Romain Gauthier began his professional life as a micro-mechanical engineer, but he could not deny that watchmaking was in his blood, as both of his parents had worked for manufactures such as Audemars Piguet, Lemania, and Dubois Dépraz. He launched his watch brand in 2005 with the Prestige HM, which was well-received by collectors, largely due to the exquisite movement finishing incorporating brushed and grained finishes with sharply hand-beveled edges. Indeed, no less a personage than Philippe Dufour himself inspired Gauthier not only to establish his own brand rather than a single timepiece, but encouraged him to push the envelope of craftsmanship.

In 2013, Romain Gauthier launched the Logical One, incorporating a 600-year old invention: the fusée-and-chain mechanism. By employing the fusée-and-chain in a wristwatch, Gauthier was able to provide constant force to the movement. Each link in the chain has a corresponding ruby to minimize friction, and most interestingly, the watch is not wound through the crown but through a button set in the case at nine o’clock.

Unlike many watchmaking brands, even among most independent watchmakers, Romain Gauthier creates the majority of his components in-house, even before assembling and finishing them – including such challenging components as hairsprings. In order to reveal these hard-fought innovations, the dial is openworked, and the time is displayed on an off-centered blue lacquered subdial, allowing the wearer to feast their eyes upon a bevy of traditional movement finishing techniques, assembled in a modern and avant-garde manner.

In 2021, Romain Gauthier announced that he would retire the Logical One, and issued a “Final Edition” Logical One that would only be produced in a series of twenty watches, and delivery would be taken by the 10-year anniversary of the Logical One in 2023. Numbered 3 of 20, the present watch is in close to new condition, complete with all accessories, ready for the next owner to enjoy.
