Richard Mille RM 65-01 McLaren W1

The Richard Mille RM 65-01 McLaren W1 has a split-seconds chronograph with a 30-minute counter at 3 o'clock. A 12-hour counter sits at 9 o'clock, while hours, minutes, seconds at 6 o'clock and a date make up the time display. Skeletonised self-winding calibre RMAC4 has 51 jewels, runs at 5 Hz and offers a power reserve of around 60 hours. The baseplate and bridges use grade 5 titanium, and a variable-geometry rotor has a three-position weight. A 50 metre water-resistance rating applies to the tripartite case, which is assembled with 12 spline screws. The watch is a limited edition of 500 pieces.
