A WATCH FOR THE SEVEN SEAS
Automatic winding movement with hours, minutes, running seconds at 3 o’clock, oversize date, month, annual calendar, flyback chronograph with central seconds counter and 60-minute countdown timer at 9 o’clock, 24-hour totaliser at 6 o’clock, UTC function and variable-geometry rotor.
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
These components, crafted of grade 5 titanium with black PVD coating, confer great rigidity on the whole assembly, as well as the precise surface flatness essential for perfect functioning of the gear train.
The skeletonised baseplate and bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
Semi-instantaneous with automatic adjustment for months of 30 or 31 days, the oversize date is placed in a red-outlined horizontal aperture under 12 o’clock, while the month sits between 4 and 5 o’clock.
The Richard Mille RM 60-01 uses variable geometry to optimise the rotor’s winding motion.
• Arm in grade 5 titanium
• 18K white gold weight segment
• Weight segment with 6 possible positions adjusted by screws in grade 5 titanium
• 18K white gold wings, high palladium content
• Ceramic ball bearings
• Unidirectional; anti-clockwise winding direction
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.
EIGHT-POINT AND SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

BIDIRECTIONAL BEZEL WITH COMPASS SEGMENTS
The RM 60-01 was conceived to allow navigators to orientate themselves at sea, thanks to the rotating bezel featuring the display of the four cardinal points, a measuring disc of 360° and a 24-hour scale.
What differentiates the RM 60-01 from the other ‘regatta’ watches is that it can be used for orientation in both the Northern and the Southern Hemispheres without any additional calculation, simply by selecting the appropriate scale.
