Chronomètre FB1 by Ferdinand Berthoud : a Tourbillon Marine Chronometer on the Wrist
Before presenting you the FB1 Marine Chronometer tourbillon watch by Ferdinand Berthoud today, we would like you to discover – or re-discover – who Ferdinand Berthoud was in a previous video report we did. He is part of a “little club” of very important watchmakers that had a real influence on the art and science of watchmaking during the late eighteenth and early nineteenth centuries. His specialty was marine chronometers or, put another way, precision.
This history has placed the bar rather high for the development of the first watch paying tribute to the illustrious name, and the team of Karl-Friedrich Scheufele has pulled it off very nicely with the development of a spectacular and architectural movement. This caliber uses the intricate chain and fusée mechanism for releasing energy stored in its spring barrel, an element typical of marine chronometers of the time. Furthermore, this watch’s escapement consists of a very large tourbillon beating at 3Hz and high-precision direct drive seconds, which can be admired from the case-back. This watch has a power reserve of 53 hours with an indicator on the dial side.
When it comes to its design, this watch has a lot of personality. Here again the idea was to link it with the world of marine chronometers and very specifically to some watches designed at the time by Berthoud himself. In addition to its octagonal shape, one of the original aspects of the case is the small windows on the side that allows the observer to see and enjoy inner workings of the movement – like the chain and fusée.
The FB1 comes in two versions: housed in white gold or rose gold.
