Cyril Brivet-Naudot is part of the new wave of independent watchmakers. Born in France, he learned the craft at the Lyceé Edgar Faure in Morteau, France, and then continued his education at the École Polytechnique Federal in Lausanne. In making his own watches, he drew inspiration from the legendary watchmakers of the past, who produced outstanding timepieces long before the invention of modern methods of metalworking. That's why Cyril Brivet-Naudot explains that he makes his watches himself, without the involvement of subcontractors, without the use of CNC and other state-of-the-art computer-controlled equipment - on traditional machines with traditional tools and mostly by hand. The uniqueness of his watches lies in the fact that only the mainspring, the balance spring and, to some extent, the jewels are bought in, while all other parts of the caliber and the watch case are made by him.
He began developing the Eccentricity, his first watch, around 2015 and presented the first examples at Baselworld as early as 2019. In designing the caliber and watches in general, he didn't follow the beaten path. The watch is truly unusual and even eccentric, and in this sense the name of the watch should be recognized as appropriate for its design and technical characteristics.
In addition to the unusual design, in which we find a combination of obvious craftsmanship, a modern laconic appearance with typical features of early 19th century calibers, complemented by a free arrangement of the movement with a spectacular version of the échappement libre excentrique as well as a balance set on the dial.
The movement has architecture found on rare early 19th century timepieces, with the balance on the dial. On the back of the movement, you can see the trapezoidal bridges, which were very popular in that period. Another indication of this is the caliber, which is key-wound and key-set. This is extremely rare in modern wristwatches. The use of a key wind and key set simplifies the caliber, which is more than made up for by the use of the unusual échappement libre excentrique, originally invented by Louis Richard in 1860 and adapted by Cyril Brivet-Naudot and Luc Monnet, his cooperating watchmaker. The escapement can be seen on the back of the movement, and its function is also spectacular.
The watch is mostly handmade by the master, which can be seen by the freely engraved inscriptions on the rim of the caseback and on the movement plate, both on the dial side and on the back. This makes the present example even more valuable. In addition, this watch has a special status, as it's a unique prototype, in which the master worked out the design with a separate bar to attach the outer coil of the Breguet hairspring. Currently, only one timepiece with such a feature is known - this is the present lot.
