The Monopusher Chronograph
Sylvain Pinaud x Massena Lab
The chronographe monopoussoir is a hand wound monopusher chronograph, that indicate hours, minutes and seconds.
Its chronograph function gives you the record of seconds and minutes on a 45-minute register.
Its elegant and robust mechanism is housed in a 42 mm case in titanium, serving as a showcase for the mechanical parts.
The peripheral glass allows the movement to be observed from a new angle.
Every detail is brought to light, every curve highlighted and at every moment other subtleties are discovered.
The choice of a horizontal clutch and column wheel is obvious for the watchmaker because it is beautiful, simple and efficient.
Delicate functions, or others with strong constraints, have ruby bearings to guarantee optimal operation.
All finishing work is done by hand to achieve the highest possible level.
The wheels are circular brushed and beveled, the steel components are black polished and beveled.
The silver dials are grained and beveled by hand.
A thin perimeter circumscribing each counter dial reinforces their timeless elegance.
An exclusive chronograph, made with the highest crafstmanship. The movement, whose layout is inspired by marine chronometers, is revealed through an opening in the back, and its large chronometer balance beats calmly at 2.5 Hz.

The genesis of the Monopusher Chronograph
The result of an intense process of creation, craftsmanship and a lot of dreams.
Every four years, since its conception in 1924, the best artisanal craftsmen of France are eligible to compete for the title of “Un des Meilleurs Ouvriers de France” (MOF, “One of the Best Craftsmen of France”), a competition which dictates that only artisanal crafts can be utilised, so except for a very few parts, everything is done by hand.
As a challenge to create my very first watch, I enlisted with the monopusher chronograph, housed in a different case, which allowed me to be granted the MOF status in 2018, diploma of excellence that rewards my expertise.
Two unique pieces were born out of this great effort, and led to the inspiration for the collaboration with Massena Lab in a more contemporary case and the GPHG prize in 2024.
