Introduction
MPS Micro Precision Systems AG is a key partner for major watch manufacturers, specializing in the production of large diameter watch bearings since 2005. These bearings are crucial for various watch functions, including automatic winding and movement rotation.

Specifications and Features

• Automatic winding is achieved through a peripheral oscillating weight, allowing a full view of movement components via a transparent back.
• The bearings serve as a base for the rotation of the movement around its axis and for driving indicator elements.
• Integration of shock absorbers enhances shock resistance and reduces noise emissions.

Manufacturing Challenges and Innovations
The production process involves mastering the fabrication of rings with diameters up to 40mm and minimal cross-sections. Specific control systems have been developed to measure these components, which are prone to deformation under stress. MPS has pushed the boundaries of feasibility, achieving complex shapes and high-quality finishes.

Applications and Solutions

• Large diameter bearings are used for peripheral oscillating weight winding and as a base for movement rotation.
• High-speed ball movement can cause micro-vibrations and noise, which MPS mitigates with innovative shock-absorbing solutions.

Conclusion
MPS continues to innovate in the field of large diameter watch bearings, providing essential components that enhance the functionality and performance of luxury watches.
