The RM 017 tourbillon is the first rectangular case shape in the tourbillon range, continuing the development of the rectangular case first launched with the RM 016.
As with each Richard Mille watch, the RM 017 symbolizes the Haute Horlogerie values of both tradition and excellence. As a consequence the bridges, screws and even the hands are hand-finished.
With dimensions of 49.80 mm x 38.00 mm x 8.70 mm, the RM 017 extra flat tourbillon retains all the wrist fitting curvature and tapering towards 12 and 6 o'clock that every Richard Mille fan has come to expect.
The caliber RM017, with 23 jewels and beating at 3Hz, measures 31.20 mm x 29.45 mm while its thickness is only of 4.65 mm. As a consequence the RM 017's manual winding movement sets new standards as one of the thinnest tourbillon constructions ever created.
In addition, the RM 017 tourbillon uses a baseplate, bridges and balance cock created from ribbed, grade 5 titanium with a black PVD coating, thus providing the movement with great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train. The manufacturing of these titanium components is extremely time consuming due to the hardness of the material and the fact that titanium is flammable during processing thus requiring additional safety precautions during manufacture. The baseplate and all titanium parts of this extra flat tourbillon design have been subjected to separate and extensive validation tests to insure optimal strength requirements.
The function indicator of the RM 017 also continues Richard Mille's passion for mechanical innovation.
This concept, based upon a car's gearbox, offers the selection of three possibilities as the crown is pulled outwards: Winding (W), Neutral (N) and Handsetting (H). With this special gear system, stressful forces placed upon the crown are minimized, and any possible interference of the crown's functions with the movement is made impossible. This efficient gear system is further extended via a safety system with blocking gear and a torque limiting crown to prevent any possibility of the extra flat, manual winding movement of being damaged by over winding.
The RM 017 portrays the current collection's themes of motor sport and sailing, reflected in sleek, discreet lines that are among the thinnest of the collection.
The case represents an uncompromising approach, with extensive attention to all details of the case design with numerous stamping and machining operations required for the three main components (front bezel, back bezel and caseband). More than 18 days of machine adjustment are required and more than 400 hours of technical research and drawing before production can begin.
Each case requires 202 separate machining operations. The case of the RM 017 requires 39 swaging operations including 16 striking, 270 milling operations. The machining lasts 4 hours and 15 minutes. Concerning the finishing work, 1 day is needed for grinding, glazing and polishing.
The design and execution of this watchcase typifies the complete holistic approach to all parts of the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications. For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws.
The tripartite case is water resistant to 30 meters, ensured by two Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.
Cutting edge technology combined with elegance, exceptional lines, useful functionality and unmistakable personality, the RM 017 extra flat tourbillon typifies everything that Richard Mille Watches stands for.
Richard Mille did not simply try to find his place in the watchmaking world – he carved one out for himself, constantly striving not to take anything for granted, and to make innovation and extreme technical prowess his driving forces.Find out more >
