Your First Homemade Watch Winder

Once you’ve finally assembled the watch winder unit, you’ll truly be excited flicking the power switch for the first time. Well, I was!

As mentioned earlier, I’ve eliminated any possibilities of friction and ensure smooth rotation by using a total of four ball-bearings in this unit. The latter also enables a small DC motor to rotate smoothly. The design is “crude” but it works. I’ve only covered the watch cup with micro-suede because I was too anxious to complete the whole unit.

This unit has 4 modes of operation: -
  • 800TPD - CW
  • 800TPD - CCW
  • 900TPD - CW
  • 900TPD - CCW
At Rest, the circuit draws only about 2mA and depending on the weight of the load, when Rotating it draws as high as 60mA.

The unit functioned as designed and planned for. I will post my updates on a later date.




This was my preliminary sketch of the mechanical construction of the unit. Most of the parts are readily available from scraps, except for the ball-bearings.












I started with making a watch holder, seen here at the top of the picture (left).














This is how it looked like fully assembled from the front.

Only few components were required for this circuit and two such circuits could easily fit into a tiny 5 by 7cm veroboard. This means you could build a Two Watch Winder for yourself.




















This video clip shows how it works...
