DESCRIPTION
Richard Mille Red Skull RM 52-01: $1,413,040 RM 52-01 Tourbillon Skull Following in the footsteps of the RM 052, this is the second piece in the Skull collection launched in 2013, and features the skull design that has come to symbolise the Richard Mille brand. This model stands out both for its choice of materials and the way it is crafted. Limited edition of 30 timepieces in TZP ceramic and carbon nanotubes. An iconic concept Following in the footsteps of the RM 052, this is the second piece in the Skull collection launched in 2013, and features the skull design that has come to symbolise the Richard Mille brand. This model stands out both for its choice of materials and the way it is crafted. Manual winding tourbillon movement with hours and minutes. TZP was chosen for the RM 52-01’s bezel and case back. This low-density material (6g/cm3) is highly scratch-resistant and has a low thermal conductivity coefficient. Made from 95% yttrium-stabilised zirconium, TZP has a pronounced grain that provides the perfect finish. The bezel and case back can therefore be microblasted and the corners hand-polished. For the case middle, Richard Mille decided to use carbon nanotubes for their proven ability to protect the tourbillon movement nestled in the centre against impacts. Bonded to a black polymer, the carbon nanotubes case middle helps to reduce the watch’s weight. The RM 52-01 case is water resistant to 50 metres. It is assembled using an average of 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel. The upper and lower jaws hold the jewel of the tourbillon carriage. The “Jolly Roger” comes to life thanks to the 4 bridges that link the movement to the case. The skeletonised baseplate and bridges have been subjected to comprehensive testing in order to optimise their resistance capacities. Spline screws in grade 5 titanium for bridges These screws enable better control of the torque applied to the screws during assembly. Hardly affected by physical manipulations during assembly and disassembly, they also age well. Fast rotating barrel (6 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 and performance is thus enhanced, It provides an excellent mainspring delta curve. The choice was determined by the ideal power-reserve/ performance/regularity ratio.Power reserve RM 52-01 Torque limiting crown This additional security system prevents from accidental overwinding, which could cause damage to the winding stem or putting extreme pressure on the mainspring barrel. undefined Finishing Movement Hand-polished bevelling Microblasted milled sections Drawn or polished outer faces Steel parts Microblasted surfaces Satin-brushed surfaces Hand-polished bevelling Long strokes Matt ”brouillé“ strokes Long strokes on the sides Polished sinks Profile-turning Lapped and polished ends Burnished pivots Wheels Diamond-polished sinks Circular decorations on the front surfaces Rhodium-plating (before the teeth are cut). Minimal corrections are made to the wheels to preserve their geometry and overall performance. RM 52-01 Technical Sheet Main features Variable inertia, free sprung balance A free sprung balance with variable inertia and a terminal-curve spring guarantees greater reliability in the event of impacts and during movement assembly and disassembly. It also guarantees better chronometric results over an extended period of time. The index is eliminated, thereby allowing a more precise and repeatable adjustment using 4 setting screws. Barrel pawl with progressive recoil This device offers significant winding gain (approx. 20%), especially at the start of winding. It also ensures an ideal distribution of the mainspring’s internal tension. Winding barrel teeth and third-wheel with central involute profile The central involute profile of the winding barrel teeth provides an optimal pressure angle of 20°, which promotes effective rotary motion and compensates for possible variations in the operation of the going train. This, in turn, ensures excellent torque transmission and a distinct improvement in performance. Other features Movement dimensions: 32.80 mm x 30.90 mm Thickness: 6.87 mm Tourbillon diameter: 10.90 mm Balance wheel diameter: 9.12 mm Number of jewels: 19 Balance wheel: Glucydur, 2 arms, 4 adjustment screws Moment of inertia: 11.50 mg.cm2, angle of lift 53° Frequency: 21,600 vph (3 Hz) Balance spring: in ELINVAR by Nivarox® Shock protection: KIF ELASTOR by KE 160 B28 Barrel arbor: in nickel-free Chronifer (DIN x 46 Cr13 + S), with the following characteristics: stainless, non-magnetic, tempered.
