Here are some pictures of the watch assembly (I am only missing front glass cover). Back cover is made out of 1 mm thick aluminium. Transparent cover would also work so that the PCB can be seen (will tray that out). Case is printed with PLA 0.1 mm layer height. Watch is 15.5 mm in height and 50 mm in diameter and strap is 22 mm wide. As soon as I get some free time I will make video to show watch working and how it fits on the hand.
