Now, Greubel Forsey introduces the ceramic double tourbillon 30 ° technology, which is an extremely precise, delicate and sturdy timepiece.
The dual tourbillon 30 ° at the center of the timepiece contributes to its extraordinary accuracy. Inside the cage that rotates for four minutes, a smaller cage with a balance wheel and spring assembly is tilted at an angle of 30 ° relative to the first cage and completes rotation in 60 seconds. The combination of the 30 ° inclination and the different speeds of the two tourbillons can average out all conventional watch positions (especially stable positions) due to gravity-induced position errors, thereby improving timing performance.https://www.chronosale.co
The double tourbillon 30 ° is the first fundamental invention of Glauber Fossey and was exhibited at the Baselworld in 2004. This proves the success of the independent studio. Seven years later, the dual tourbillon 30 ° technology won the first place on Concours. International timing. Throughout the game, the timer’s total score reached 915 points (maximum 1000 points), with an average daily speed of 0.3 to 0.8 seconds.
In the Double Tourbillon 30 ° dual tourbillon technology, four coaxial barrels are connected to a spherical power reserve differential, which provides a 120-hour timed power reserve.
Inspired by the phenomena of transparency and light, Robert Greubel and Stephen Forsey are pushing the boundaries of horological architecture to draw onlookers deeply to the symbolic Glauber Fo West (Greubel Forsey) timepiece. This limited edition of 11 timepieces is made of ceramic for the first time, is a highly rigid material, and is already on the US market.
The shadow of the impressive delicate blue ceramic case contrasts with the flood of light in the sapphire crystal movement. Clocks have been redesigned to integrate these elements and require very special expertise and knowledge. It now reveals the fascinating sight of two fully suspended double tourbillon 30 ° movements.https://www.chrono36.com
Transparency has always been an integral part of Greubel Forsey’s work, and this is especially evident in the construction of different versions of the Double Tourbillon 30 ° double tourbillon technology-all presenting a panoramic view of the movement architecture. This dual-ceramic tourbillon 30 ° technology breaks through the boundaries of transparency by reconsidering the structure of the entire timepiece to meet the special constraints of sapphire crystal.
The eye can tell every detail. The small gold seconds hand and power reserve indicator are finished in blue, in sharp contrast to the frosted motherboard, reminiscent of sparkling blue ceramics.
The hour and minute hands and the 4-minute tourbillon rotation indicator at 6 o’clock are immersive structures made of sapphire, allowing light to enter all levels of the mechanism. The hands are hollowed out to further enhance light and transparency. As if suspended in a mysterious dance in the air, Double Tourbillon 30 ° immediately caught the attention of the audience.
After rebuilding the movement, Robert Greubel and Stephen Forsey faced the challenge of accommodating the sapphire crystal element, especially machining and finishing in three dimensions to reach the Grobel · The unique geometric shape and strict standard sapphire elements of Fuchsi watches.Hublot MP-02 Key of Time 902.ND.1190.RX replica watch
The watchmakers of the two creators brought the movement to the extreme of the building, creating a three-dimensional sapphire bridge, which proved to be particularly difficult to achieve. Processed from a single piece of sapphire, the sides are polished with different grains, requiring highly specialized tools, excellent precision and expertise. The beveled angle reveals a matte finish that contrasts sharply with the sapphire-polished transparent surface.
Because of this transparency, the entire wheel and pinion that make up the timepiece are exposed to reveal an unprecedented visual experience of the movement structure.
On the dial side, the tourbillon bridge, barrel bridge, differential bridge and power reserve bridge have been removed and remade in sapphire to showcase the internal mechanism of the timepiece. To incorporate these new elements, sports must be reconsidered. In this creative spirit, even the limitation imposed by screws is considered: the bridge is specially installed to absorb the impact that sapphire may suffer. As a result, plates, bridges and mechanical structures are completely new.
On the side of the bottom cover, the three-dimensional gear chain bridge can clearly see the magnificent building below. This unusually large bridge has a multi-layer design with counter holes that allow the wheels to precisely overlap the sapphire. The whole mechanism emits light, rewarding onlookers with fascinating sights. The lower tourbillon bridge (also made of sapphire) accurately replicates the steel bridge originally made with Double Tourbillon 30 ° technology, marking a major achievement in sapphire craftsmanship.
This is Greubel Forsey’s first demonstration of the movement inside a ceramic case, which requires extremely high precision in its manufacture. The material is compacted by pressing and then shaped before firing. During heat treatment, the material will shrink it by about 25%.Audemars Piguet Royal Oak Replica Watches
In the end, the case had a diameter of 48.40 mm and a height of 17.77 mm. Once the component is sintered at a very high temperature, the ceramic solidifies, making the case very hard and therefore more difficult to use. The material becomes very resistant to scratches and corrosion, which means that surface preparation requires excellent expertise.
From polishing to linear or round satin finishing, these finishings can perfect the outline of the timepiece and complete it in the true Greubel Forsey spirit. Dark blue ceramic brings subtle sparkle to Double Tourbillon 30 ° technology, and its physical properties make it extremely resistant. The blue ceramic case and sapphire movement are full of countless colors, surface treatments and textures.
This iconic timepiece with blue ceramic and its new architecture will be released as a unique version of 11 timepieces, only available in the US market.
It comes with a blue rubber strap, a titanium folding clasp, and a hand-engraved Glauber Fauci logo. The crown-also ceramic-bears the Greubel Forsey logo engraved in tones.Versace replica watches
