THE DIRECT DESCENDANT OF THE RM 039 AVIATION WATCH

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.

Main characteristics

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.

01
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.

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.

02
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.

POWER RESERVE Circa 50 hours (±10%). Actual power reserve results will depend on the period of time the chronograph is utilized.

03
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.

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.

CASE RM39-01

The case features a unique four-part structure. The system is completed by the incorporation of horns in the case as- sembly. The four-part case of the RM 39-01 is very difficult to make. After a turning operation lasting 1 hour and 40 minutes, no less than 800 milling operations are required, taking several hours. Machining demands nearly 11 hours of separate operations. It is followed by a meticulous quality control procedure that takes a full day for each case. The 3 pushers, their components and the crown of the RM 39-01 require 10 days of machining, during which they undergo numerous tests for water-resistance and quality control, followed by the manual brushing and polishing of the entire case. All of these stages are vital in producing the characteristic ergonomic quality of Richard Mille watches. To facilitate reading off altitude density, the RM 39-01 has a movable indicator at 8 o’clock incorporated into the pillar. This pillar is also equipped with a button, which raises the indicator up when pressed once. This ensures a more accurate read-out.

BIDIRECTIONAL BEZEL WITH E6-B SLIDE RULE

Rotating bezel The yellow transfers show a logarithmic scale (from 10 to 99) and the units of measurement, in red, can be used to convert the measurements used in aeronautics. Equivalents can thus be found between kilometers (KM), nautical miles (NAUT) and statute miles (STAT), or between liters (Liters), US gallons (US GAL) and imperial gallons (IMP GAL). Meters (Meters) can also be converted into feet (FT), and kilograms (KG) into pounds (LBS) and vice versa. The indications shown in yellow on the outside at 3 o’clock enable the air temperature to be selected from -60°C to +50°C. This is essential for calculating real altitude in flight in relation to temperature. An altitude scale is provided via a green transfer on the outside of the bezel at 9 o’clock. It is expressed in thousands of feet, from 0 to 50. The same scale is visible on the outside (orange trans- fer) at 12 o'clock, but graduated in this case from -10 to +45. Using these two scales on the outside of the bezel combined with the slide rule enable real flight speed to be calculated in relation to air temperature and altitude.

FIXED BEZEL

A second logarithmic scale (from 10 to 99) can be used to read off conversions of units of measurement. It also has an hour scale from 1 o’clock (rate 60) to 9 o’clock. This scale can be used to solve any proble
