I also had a pebble 2 hr, even had two because I bought another one off eBay (unopened box). 3d printed some buttons and used is for many years until the battery basically died, and the software started to show it's age. Notifications became unreliable and such things, making it kinda pointless.
Still want nothing more than for it to work properly again. It's easy enough to swap the battery, now with the ability to fix the software, there might be a point to it.
