Having finally gotten a hold of a Pebble Android smartwatch, the folks at iFixit took a gloves-off approach to seeing what made it tick.
Basically, they disassembled it, finding that the device had surprisingly few independent components.
Sadly, the watch doesn't have any screws, none that are visible or reachable in any way.
Thus, tearing it apart demands that the outer shell be pried loose, something that the adhesive holding it together won't allow to happen without a fight.
In the end, the Pebble was found to use a single ribbon cable, four buttons, three LEDs, a Bluetooth antenna, an e-ink screen, a battery (life of 10 years supposedly) and the shell and strap of course.
Sadly, once the watch has been taken apart, it can't be put back together again, definitely not back to its waterproof self.
