Couldn't the same flow be achieved on a Pebble watch by utilizing something like the "double tap"-gesture Apple Watches Series 9 and upwards have?
This seems like a gadget just for the sake of having another gadget...
Interesting idea, but those gestures only work on AW when not in low-power mode, meaning they take a non-trivial amount of battery. It would probably dampen Pebble's battery life significantly, and might not even be possible with the chip that it has.
The idea (fta) is to have activation require only the one free hand.
The double-tap gesture is something I was very excited about and have completely forgotten about since getting my watch. The caveats around what it takes to activate it (screen activated and facing vertically) are just so great, you wonder if anyone at Apple actually tried this and found it to be a better alternative to interacting with the screen. Their demo video actually does a perfect job of capturing just how ridiculously theatrical you have to be to get it to work: https://support.apple.com/guide/watch/use-double-tap-for-com...
