Watch Winder

This DIY watch winder, powered by the widely available Bambu Lab TT motor, offers an affordable solution for watch enthusiasts. The motor, which I measured to spin at approximately 45 RPM, is slowed down to 0.5 RPM using a 90:1 gear ratio. This results in around 750 rotations per day, an ideal range to keep most automatic watches wound. However, some watch movements can be prone to overwinding, so it’s important to research your specific watch. The winding assembly is mounted on a 65-degree stand to ensure proper rotor movement, even in budget-friendly automatic movements like the NH35 in my watch. Additionally, I included a cutout for a 20mm diameter toggle switch, making it easy to switch the device on and off once wired up (the switches I ordered are still on the way). I also extended the motor wire by splicing in a few extra feet, allowing the unit to reach an outlet from my desired location.
