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 specifically for the caliber CRMA1, the wheels use a 20° pressure angle. This system equalizes any discrepancies that might arise between the centers of each wheel, for instance during thermal changes and normal use, 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.
