Watch Winder

Watch Winders are devices that keep self-winding automatic watches running when not worn. They are a popular, necessary tool for watch collectors. Automatic watches use mechanical movements, powered by a rotor or weight that uses gravity and the constant motion of the wrist. The watch winders slowly spin the watch some minutes per day, keeping it charged. But these devices are rather expensive!

I offer you one on a low budget: the total cost is less than 20$.

This Watch Winder rotates for 10 minutes every 50 minutes (Cycle mode: 10minutes On/50minutes Off).

You need only: 

- n.1 DC 12V Power Adapter (±5.00$)* 

- n.1 Timer delay rele 12V with 'Cycle Mode' (±4,50$)* 

- n.1 DC 12v Synchronous motor 5rpm (±6,00$)* 

- n.3 Cable ties 

*(You can bought them on amazon or ebay)

1. You have to block the engine with two cable ties on the 'Watch Winder Box.stl' (as in the picture). 

2. Then insert the 'Watch support.stl' on the engine and block it with one cable ties (as in the picture). 

2bis. You can optionally print the 'Timer delay Back cover.stl' to protect the timer delay circuit. 

3. After the wire connections (as in the picture), on the Timer Delay you have to simply switch on the Cycle Mode and set the off time on 50 minutes and the on time on 10 minutes. 

4. Insert the Timer delay in the back and close the box with the 'Box back cover.stl'. It's an interlocking pieces, you don't have to use glue.
