Richard Mille, RM 015 collection
| Model: | RM 015 PERINI NAVI CUP |
| Ref.: | 515.48.91 |
| Description: | Inspired by the world renowned and extraordinary sailing vessels created by the yacht builders Perini Navi of Viareggio, Italy, the RM 015 echoes the visual elements and nautical details found on these luxurious craft. The shapes of the crown and the case outlines, the tourbillon and winding barrel bridges, the titanium screws of the case and movement, as well as many other elements are directly inspired by details found on the ocean going vessels created by Perini Navi. MARINE CALIBER RM015: Manual winding tourbillon movement with hours, minutes, second time zone, power reserve indicator, torque indicator and function selector. Dimensions: Length 48 mm x 39.30 mm (widest point) x 13.84 mm (thickest area) MAIN FEATURES (MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS) CARBON NANOFIBER MOVEMENT PLATE A composite material of carbon nanofibers, that becomes an isotrope possessing mechanical, physical and chemical stability when molded under high pressure. The movement plate has a ribbed perimeter that assures better rigidity between the plate and bridges. This carbon composite structure is also amorphous, chemically neutral and dimensionally stable within a wide range of temperatures. POWER RESERVE: circa 75 hours (indicated on the numeric scale positionned between 1 and 2 o’clock). TORQUE INDICATOR Shows the mainspring tension and enables the movement timing to be optimized. Below 53 dNmm, the spring is too slack; at the other extreme, above 65 dNmm, excessive tension can adversely affect the running of the movement and may even cause damage. (These indications appear on the numeric scale positionned between 2 and 4 o’clock). SECOND TIME ZONE INDICATOR Indicates a second time zone with numbers on a transparent sapphire crystal disc. These come into view when suspended above the light colored field near 10:30. The second time zone is simple to adjust via a pusher located at 9 o’clock. VARIABLE INERTIA, FREE SPRUNG BALANCE The free-sprung balance gives better reliability in the event of shocks, allows for efficient movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time. FAST ROTATING BARREL (6 hours per revolution instead of 7,5) 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 ratio. OTHER FEATURES MOVEMENT DIMENSIONS: 30.20 x 28.60 mm THICKNESS: 6.35 mm TOURBILLON DIAMETER: 12.30 mm BALANCE WHEEL DIAMETER: 10 mm NUMBER OF JEWELS: 23 BALANCE: GLUCYDUR, 2 arms, 18 setting screws, inertia moment 10 mg cm2, angle of lift 53º FREQUENCY: 21,600 vph (3 Hz) BALANCE SPRING: ELINVAR by NIVAROX TORQUE INDICATOR with reference measurement in dNmm SHOCK PROTECTION: KIF ELASTOR KE 160 B28 JEWELS set in white gold chatons BARREL SHAFT in nickel-free chronifer (DIN x 46 Cr 13 + S), with the following characteristics: stainless - antimagnetic - suitable for tempering. |
