Horological Machine N°1 is a highly innovative and totally original timepiece. HM1 features the world’s first movement with four barrels connected in both parallel and series, as well as the first wristwatch movement to have the energy transmitted to the regulating system from two sources simultaneously.

The three-dimensionality of the case and the sophisticated multi-strata of the dial both captivate the eye and challenge the mind. Within that structure beats a movement like no other: 376 parts, 81 functional jewels, 4 mainspring barrels, 7-day power reserve and an elevated central tourbillon.

Look deeper and you will discover that Horological Machine N°1 is more than a meticulously hand-crafted work of art, more than an intricate masterpiece of micro-engineering: it is a machine epitomizing the incredible passion and enthusiasm its collective of Friends dedicated to its creation.
