Instead of glass i used 2mm thick plexiglass.

My arrangment of arduino is Pro mini soldered directly to LED with resistor, 4 buttons (one works as "safety"), TM1637 7 segment clock display and 2 wires for connecting battery.

My watch are accurate for 2 seconds a day, have timer function and battery for cca 14hrs.

Plate for holding display in place is not part of 3D models.

Bottom part is glued to mid part and glass is glued to cover. 

Everything is held together by 4x 25mm M3 screws, armband width is 37mm.
