Bluetooth pairing issue with AirPods on Apple Watch 10.6.1

Ive been gifted some Apple ear buds 2nd edition but they won’t pair with Bluetooth on my Apple Watch 10.6.1. No problem pairing to my iPhone 12 or my iPad when Bluetooth is on. I have turned off Bluetooth on my all other devices but they still won’t pair. What am I doing wrong?
