My wife's Pebble 2 Smartwatch broke yesterday. One button separated and
now is missing (these "buttons" are just a block of rubber). We tried
to glued it but it worked for only a short time.
The problem is that without one button the watch cannot be used.
Fortunately, we still have the Pebble Time Steel. They are older but
they are more solid. I hope they will be able to survive several years
at least.
