Watch cups were fixed with bearing on the back panel and rotated and guarded by front panel. To ensure prefect contact, watch cups shall be heated with hot water or hair dryer and then pull fit into panel and turned for 10+ rounds until smooth to run. Finally, some grease may add on it for easy of turning. For the watches, it was fixed into cups with oval shaped spongy material (cut from heat pipe insulation materials).

Noise may be generated during the operation, please review the specifications of the driving motor for its operation voltage. If it is possible, please use a low noise geared motor as in crystal display stand. IC, LM317 may be used to step down the voltage in order to slow down the driving motor such that noise can be reduced. In my case, 5V USB adopter of mobile phone was used as power with a LM317 to convert voltage to 3.9V with 475 ohm and 1k ohm resistors. It is programmed to run 3 times every day via 7 x 24 hrs. digital timer plug.

Optional functions such as AIY with raspberry pi and powered by USB for mobile docking or charging stand.

If you do not want to print or make one, you may buy a watch winder in below link from me in a more reasonable price.
