I still have an original Pebble someplace, and to this day it was the only smartwatch that actually got calendaring “right”–its timeline view was an excellent bit of UX that Apple completely ignored (they even killed doing “time travel” with the crown recently, so it’s pretty much impossible to have a decent overview of your day at a glance).
It’s good to know bits of it live on, although realistically it is extremely unlikely to ever recover and come back as a commercial product, regardless of the brilliant engineering involved.
