Turn off search for apple watch

Hi and welcome to the Apple (user-to-user) Community!

Re: "Turn off search for apple watch: I do not have an Apple watch and I think it is interfering

with my hearing aids connecting, so I want to turn it off".

If you have once had a Watch listed in your settings:

1. Try going to Settings > Bluetooth.
2. Tap next to the watch you want to unpair, then tap Forget This Device.
3. Tap Forget Device to confirm.

If you don’t see the devices list, make sure Bluetooth is turned on

Above is from "Unpair a Bluetooth accessory" in Connect iPhone to Bluetooth accessories - Apple Support

All the best :-)
