In order to make space for the winding system with its variable- geometry rotor, we enlarged the case of the RM 004 and RM 008 significantly to create this new model of chronograph, an automatic version of its predecessors. Taking a radical architectural concept and 3D mechanical aspect — both characteristic of the brand — to the limit. It was the skeletonised, pared-down structure of the mechanism that enabled us to showcase this aesthetic. We enhanced the ergonomics through grooved, non-slip push-pieces. The concave grooves of the crown also helped to accentuate the tension in the use of space defined by the watchcase. Each component comprises the aesthetic expression of its functionality. A complex model, famed for its use by renowned sportsmen.
Rotor with variable geometry. 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 and personalized to the owner’s lifestyle.
OVERSIZE DATE DISPLAY Semi-instantaneous, placed in a red outlined horizontal aperture under 12 o’clock.
MONTH DISPLAY Semi-instantaneous indicate with Arabic numerals, placed between 4 and 5 o’clock.
ANNUAL CALENDAR Automatic adjustment for months of 30 or 31 days.
CALIBER RMAC1 Skeletonised automatic winding movement with adjustable rotor geometry offering hours, minutes, seconds, flyback chronograph, 60-minute countdown timer, 12-hour totalizer, oversize date, month.
DOUBLE BARREL SYSTEM
The double barrel system helps to improve the torque stability over a longer period. This is achieved by dividing the stored energy within two winding barrels instead of one, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks 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 adjustable weights located directly on the balance.
