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

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.

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.
