Based on the Lemania 2310, this present Roger Dubuis single button chronograph is an early example made before the brand's sale to Richemont. First and foremost a watchmaker, Roger Dubuis had tirelessly worked for brands such as Patek Philippe and Longines, before setting up his own workshop. It was in 1995 that Dubuis created his own brand, teaming up with Carlos Dias.

Originally made in a series of 28 examples, the H40 is a sight to behold and displays incredible details that would impress even the most fastidious watch purist. Firstly, the movement is based upon the Lemania 2310 ébauche - just like the famed Patek Philippe reference 5070. The movement proudly displays the Geneva seal - an exceptional feat for a small, at the time independent watchmaker. On top of that, it was certified by the Besançon Observatory. Finally, the dial itself is beautiful. Displaying Breguet numerals, feuille hands and a grené black dial, it is reminiscent of the vintage chronographs in the past, while displaying its own aesthetic flourishes.

The watch itself offers even more than just technical prowess and good looks - it represents a period of time, when now-household names such as F.P. Journe, Philippe Dufour and Roger Smith were experimenting, producing their very first prototypes, pushing the boundaries of watchmaking and re-defining the meaning of watchmaking. Industry veterans will look back at this golden period of horology as the cradle of Independent Watchmaking, with doses of both pride and nostalgia.
