Hello.
This article goes over the service and repair options for Apple Watch. I quoted the Express Replacement Service info but more options are available.
watch Repair - Official Apple Support
"If your Apple Watch is covered by an AppleCare+ plan, you can also request Express Replacement Service. We will send you a replacement before you send us your Apple Watch. Your replacement Apple Watch will have factory settings.

I hope this helps.
