This a watch that I have created in order to reuse an old watch mechanism I had. The glass used for this design has a diameter of 30.5 mm and a thickness of 1.36 mm. Instructions for assemble it: For the joints between the differents parts of the chain you will need 1.75mm width * 19.3mm long pieces of cable (I used 3D filament for this). And then glue them to exterior parts. I will try to create more chains and cases for the watch so they can be interchanged and you have the Fusion file if you want to adjust it yourself.
