Bought an iPhone 12, I cannot connect my iWatch. The iWatch i con does not show up in the iWatch

Thanks for the quick response fieryjack, I was able to remove the watch as you advised. The iWatch is still not showing up to remove, I wonder if it takes icoud time to update its servers. Also I am in a different city with server from the initial iWatch setup. I will keep trying, thanks for being awesome, much appreciated.

Thank you fieryjack, I can not remove from old iPhone, not found. I have the first generation iWatch, I see the link sent was for 5, 6 and 7 iWatch. The watch on my old phone is not found on the old phone. The transfer of data from old to new phone may have disconnected on old phone.
