Automatic Watch Winder

Automatic Watches are great because they do not need batteries; but to wind them you have to wear them! This watch winder is capable of winding three automatic watches so they are set to the correct date and time when you are ready to wear them.

The geometry of the watch winder was driven by the spare parts that I had in inventory including a NEMA 17 motor, an Easy Driver, some bearings, 8mm rod, velcro, 3mm machine screws, Arduino Uno, Relay, Fan (cool the driver) and 2020 from an old 3d
