When you were an apprentice at Patek Philippe, what were you working on?

One of the best things during the Patek Philippe apprenticeship is that you have the chance to stop at every main workshop, and so you are able to see and learn the entire watchmaking process. The aim of that method is to help the apprentice to become as independent and productive they can be. Thanks to that the trainee becomes aware of all the watchmaking process and after three years is able to assemble by himself an entire watch. I remember that my best experience was in the quality control when I discovered for the first time the tourbillon 10 days power reserve – at that moment I knew I would make my own tourbillon.
