Greubel Forsey-Double tourbillon 30° hard technology
The actual double tourbillon 30° may be the first basic invention associated with Robert Greubel and Sophie Forsey in pursuit of extreme accuracy. Greubel Forsey Double Tourbillon 30° Invention Piece 1 Vision
Showed at the Basel Watch Reasonable in 2009. Seven years later on, their double tourbillon 30° technology won the first reward on Concours. The Worldwide de Chronométrie set an archive of 915 points (out of 1000 points) having an average timekeeping rate regarding 0. 3 to zero. 8 seconds per day through the entire competition.
The particular timepiece is housed within a blue ceramic case and it is the latest interpretation of this unique creation.
Typically the Greubel Forsey double tourbillon 30° technology provides outstanding precision in ceramics because of a unique solution: in which the crate assembly with a smaller stability and spring is bent at an angle of 30° whenever rotating within four moments The inner angle of the competition is relative to the first dog crate and completes a group within 60 seconds. The 30° inclination angle combined with the various rotation speeds of the 2 tourbillons improves timekeeping through averaging the position error brought on by gravity in all usual view positions, especially in stable jobs.

4 coaxial barrels are linked to a spherical power reserve differential to provide a 120-hour chronograph reserve of power. The movement beats in a frequency of 3 Hz (21, 600 vibrations per hour).
Since the link, the hour and moment rings, and the 4-minute tourbillon rotation indicator at six o'clock all use sky-blue crystal, the movement framework can be appreciated from both equally sides and as a whole.
The gold small secs and power reserve indicator possess a blue finish, which clashes with the matte main panel, reminiscent of the blue fine ceramic of the watch case. Often the pointer has been hollowed out to increase enhance the sense of lightness and transparency. popular swiss watch brands
Prepared from a single piece of blue, the side of the splint is actually polished with different particles, that requires highly specialized resources, excellent precision and experience. The bevel shows the matte finish, which clashes sharply with the polished clear surface of the sapphire.
On the side of the bottom part cover, the 3D equipment train bridge plate enables you to unobstructed view of the creating structure below. This abnormally large splint has a multi-level design with countersunk holes to permit the wheels to terme conseillé the sapphire accurately.
The case has a size of 48. 40 milimetre and a height of seventeen. 77 mm. It is made from dark blue ceramic, that is the first of Greubel Forsey. This material is compacted simply by pressing and forming prior to firing, where heat therapy shrinks it by around 25%. Once the element will be sintered at a very high temperatures, the ceramic will harden, making the case very hard and incredibly resistant to scratches and deterioration, but also more difficult to handle. fake watches for sale
