With the RM 60-01 Regatta Flyback Chronograph, Richard Mille presents his first navigation technical watch. Using the RM 60-01 is based on two factors: knowledge of local time and the position of the sun. To calculate one’s location, the UTC indicator is directed towards the sun using the UTC pusher located at 9 o’clock and then the bezel is turned so that the UTC hand lines up with the actual local time engraved on the bezel’s circumference. When set in this manner, the compass headings North, South, East and West on the bezel will be correctly aligned with the actual direction on the Earth’s surface.
Powered by the grade 5 titanium RMAC2 caliber with its 55 hours of power reserve, variable- inertia balance, complete flyback chronograph functions, annual calendar with oversize date and UTC function, the RM 60-01 adds navigational capabilities thanks to its special rotating bezel with indications of the four cardinal points combined with a graduated 360° and a 24-hour scale disc.
CALIBER RMAC2 Automatic winding movement with hours, minutes, running seconds at 3 o’clock, oversize date, month, annual calendar, Flyback chronograph with central seconds counter, and 30 minute countdown timer at 9 o’clock, 24 hour totalizer at 6 o’clock, UTC function and adjustable rotor geometry.
BIDIRECTIONAL BEZEL WITH COMPASS Conceived to allow navigators to orient 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. Its functioning principle relies on 2 factors: the knowledge of the local time and the position of the sun in the sky. First, the UTC hand is placed pointing towards the sun. Then the rotating bezel just needs to be set in order for the UTC hand to indicate the local hour displayed on the bezel. North, East, South and West are then shown to the user. 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 calculation, simply by selecting the appropriate scale.
COUNTDOWN Located at 9 o’clock, the hand is replaced by a skeletonised 60 minutes-marked disc. The pilot can read minutes elapsed but also remaining minutes.
UTC FUNCTION The RM 60-01 features a UTC hand that can be used either as a second time zone indicator or in combination with the sun and the rotating bezel to orientate the points of the compass. It can be easily adjusted using the pusher at 8 o’clock.
ROTOR WITH VARIABLE GEOMETRY
- Arm in grade 2 titanium
- Flange in grade 5 titanium
- 6-positional adjustment via grade 5 titanium screws
- Ribs in 18K white gold, high palladium content
- Weight segment in white gold
- Ceramic ball bearings
- Unidirectional anti-clockwise winding direction
This exclusive Richard Mille design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level. By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or slow it down when sporting activities are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized.
BASEPLATE, BRIDGES AND BALANCE COCK MADE OF GRADE 5 TITANIUM
These components are in grade 5 titanium with black PVD coating. This provides the whole assembly great rigidity, as well as precise surface flatness that is essential for the perfect functioning of the gear train.
DOUBLE BARREL SYSTEM
The double barrel system contributes to the torque stability over a longer period. This is achieved by using more rotations of the barrel, thereby reducing pressure and wear on the teeth, bearings and pivots, hence an improved long-term performance.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly, hence better chronometric results over time. The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
These screws offer better control of the torque applied during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
Circa 50 hours (±10%). Actual power reserve results will depend on the period of time the chronograph is utilized.
In order to avoid accidental actuation resulting from an error of manipulation, Richard Mille developed a secondary locking crown that is able to lock both pushers simultaneously with a simple turn.
The green and red indexes respectively show whether the locking mechanism is in operation or deactivated. This complex, innovative mechanism is exclusive to Richard Mille.
