Geneva Trip and Bench Test!


Week 36 

This week we had another bench tester! Alexander from Israel! 

Here is Alexander working on assembly of a ETA 7001 movement.

    Last weekend, we traveled to Geneva Watch Days to visit several brands to get to know the brand and see their new releases during the exhibit at Beau Rivage.

An original Czapek pocket watch which was used as the basis for the design language of the revived brand. 

The Quai des Bergues, which was Czapek's first model after their revival in 2012. Designed with the DNA of the original pocket watch.

Place Vendome Tourbillon, with GMT across from the tourbillon to mirror the design language of the Quai des Bergues.

Lederer's Central Impulse Chronometer in rose gold. It has 2 gear trains that are regulated by 1 central balance wheel.

Moser's sister brand Hautlence's new creation which tells time by using a retrograde minute and a polished blue sphere that spins to display the next hour.




Workshop A

Amer, Dunham, Daniel, David, Harold, Miguel 

     This week Miguel and David took their practice exams for pivot gauges. It was quite difficult, but their skills are improving!

     Daniel made several practice pivot gauges in preparation for the exam.

    Amer and Dunny are learning how to do poising and timing of the balance and hairspring.

    This week Harold learned about and practiced on the disassembling, cleaning, and lubricating the arbour, barrel, and mainspring, installing the mainspring manually and with a winder and closing the barrel. Adjusting the end shake and side shake were also learned and practiced. Factors that affect isochronism were learned. How to properly use the cutting and smoothing broches was learned and practiced.


Workshop B 

Dean, Faris, Ivan, Louis, Tetsu, Varun


    This week, Dean had an amazing restoration project! He had to repair a Zenith pocket watch which had an off center bushing for the balance wheel.
