Greubel Forsey-Double tourbillon 30° fine ceramic technology
The actual double tourbillon 30° could be the first basic invention associated with Robert Greubel and Sophie Forsey in pursuit of extreme excellence. Greubel Forsey Double Tourbillon 30° Invention Piece 1 Vision
Shown at the Basel Watch Sensible in 2009. Seven years after, their double tourbillon 30° technology won the first award on Concours. The Intercontinental de Chronométrie set accurate documentation of 915 points (out of 1000 points) with the average timekeeping rate regarding 0. 3 to zero. 8 seconds per day over the competition.
The particular timepiece is housed in the blue ceramic case which is the latest interpretation of this distinctive creation.
Typically the Greubel Forsey double tourbillon 30° technology provides fantastic precision in ceramics due to a unique solution: in which the dog crate assembly with a smaller harmony and spring is turned at an angle of 30° any time rotating within four short minutes The inner angle of the parrot cage is relative to the first crate and completes a ring within 60 seconds. The 30° inclination angle combined with the distinct rotation speeds of the a pair of tourbillons improves timekeeping through averaging the position error a result of gravity in all usual see positions, especially in stable roles.

A number of coaxial barrels are linked with a spherical power reserve differential to provide a 120-hour chronograph reserve of power. The movement beats at the frequency of 3 Hz (21, 600 vibrations per hour).
Since the brdge, the hour and small rings, and the 4-minute tourbillon rotation indicator at some o'clock all use sky-blue crystal, the movement composition can be appreciated from both equally sides and as a whole.
The gold small moments and power reserve indicator have got a blue finish, which clashes with the matte main aboard, reminiscent of the blue porcelain of the watch case. Often the pointer has been hollowed out to advance enhance the sense of lightness and transparency. popular swiss watch brands
Refined from a single piece of blue, the side of the splint is actually polished with different particles, which often requires highly specialized instruments, excellent precision and competence. The bevel shows some sort of matte finish, which clashes sharply with the polished translucent surface of the sapphire.
On the side of the bottom level cover, the 3D products train bridge plate permits you to unobstructed view of the constructing structure below. This uncommonly large splint has a multi-level design with countersunk holes permitting the wheels to terme conseillé the sapphire accurately.
The case has a height of 48. 40 milimeter and a height of 19. 77 mm. It is created from dark blue ceramic, and that is the first of Greubel Forsey. This material is compacted simply by pressing and forming ahead of firing, where heat cure shrinks it by about 25%. Once the element will be sintered at a very high temp, the ceramic will congeal, making the case very hard and also resistant to scratches and deterioration ., but also more difficult to handle. fake watches for sale
