The RM 07-01 shines with its extreme mechanical perfection, it also shines with the sensual and curvaceous lines of its tonneau shaped case design and its dial with a gemstone set center field. Comfort has always been one of the brand’s top priorities. Many years of development and testing concerning the development of this strap has resulted in a very ergonomic ensemble that is a pleasure to wear.
The heart of this new timepiece centers on the novel, in house designed caliber CRMA2, a highly skeletonised automatic movement developed specifically for the RM 07-01.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA Guarantees greater reliability when subjected to shock and also during movement assembly and disassembly, hence better chronometric results over time. The regulator index has been eliminated, thus guaranteeing a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.
CALIBER CRMA2 Skeletonised automatic movement with hours, minutes and adjustable rotor geometry.
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.
