Sorry, I still don't understand your question.

Apple Care is not transferable if you have it on a device.

If you bought a new Watch, you can return it within 14 days and buy something else.

If you have a different question, please be more specific and provide more details.

Not sure what you're asking?

You can buy Apple Care when you have the new Watch.

Apple Care is tied to the device and is not transferable to another device.

If your Watch trade-in is successful, you get a voucher anyway and can use it in any Apple Store.
