With iOS 17.1 and watchOS 10.1 being released today, for those that own an Apple Watch Series 9, you can now use the new Double Tap feature.
To check out the options, go to the Apple Watch app and select Gestures/Double Tap.
Release Notes: Double tap gesture can be used to perform the primary action in notifications and most apps so you can answer a call, play and pause music, stop a timer, and more (Available on Apple Watch Series 9 and Apple Watch Ultra 2)
Good catch, never realized that until I read your comment.
