User level: Level 1 (4 points)I’m unable to pair my watch (model no A2351) running on version 10.6.2 to my new iPhone 18 pro. Are they incompatible?

They may be incompatible because of the watchOS version, rather than the iPhone model itself.
Model A2351 is an Apple Watch SE (1st generation). Apple lists this model as supporting watchOS 10 only up to version 10.6.1, so the reported version 10.6.2 is worth double-checking.
Try updating your iPhone 18 Pro to the latest available iOS version, then restart both devices and try pairing again.
