RM 11-03 AUTOMATIC
AUTOMATIC WINDING FLYBACK CHRONOGRAPH MCLAREN
UNREMITTING R&D EFFORTS
These highly sophisticated calibres, which are always record-breaking marvels of technical prowess and manifestations of modernity in every aspect of their realisation, are constantly redefining tomorrow’s horology.
Richard Mille and McLaren Automotive released their first jointly-commissioned timepiece, the RM 11-03 Automatic Flyback Chronograph McLaren, at the 2018 Geneva International Motor Show. Limited to 500 pieces worldwide, McLaren customers have the opportunity to match their edition number of 1 to 500 of their McLaren Ultimate Series to the caseback number of their RM 11-03 McLaren.
Precocious both as a driver and an engineer, Bruce McLaren became, at 22, the youngest driver ever to win a Formula 1 Grand Prix, in 1959.
His record was toppled only 44 years later, by Fernando Alonso.
However, the New Zealand-born constructor’s career apotheosis was to come at the 1968 Belgian Grand Prix, where he took first place in a car bearing his name.
After this first McLaren Formula 1 victory, Bruce set his sights on the world title, but his thoughts were mostly of a sports car that could compete with the reigning monarchs of the road from Ferrari, Aston Martin and Jaguar. In the spring of 1970, Bruce McLaren was the victim of a fatal crash on the Goodwood Circuit during trials of one of his prototypes.
Despite this tragedy, the team that bears his name survived. Not only that, but the South African engineer Gordon Murray, would, with the help of thirty or so technicians, finally realise the ambition of the brand’s creator in 1993, designing the first ever McLaren road car, produced in an edition of just over a hundred cars. This was the car that ushered in a dynasty of prestigious Supercars of which the McLaren Speedtail is the latest scion.
WORDS OF ROB MELVILLE, McLaren Automotive's Head Designer
Skeletonised, automatic winding movement with a variable-geometry rotor, offering hours, minutes, seconds, flyback chronograph, 60-minute countdown timer at 9 o’clock, 12-hour totaliser, oversize date and month indicator. Limited edition of 500 pieces
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautical and automobile industries.
The baseplate of the RMAC3 calibre has been optimised to achieve an extremely low weight/resistance ratio.
The skeletonised baseplate and the bridges were subjected to separate and extensive validation tests to ensure they met rigorous strength requirements.
OVERSIZE DATE DISPLAY
• 18K white gold weight segment
• Weight segment with 6 possible positions adjusted by screws in grade 5 titanium
• 18K white gold wings
• Ceramic ball bearings
• Unidirectional anti-clockwise winding
This exclusive Richard Mille design makes it possible to effectively adapt rewinding of the mainspring to the user’s activity level, in sporting or non-sporting environments. By adjusting the six-position rib, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or to slow it down during sporting activities.

RM 11-03 McLAREN, RICHARD MILLE'S TAKE ON THE GRAN TURISMO
CASE IN CARBON TPT ® AND ORANGE QUARTZ TPT ®
The tripartite case of the RM 11-03 is water resistant to 50 metres, ensured by two Nitrile O-ring seals. The case is assembled using 20 spline screws in grade 5 titanium and abrasion resistant washers made of 316L stainless steel.
TITANIUM CROWN AND PUSHERS
• Hand-polished locking sections
• Burnished pivots
• Diamond-polished sinks
• Pinions with undercuts
• Chamfered and polished by hand
• Screw slot and screws bevelled and polished for a rounded, polished tip
• Diamond-polished angles
• Circular-finished faces
• Rhodium plating (before cutting the teeth)
• Minimal corrections applied to the wheels in order to preserve geometry and performance
FREE-SPRUNG BALANCE WITH VARIABLE INERTIA
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to the screws during assembly. These screws are unaffected by physical manipulation during assembly or disassembly and age well.
