Richard Mille has today revealed the RM 65-01 McLaren Automatic Split-Seconds Chronograph W1, the fourth creation to emerge from its partnership with British luxury supercar and elite motorsports company, McLaren.

Richard Mille chose to power the RM 65-01 McLaren W1 with its most high-performance automatic chronograph movement, the RMAC4 that beats at an appropriately high speed of 5Hz or 36,000 vibrations per hour.



This high rate of oscillation enables the split-seconds chronograph calibre to record elapsed times down to just one tenth of a second, while the movement’s vertical clutch and the two six-column wheels ensure precise and ultra-smooth activation of the chronograph.

Also on the theme of speed, the RM 65-01 McLaren W1’s movement (which sits on chassis mounting rubbers instead of being secured by a conventional casing ring) features a ‘rapid winding’ system which enables the 60-hour power reserve to be fully recharged in little time using the special push piece made from orange Quartz TPT®.

And, in-keeping with McLaren’s "performance everywhere” principle ensuring that the W1 is the ultimate supercar, the RM 65-01 McLaren W1 is also perfect for daily use thanks to both the built-in robustness of the 480-part movement and its variable geometry winding rotor that can be adjusted to the wearer’s lifestyle. The view through the crystal enables the grey electroplasma treatment of the grade 5 titanium baseplate to be fully appreciated, along with the black PVD and grey electroplasma treated grade 5 titanium bridges.
