I haven't been using my watch for a long time mainly because of the delicate nature of having a exposed PCB as the watch face. To make the watch more practical to wear I designed and 3D printed a case last night :-)

The PCB is still used as the bottom of the watch and the top case is held in place by looping a "NATO band" trough the case and PCB. The "watch Crystal" is made out of a piece of plexiglass and press fitted in to the case.

The case was designed in Design Spark Mechanical
