This split seconds chronograph, another new caliber for the brand, unites all the experience acquired in the fields of reliability, accuracy since the brand’s inception. In this ultimate split seconds chronograph, having successfully managed to make the optimised performance of every function completely reliable and repeatable under all conditions. Our storehouse of on-the-ground experience gained with our sporting partners under extreme conditions was exceedingly useful in the development of this creation. Limited edition of 10 pieces in carbon nanotubes.
The RMCC1 movement is inspired by the tourbillon caliber with split-seconds chronograph from the RM 008. Released in 2004, this caliber has established itself as one of the most complex in the world thanks to its tourbillon movement operating a split-seconds chronograph.
TORQUE INDICATOR Supplies information about the mainspring’s tension, thus permitting the optimalization of the chronometric functioning of the movement. Below 53 dNmm, the spring is considered to be too slack, while above 65 dNmm, the excessive spring tension can adversely affect the mechanism’s operation, or else actually endanger it. (These indications appear on the numerical zone to the right of the barrel).
FUNCTION INDICATOR In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand setting positions as the crown is pulled out. Each position is indicated via a hand at 4 o’clock displaying the following functions: W (Winding) – N (Neutral) – H (Hands).
SKELETONIZED TITANIUM BASEPLATE Finished in grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% titanium, 6% aluminium and 4% vanadium. This combination further increases its mechanical properties, which explains its frequent use in the aerospace, aeronautical and automobile industries. The baseplate of the calibre RMCC1 has been optimised to achieve an extreme weight/resistance ratio.
CALIBER RMCC1 Manual winding tourbillon movement with hours, minutes, split-seconds chronograph and power reserve, torque and function indicators.
BALANCE WHEEL WITH VARIABLE INERTIA
This type of balance wheel, which represents the ultimate in innovation, guarantees greater reliability when subjected to shock and also during assembly and dismantling of the movement, thus achieving better chronometric results over time. The index is eliminated, thereby allowing a more precise and repeatable adjustment using 4 setting screws.
FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours)
This type of barrel provides 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
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding. It also aids in the even distribution of the mainspring’s internal tension.
WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The wheel with a central developing profile and a pressure angle of 20° promotes rolling movement more effectively, compensates differences between centers, ensures excellent torque transmission and a distinct improvement in performance.
MODULAR TIME SETTING MECHANISM FITTED AGAINST THE CASE BACK
Provides the following advantages for longevity and maintenance: - Since the component is mounted outside of the movement, the time setting assembly can be changed
without affecting the integrity of the baseplate in the event of a possible defect or during maintenance, - The mounting and dismantling of this module from the back will not require the removal of the hands and the dial.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
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.
EXTREME FINISHING FOR THE MOVEMENT
Watchmaking expertise can be found throughout the caliber RMCC1, with drawn, polished, satin finished and soft polished surfaces all created by hand. For example, take the complex shape of the tourbillon and barrel bridges in microblasted stainless steel with their visible and non-visible areas that are completely soft polished. Other parts, such as the barrel drum, the minute wheel and the small and large medium wheel are circular grained both above and below then hand-beveled and rhodium plated before the teeth are cut. The various yokes of the caliber RMCC1 are straight-grained, sanded on both sides and soft polished. This range of finishes also provides technical solutions to optimize the Chrono Competition movement.
- Hand-polished bevelling
- Hand-polished locking-sections
- Microblasted milled sections
- Lapped and polished contact points
- Burnished pivots
- Wire-drawn and microblasted surfaces
- Hand-polished beveling
- Concave chamfering with a diamond tool
- Circular-decorated faces
- Gilding (before cutting the teeth)
- Minimal corrections to preserve the geometry of the wheels and their performance
