Description

This new reference 11 C Automatic wristwatch based on in-house Caliber UJS P8 results from
specific development research using the following special elements:

1. a system of 3 screws fixing , which is easily accessible to all watchmakers
2. the pivot and spring barrel bridge are intimately connected with each other reducing frictions.
3. the gold rotor mounted on jewel bearing results in a simplified automatic system with little
vulnerability for failure.
4. the unidirectional winding rotor and its ratchet wheel, which boasts an optimized tooth shape,
is perfectly user-friendly and effective.
5. five jewels in the bridge prevent the rotor being damaged even if it experiences great shock.
6. rotor weight: 3.86g, 22K

The prototypes of the caliber P8 are certified by the laboratories Chronofiable SA and the
C.O.S.C. with 40% better results on 300 other brand watches.
