TL;DR
A maker has designed a custom watch case through 3D printing, incorporating a standard Miyota movement and a bayonet connector for easy assembly. This project highlights innovative approaches to DIY watchmaking. Details on the full build are emerging.
A maker has created a custom watch case using 3D printing techniques, incorporating a Miyota 8N24 movement and a bayonet connector for assembly. This development demonstrates innovative methods in DIY watchmaking, blending traditional components with custom fabrication.
The project involves 3D printing a watch case designed to hold an off-the-shelf Miyota 8N24 movement. Instead of traditional screw-in or press-fit backs, the design uses a bayonet connector, which provides a robust and easy-to-manufacture attachment method. The case was printed with a focus on modifiability, allowing for adjustments such as crown placement.
While the movement and crystal are standard components, the case itself is a custom design that emphasizes simplicity and reliability. The project was shared on Hackaday, illustrating both the technical approach and the lessons learned from combining 3D printing with conventional watch parts. The maker’s approach aims to make DIY watchmaking more accessible and customizable.
Innovative Approach to DIY Watch Construction
This project is significant because it demonstrates how 3D printing can be integrated into traditional watchmaking, making it more accessible for hobbyists. The use of a bayonet connector simplifies assembly and disassembly, potentially leading to more modular and customizable watches. It also shows how off-the-shelf components can be combined with custom-fabricated parts to create functional, personalized timepieces.

Background on DIY Watchmaking and 3D Printing
DIY watch projects have gained popularity among makers for their blend of craftsmanship and technology. Previous efforts often relied on custom machining or complex assembly methods. The recent trend involves using 3D printing to create watch cases, which reduces cost and complexity. However, integrating standard movements and reliable attachment mechanisms remains a challenge. This project builds on these developments by employing a bayonet connector, a common method in traditional watch design, adapted for 3D printed parts.
“Using a bayonet connector in a 3D printed watch case offers a simple yet effective way to attach the back cover securely while allowing for easy modifications.”

Key Questions
Can I replicate this watch design at home?
Yes, if you have access to a 3D printer and basic watchmaking tools, you can attempt to replicate the design using the shared plans and standard components like the Miyota movement.
What materials are suitable for the 3D printed case?
Common options include ABS, PETG, or other durable plastics suitable for wearables, but the choice depends on desired durability and finish.
How reliable is the bayonet connector for long-term use?
While the bayonet connector provides a simple attachment method, its long-term reliability depends on material choice and manufacturing precision. Further testing is needed to confirm durability.
Will this approach work with other watch movements?
Potentially, yes. The design can be adapted to accommodate different standard movements, but adjustments to the case and mounting points may be required.
Is this project suitable for beginners?
It requires some familiarity with 3D printing and basic watch assembly, so beginners should proceed with caution and review detailed instructions before attempting.
