Be careful: the top LED fell out when disassembling the watch. The two LEDs feet are mounted between two contact springs. Those are only visible with a loupe. When I first assembled this watch, the 12 o'clock LED was not always making good contact.

The rest of the assembly is fairly straight forward, although the spring load of the battery (CR2016) holder is quite stiff and requires a confident push down on the battery when re-inserting.
