply unlink the Watch from it. An iOS gadget will lose its activation lock after this operation is completed. They’ll need access to an iPhone’s Apple Watch app.
Log in to iCloud.com using your Apple ID and password. You may use this page to locate My iPhone if it is lost or stolen. All Devices will list all of the devices linked to your account, and you can pick the one you wish to delete. Then hit Remove from Account
Select the General option from the Apple Watch’s Settings app. Select the Reset option and then press Erase All Content and Settings. You’ll be prompted to enter your passcode if you have one. Tap Erase All again, and your watch will begin deleting data.
