For the past 3 months I've been toying with an idea to make a very simple watch winder so that members (technical personnel) can learn the very basics.
This is what I've come up with! Introducing TOM...

This is another DIY Homemade Watch Winder you can easily make from most household items.
The Orbital Triple Arm
Consist of…
- 1pc Y-type water hose coupling
- 3pcs round rubber washers
- 3pcs watch cuffs
- 3pcs precision ball-bearings
- 3pcs wooden dowel
The Base
Consist of…
- 1pc stainless steel container
- 1pc AC motor (with securing screws)
- 1pc toggle switch
- 1pc power socket
- 1pc LED
The Assembly
The Orbital Triple Arm has a small hole beneath where it is mounted on the motor shaft.
General Background
Automatic watches wind in a clockwise (CW), counter-clockwise (CCW) or either way (bi-directional). In addition, they require specific minimum number or turns to stay wound and keep time. This number of turns is called Turns per Day (TPD)
TOM is a simple watch winder that turns either in a CW or CCW direction. Winding direction can be changed when you switch OFF and then ON again. So user must know what their respective watch requirements and to select its appropriate winding direction. By itself, this machine will deliver 7200TPD when left unattended in a day. An external timer is required, or you may just switch it ON for, say 2 to 3 hours and then leave it. Your choice!
Working Principle
1) The AC Synchronous Motor is connected to the Y-type coupling and rotates.
2) Each outlet of the coupling is equipped with a precision ball-bearing that will turn each of the wooden dowel effortlessly.
3) To assist the dowel turning, a rubber washer is attached on each one.
4) To further ensure the arms rotate, I’ve added a rough circular anti-skid ring made from paper and coated with EVA glue.
5) All this will result in the three arms orbiting and rotating on its axis simultaneously.
TPD Calculations
1) The AC Synchronous Motor turns at a rate of about 5rpm and if not reduced will produce 7200 Turns Per Day (TPD) which is much too high.
2) To reduce its TPD, you have two choices…
a) use an external timer, or
b) use an electronic timer that switches ON the motor at intervals
3) I have selected the latter in which I used a simple electronic circuit. Video shows TOM without the electronic circuitry.
4) This circuit switches ON for a minute then pauses for 10 minutes. In a day, it’ll achieve just about 650TPD.
5) Here’s the formula…
(1440/11) x 5 = 654TPD (approx)
TOM stands for Triple Orbiting Machine
Warning
This project uses 230VAC and should not be attempted by non-technical personnel. I will not be blamed for any deaths or injury resulting from this project.
