Richard Mille watches are modern-day classics among luxury timepieces; tonneau-shaped marvels feted for their innovation in design, materials and movements. The latest offering – the RM 72-01 Lifestyle In-House Chronograph – though less outwardly flashy than some models, is no different.

The brand’s first in-house flyback chronograph, it features a double-oscillating pinion mechanism that took a full 30 months to develop. Unsurprisingly, after such efforts, a patent is pending for the design.

“This pinion, which can enmesh or withdraw from the gear teeth, has been twinned. There’s now one for the minutes and another for seconds. This system is thinner than a vertical clutch, which would be hard to fit into the heart of the movement,” says Salvador Arbona, technical director for movements at Richard Mille.

The innovative double clutch has a double impact: keeping the Calibre CRMC1 slim at a willowy 6.05mm, despite it containing a whopping 425 components; and also meaning that the chronograph function has little impact on the watch’s power reserves.

That’s handy, considering the 24-hour and 60-minute counters positioned at 5 o’clock and 2 o’clock respectively that let you keep track of a long drive, or the time spent on a time-sensitive project.

One of the most striking features of the dial? The three counters are colour-coded – the blue accented one for seconds, the orange for minutes and the green for hours. As a visual counterbalance, the numbers 3, 8 and 11 are highlighted, creating an interesting asymmetry.

Other features include the baseplate and bridges crafted in grade 5 titanium, a highly corrosion-resistant and rigid alloy widely used in the aerospace and automotive industries of 90 per cent titanium, 6 per cent aluminium and 4 per cent vanadium.

The date is displayed in vertical fashion in a rectangular window at 7 o’clock, while at 3 o’clock is the function indicator, which can be compared to a gearbox in a car, displaying winding (W), date adjustment (D) or hand setting (H) when the crown is pulled out.

The RM 72-01 model is designed for everyday use and so has a 50-hour power reserve and is available in four different combinations – 5N red gold, titanium, and black or white ceramic.
