I bought an Apple Watch and it has a previous owners Apple ID and it won’t unlock

Have you bought 2nd hand Apple Watch?

You must contact the seller (hopefully it is the previous owner), otherwise you have been scammed.

Each Apple device is linked/associated with an Apple ID of the person who did the setup.

Activation Lock prevents anyone who is not the owner from using this Apple Watch.

To unlock the Apple Watch, you need the Apple ID and password of the previous owner, that were used during set up.

So you have to contact the seller / previous owner.

The seller / previous owner has to read -> this Apple article: What to do before you sell, give away, or trade in your Apple Watch, or buy one from someone else

Then the seler / previous owner has to remove the Apple Watch from his account, see this Apple article:

Check your Apple ID device list to see where you're signed in
