Aim of the course:

To give the participants both a theoretical understanding and practical experience at the bench of these different chronographs, with particular emphasis on fault finding, repair and fine adjustment of the chronograph mechanism.



This 3-week program is based on 4 different chronographs, chosen specifically to represent all of the types of mechanism in current production.

  • Theory
  • Practice
  • Examining vintage column wheel chronographs such as Valjoux 23


Participants (min. 4 / max. 6)

Participants must have followed a watchmaking school and have a complementary experience in watch repairing. Watchmakers with no such basic training must have a minimum of 3 years full-time experience in watchmaking.

The course is intended for watchmakers whose daily work brings them into contact with these chronograph watches and would be particularly interesting for anyone wishing to progress towards working with higher complications.



8:30 to 12:00 and 13:30 to 17:00
