Richard Mille (Richard Mille) introduced the latest ultra-light RAFA timepiece, its visual system and function are similar to the strings of a tennis racket, using a steel cable system.
Launch of the RM 27-04 tourbillon Rafael Nadal, which is designed to withstand an acceleration of 12,000 Gs, which is the highest record for a Richard Mille timepiece.
In general, the weight of the RM 27-04 is 30 grams-the weight is not as good as the original Rafael Nadal RM 027 watches of 19 grams, and a ten-year partnership has begun-but compared to the average mechanical watch In other words, its weight is still incredible and the average weight is close to 100 grams.
In order to achieve such excellent lightness and strength, the case is composed of 38.40 mm wide and 11.40 mm (47.25 mm lugs to lugs). The case is made of a new material specially made for watches. This watch combines carbon fiber and Polyamide.
This watch only provides hours, minutes and tourbillon, and the design goal of this tourbillon is to withstand the impact of 12,000 Gs, which makes the manufacturing process very complicated.
As with Nadal luxury watches in the past, the manually wound movement is crucial because the automatic rotor may be damaged by force when playing tennis, especially at a professional level.
What’s impressive is that the movement is fully supported by a microspray screen measuring only 855 square millimeters, composed of a braided steel cable with a diameter of 0.27 mm, and fixed by two tensioners of 5N gold treated with PVD. In place. This structure is unprecedented in the watchmaking industry.
“Inspired by the same principles as tennis racket strings, the watchmaker anchored the steel cable to the tensioner at 5 o’clock and then started making the grid, tying each main string together before adding the cross strings. Braided above and below the main string, the cable is passed through a hollow baffle made of grade 5 titanium, passed 38 times, and then sorted in a tensioner at 10 o’clock. The movement is positioned diagonally through Five grade 5 polished titanium metal hooks are connected to the mesh. These titanium alloy hooks extend from the back of the base plate and have a 5N gold PVD coating. watches swiss
In addition to the cable system and composite housing, the main board and bridges are also made of grade 5 titanium (90% titanium, 6% aluminum and 4% vanadium) to help minimize weight.
The movement dimensions are 32.75 mm x 28.95 mm and the thickness is 5.85 mm. The free-hanging balance wheel has a diameter of 10 mm, and the tourbillon is 12.30 mm. The movement beats at a frequency of 3 Hz, uses 19 jewels, and has a fairly low power reserve of 38 hours-but in order to concentrate all the energy on making the movement extremely lightweight and durable, this is a sacrifice.
The waterproof rating is 50 meters. This will be limited to 50 pieces. “RAFAEL NADAL” and the version number XX/50 are engraved on the bottom cover. “RAFA” is engraved on the side of the case on the side of the crown.
The RM 27-04 Tourbillon watch was worn on Nadal’s wrist during the French Open (that is, now) and will be worn in all future tennis matches until another watch is created.
