The new RM 39-01 provides pilots with a practical and rapid instrument for successively timing different durations in a number of directions. They can therefore receive departure signals issued by radio beacons without losing time or having to execute numerous operations on their watches.
The RM 39-01 is having an ultra-complex flyback caliber that contains no fewer than 1,000 components. The RM39-01 movement is designed as a flight navigation instrument. This highly technical and extremely sophisticated watch is a modern interpretation of a device that is essential for any experienced pilot: the E6B slide rule, invented in the 1930s in the United States by Lieutenant Philip Dalton.
UTC FUNCTION The RM 39-01 Aviation E6-B features the display of a second time zone by means of a hand filled with superluminova. It can be easily adjusted pressing the pusher at 8 o’clock.
POWER RESERVE Circa 50 hours (±10%). Actual power reserve results will depend on the period of time the chronograph is utilized.
OVERSIZE DATE DISPLAY Semi-instantaneous, it is horizontally placed beneath 12 o’clock and functions via two skeletonized calendar discs. The date can be easily corrected using the pusher located at 2 o’clock.
CALIBER RMAC2 Automatic winding movement with hours, minutes, seconds at 3 o’clock, oversize date, month, flyback chronograph with seconds counter at the center, minutes and countdown counters at 9 o’clock, hour counter at 6 o’clock, UTC function and adjustable rotor geometry.
BASEPLATE, BRIDGES AND BALANCE COCK MADE OF 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.
By using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism. This was originally developed for pilots in order to not waste time (and therefore accuracy) from stopping, resetting and starting the chronograph whilst crossing navigational point.
While the chronograph function is activated, the hours and minutes show up the elapsed time thanks to the counter at 6 and 9 o'clock, the seconds are indicated by the central hands.
The user can start or stop the chronograph function via the pusher located between 1 and 2 o’clock. The flyback function can be continuously reset by depressing the second pusher located between 4 and 5 o’clock.
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.
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.
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 adjus- table weights located directly on the balance.
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.
