Mechanical Watch Service Geneva: Complete Restoration of a Breitling Chronomat
This Breitling Chronomat automatic was entrusted to our Geneva watchmaking workshop for a complete mechanical overhaul following significant performance issues.
The owner reported:
- Irregular timekeeping
- Malfunctioning chronograph functions
- Noticeable loss of accuracy
- No servicing carried out for several years
Before starting any work, we performed a comprehensive technical diagnosis, including a full movement inspection, critical component analysis, and a professional Witschi timing test to evaluate the actual condition of the caliber.
Initial Diagnosis
During the initial inspection, several major issues were identified:
Advanced Mechanical Wear
- Damaged minute wheel
- Faulty calendar driving finger
- Worn mainspring
- Excessive play in multiple components
Chronograph Module Malfunction
- Worn reverser mechanism
- Corrector lever requiring replacement
- Minute counter jewel needing repositioning
- Chronograph hammer requiring adjustment
Disrupted Energy Regulation
- Unstable amplitude
- Loss of torque transmission
- Degraded, aged lubricants
Water Resistance Issues
- Aged gaskets
- Insufficient protection against moisture
These findings made a full mechanical watch service in Geneva essential to restore reliability, precision, and long-term durability.
