Eye Candy: RM 40-01 automatic tourbillon McLaren Speedtail equipped with CRMT4 movement Richard Mille RM 40-01 at a price of millions of dollars
The brand new Richard Mille RM 40-01 automatic tourbillon McLaren Speedtail was released yesterday, which is the assembly process of its impressive caliber CRMT4. The movement is a self-winding tourbillon movement with hours, minutes, variable geometry rotor, oversized date, power reserve indicator and function selector. The new automatic movement architecture requires a staggering 8,600 hours of development time, most of which is used to finalize the extremely high level of detail. Grade 5 titanium has been used for key components such as bridges, bridge screws, base plates and rotor cores.
The CRMT4 movement introduces a power reserve display and a large date and function selector function, all of which are hot Richard Mille‘s first innovations on the internal tourbillon. The wheels are machined with the McLaren logo decorated with the Speedtail hood, while the arched parts have new surface contours that are necessary to translate the curve of the car. The movement measures 30.48 mm x 35.35 mm x 6.81 mm, includes 37 jewels, and is equipped with a free spring balance wheel with variable inertia. This balance wheel represents the ultimate goal of innovation. It guarantees higher reliability when subjected to shocks and during assembly or disassembly of the movement. Therefore, as time goes by, the timing is better. The regulator index is eliminated, and because of the four small adjustable weights directly on the balance, more accurate and repeatable calibrations can be performed.
The casing ring is no longer used, and the movement is installed on the chassis mounting rubber (ISO SW) fixed by titanium screws. The variable geometry rotor is the symbol of Richard Mille timepieces. It has a platinum oscillating weight with a core made of grade 5 titanium and a center of gravity made of red gold. The platinum and red gold winding rotors are inspired by the hood of McLaren Speedtail, while the top cover of the roof is the setting of the barrel. The guide rail is black PVD treated metal, with ceramic ball bearings, and has a Oneway automatic winding device.
Through this variable geometry rotor, the clockwork function can be adjusted to the owner’s activity level. Adjust the weight, slide it sideways to the correct position, and fix it in place with two spline screws to change the setting. When the weight is close to the outer edge, the inertia of the movement is best, so the barrel retreats faster. If the weight is placed in the center of the rotor, the inertia will decrease and the winding speed of the barrel will be slower.
Richard Mile RM 40-01 automatic tourbillon McLaren Speedtail can be summarized into five developed prototypes, 8,600 hours of development of the movement structure, 672 components, 5000 g shock absorption test and 18 months of development of the new case shape . Every component of the movement is exquisitely crafted, including hand-polished patterns, hand-polished bevels, micro-jet milling cut surfaces, micro-jet water tanks, PVD treatment of bridges, and plasma treatment of the bottom plate.
The whole operation process of the Wholesale Fake watches is the main power transmitter of the whole movement, and its gear teeth adopt a special contour to ensure a pressure angle of 20 degrees. This system eliminates possible differences between the centers of each wheel caused by thermal changes and normal use, and promotes the smooth transmission of torque to the balance wheel, thereby supporting excellent timing results. In addition, the use of grade 5 titanium spline screws on the bridge and housing can better control the torque applied to the screws during the assembly process. These screws are not affected by physical operations during assembly or disassembly and are well aged.
