Sylvain Pinaud Monopoussoir Chronograph

Sylvain Pinaud is an independent watchmaker based in the small town of Ste-Croix, on the Jura Mountains.

During Basel-world 2019, Sylvain Pinaud presented the Monopoussoir Chronograph, a unique piece created during one year and which allowed him to be laureate of the contest « Un des Meilleurs Ouvriers de France ».

The watch houses a highly customized ETA 6497 mechanical manual wound movement. From the movement, only the gear and the escapement are preserved. The rest: bridge, main plate, winding system and balance wheel are completely rebuilt and manufactured to fully integrate the chronograph.

The choice of a traditional operation, namely horizontal clutch and column wheel, is for the watchmaker an evidence given that it’s beautiful, simple and effective. The delicate functions, as well others with strong constraints have ruby bearings. Each spring, jumper or lever is designed to harmonize with the whole and ensure optimal operation.

In its aesthetics side, each detail of the watch is highlighted and each curve is enhanced. The dressing was conceived around the chronograph. The peripheral sapphire crystal makes it possible to observe it from a new angle. The case, of a simple design, machined in a grade 5 titanium block plays on contrasts between brushed and polished bevellings. The caseback, the watchmaker wished it sober, revealing only the balance wheel and its bridge in the manner of marine chronometers.

The timepiece must respect anonymity for the contest; therefore no engraving appears on it. For the next manufactured chronographs, the words “Sylvain Pinaud Horloger”, “monopoussoir chronograph” as well as the number of the piece and the year will appear on the caseback. On the front face, will only appear soberly “Sylvain Pinaud” on the dial.

In this prototype, a few parts were manufactured by CNC, the vast majority were handmade and with conventional machines. Tempering, bluing, decoration and polishing, all this is entirely done in the traditional way.

The chronograph is layed out in a wide opening allowing to observe the different sequences. The shape of the components is directly related to the conventional manufacturing methods, each component must be able to be made without CNC, by a watchmaker.

All of the steels are mirror-polished and bevellings by hand. The wheels are also bevellings and circled. Different surface finish and galvanic processing are combined to accentuate contrast and depth: The anthracite gray and grained mainplate, the upper bridge straight line to contrast with the grained dial.

The piece is customizable, especially dials and rhodium colors. Finally, the presented watch is a prototype, some small adjustments and small modifications are planned on the models to be produced, for instance the crown a little long, and the contrast of the minute counter to be accentuated. Because of the craftsmanship and the great degree of finishing, a very limited quantity of numbered watches will be produced.
