FAST ROTATING BARREL (5 hours per revolution instead of 7.5 hours)
This type of barrel has the following advantages:
- The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance,
- Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
NEWLY DEVELOPED GEAR TEETH PROFILE
The entire going train of the watch, the primary transmitter of power throughout the movement, utilizes a special profile
for the teeth of the wheels. Developed for the caliber CRMA2, the wheels use a 20° pressure angle.
This system equalizes any discrepancies that might arise between the axles of each wheel, and promotes an excellent
transmission of torque to the balance wheel, thus supporting excellent chronometric characteristics.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE MOVEMENT
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected
by physical manipulation during assembly or disassembly and age well.

CASE
The design and execution of the watch demonstrates a complete conceptual approach to the movement, case and dial. As
a result, everything has been constructed according to an extremely rigorous specifications and in complete harmony. For
example, the casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by
2 titanium screws. Features such as these are evidence of uncompromising workmanship. The caliber CRMA2 is highlighted
by the combination of unique materials such as red gold for the caseband and white ceramic for the bezel and the
caseback. It is particularly resistant to knocks and scratches and undergoes a long production process which results in a
final matt surface finish. The caseband is in satin 5N red gold with polished pillars.
The RM 07-01 is available in TPZ-Z brown ceramic, in ATZ white ceramic and in white or red gold.
The three-part case is water resistant to 50 meters ensured by 2 Nitril O-ring seals. The case is assembled with 12 grade 5
titanium spline screws and abrasion resistant washers in 316 L stainless steel.
