Description
3-Watch Winder
Overview
This 3-Watch Watch Winder is designed to keep up to three automatic watches wound simultaneously. It uses a planetary gear arrangement to distribute motion from a single motor, creating an efficient and visually engaging watch winder.
The design features a clean, minimalist appearance while prioritizing ease of printing, assembly, and maintenance. Most components can be printed without supports, and all non-printed hardware is readily available online.
Features
- - Winds up to 3 automatic watches simultaneously
- - Designed for automatic mechanical watches
- - Compatible with most watches using bracelets or straps
- - Planetary gear-driven mechanism powered by a single motor
- - Uses one central sun gear and three planet gears
- - Exposed mechanical gear movement for a visually interesting display
- - Clean, minimalist design
- - Functional 3D printed watch accessory
- - Easy to print with minimal support material
- - Most parts are support-free
- - Hardware and motor components are easily sourced online or from local hardware stores
- - Great project for watch collectors, makers, and 3D printing enthusiasts

Spacers
- 5/16" Inner Diameter
- 5/8" Outer Diameter
- 3/4" Length Steel Spacer
I purchased these from Home Depot's specialty fastener section, though I was unable to locate the exact item online.
Washers
- 3/8" Inner Diameter
- 7/8" Outer Diameter
Assembly
Assembly is completed using screws and standard hardware listed above.
The motor drives the central sun gear, which transfers motion through the three planetary gears to rotate each watch holder simultaneously.
Print Recommendations
- PLA recommended
- Most parts print without supports
- Supports are only required for the Stand to achieve the best surface quality
- Print gears at a finer layer height for smoother operation
- Ensure accurate dimensional calibration for optimal gear meshing
Design Inspiration
The mechanism was inspired by planetary gear systems commonly found in automotive transmissions. I was interested in adapting this efficient mechanical arrangement into a fully printable watch winder that combines functionality with visible mechanical movement.
This project is part of my ongoing exploration of printable watch accessories, kinetic objects, and mechanical design.
If you build one, I would love to see your make and hear any suggestions for future improvements.
