Mechanical Watch Service Geneva: Complete Restoration of a Tissot Automatic
This Tissot automatic was entrusted to our watchmaking workshop in Geneva for a complete movement overhaul following reduced performance and irregular operation.
The owner reported:
- Reduced power reserve
- Unstable accuracy
- No maintenance performed for several years
- Uncertain water resistance
Before any work began, we carried out a full diagnostic, including movement inspection, internal visual examination, and water-resistance testing.
Initial Diagnosis
During the initial inspection, several technical issues were identified:
Insufficient Mechanical Performance
- Irregular amplitude
- Worn mainspring
- Aged and partially dried lubricants
Internal Wear
- Early signs of wear on certain gears
- Degraded oils reducing energy efficiency
- Loss of optimized torque transmission
Water-Resistance to Be Secured
- Old gaskets
- Moisture protection no longer guaranteed
These findings made a mechanical watch service in Geneva essential to prevent premature wear of the movement.
