Breitling Chronograph Repair in Geneva – Mechanical Watch Overhaul by Our Geneva Watchmaking Workshop
This elegant Breitling Premier chronograph was entrusted to our Geneva watchmaking workshop for a full mechanical overhaul following major chronograph malfunctions and irregular timekeeping.
The owner reported:
- Irregular timekeeping
- Chronograph reset malfunction
- Reduced amplitude
- Minute counter jumping
- No complete service for several years
Before any intervention, our watchmakers carried out a full Witschi timing analysis, amplitude measurement, and complete mechanical inspection to determine the condition of the movement and chronograph module.
Initial Diagnosis
During inspection, several major technical issues were identified.
Barrel and Power Transmission Issues
- Broken barrel spring hook
- Excess play in the barrel arbor
- Reduced tension affecting the ratchet wheel
- Loss of torque transmission
Chronograph Module Malfunctions
- Incorrect chronograph bridge screws (conical instead of flat)
- Excessive play in escapement wheel
- Minute counter jewel misaligned
- Reset hammer adjustment required
- Chronograph control spring screw not properly fitted
- Minute counter jumping during activation
Escapement & Regulation Problems
- Hairspring flatness defect
- Beat error present
- Excessive shake in gear train
- Pallets required repositioning
Wear & Aging
- Old degraded lubricants
- Internal friction due to dried oils
- Signs of long-term mechanical fatigue
The timing machine results at reception confirmed unstable amplitude and inconsistent performance across positions.
These findings made a complete mechanical watch overhaul in Geneva absolutely necessary.
