Held every two years, the Le Mans Classic is a classic car event where pre-1979 automobiles that have competed at Le Mans are once again allowed around the track. Title sponsor and official timekeeper Richard Mille has created a limited edition timepiece for the 2014 event, creating another version of its RM030 automatic, this time in green and white to match the official colours of the Le Mans Classic.

In typical Richard Mille style the case is comprised of three layers: ATZ ceramic for the front and back plates of the case, with the case middle in titanium Aluminium-toughened zirconia (ATZ) is a composite material of aluminium particles inside a zirconia matrix that is strong, rigid and resistant to corrosion.

The RM030 Le Mans Classic has an automatic movement developed by Vaucher, featuring a power reserve indicator at nine o’clock and a 24-hour hand at two. A noteworthy though not groundbreaking feature is the winding mechanism that disengages once the mainspring reaches 50 hours of power reserve. When the power reserve drops to 40 hours the rotor re-engages and starts winding once again. An indicator at 12 o’clock indicates if the winding mechanism is on or off.

The RM030 Le Mans Classic 2014 is limited to 100 pieces with a yet to be announced retail price. With other versions of the RM030 averaging US$100,000, expect this to cost the same, or more.
