An important moment in the history of Richard Mille, as with the RM 72-01 Lifestyle In-House Chronograph, they launch the brands' first chronograph with it made entirely in its workshops in the Swiss town of Les Breuleux. It is a technical masterpiece that comes with quite a few novel features. While it does feature a traditional column wheel, it lacks a vertical clutch. Instead, it uses two oscillating pinions to transfer power to the chronograph. This comes with considerable advantages. One of them is that even when the chronograph runs, it has hardly a negative effect on the overall power reserve. Secondly, does this construction also require much less space. The height of the RM 72-01 Lifestyle In-House Chronograph can, therefore, be kept under 12mm, at a very impressive 11.68mm.
