History (4): chronosport inhouse movement

Published on September 15, 2019 at 9:30 AM

Invicta was founded in 1837 by Raphael Picard in La Chaux-de-Fonds. His sons led the company at the end of the nineteenth century under the name Les Fils de R. Picard (the sons of R. Picard). It was a production that made its own movements in Delémont and Le Locle, and at the beginning of the twentieth century one of the company's most famous caliber was a minute repeater.

 

It seems that other companies such as Omega and Lemania made use of this caliber. Eventually the name of the caliber was then used for the company itself.

 

The Invicta Chronomontre was patented by Henri Jacot-Guyot, watchmaker from Neuchâtel, on 24 March 1932. It is a rectangular watch with a crown and a single pusher that is in fact a lever.

Although the watch was called "Chronomontre" when it was presented at the Basel fair in 1933, the name on the dial was "Chrono-Sport". Here the 2 known versions:

There are 2 counters on the dial: on 6 it is a 30 min counter and on 12 the counter has 2 functions. In a small window there is a disc that rotates when the chronograph starts. It is a one-minute counter. But there is also a hand that works with the disc, but not with the same speed: it makes a full turn (counterclockwise) in 10 seconds and can therefore indicate 1/5 of a second. The caliber is a rectangular 8.5 / 12 lignes with the chronograph mechanism under the dial.

 

This watch is hard to find. According to Gisbert L. Brunner, only 50 samples were made. It could be a bit more because some samples were made with spare parts in the 1980s.
