Greubel Forsey Double Tourbillon 30 ° Technique Ceramic

Greubel Forsey Double Tourbillon 30 red gold Silver Replica Watch

In search of extremely high precision, Robert Greubel and Stephen Forsey began to create a work in 1999 that reinterpreted the tourbillon and improved the timing function. The double tourbillon 30 ° is Grauber Fossi’s first basic invention and was exhibited at the Basel fake watches for sale Fair in 2004. This proves the success of the independent studio. Seven years later, the double tourbillon 30 ° technology won first place in Concours. International Times. Throughout the competition, the timer scored a record 915 points (out of 1,000 points), with an average timing speed of 0.3 to 0.8 seconds per day.

Now, Greubel Forsey has launched the blue ceramic double tourbillon 30 ° technology, which is an extremely accurate, delicate and strong timepiece.

Unparalleled precision timepiece center
The 30 ° double tourbillon contributes to its extraordinary accuracy. Inside the cage that rotates for four minutes, a smaller cage equipped with a balance wheel and spring assembly is tilted at an angle of 30 ° relative to the first cage, and completes the rotation within 60 seconds. Combining the 30 ° inclination with the different speeds of the two tourbillons can average out the position errors due to gravity in all conventional watch positions (especially stable positions), thereby improving timing performance.

In the Double Tourbillon 30 ° double tourbillon technology, four coaxial barrels are connected to a spherical power reserve differential, which provides a 120-hour chronograph power reserve.

Ceramic case: robustness and luminosity
This is the first time Greubel Forsey copy has demonstrated the movement inside a ceramic case. The manufacture of this case requires extremely high precision. The material is compacted by pressing and then shaped before firing. During the heat treatment, the material shrinks it by about 25%. Once the element is sintered at a very high temperature, the ceramic will solidify, making the watch case very hard and therefore more difficult to use. The material becomes very resistant to scratches and corrosion, which means that surface treatment requires excellent expertise. From polishing to linear or circular satin polishing, the surface treatment can perfect the outline of the timepiece, perfected with the true Greubel Forsey spirit. The dark blue ceramic brings a subtle flash to the Double Tourbillon 30 ° technology, while its physical properties make it extremely resistant.

Green Machinery: Seiko and Swiss Amazing Special Edition GMT Watches

Grand Seiko x The Watches of Switzerland Group Toge Special Edition Men copy watch SBGM241 for sale

For brands and retailers, the new SBGM241 is the best of both worlds, and it is the perfect combination.

Hot media: Grand Seiko replica and Watches of Switzerland teamed up to create the first collaborative work. The new “Toge Special Edition” combines the Japanese and British heritage of the two brands to form a real East-West timepiece.

Regarding the special edition of Toge (SBGM241), the first thing you might notice is the striking green dial, which is the meeting point between the two cultures. This is not only green, but also British racing green.

Green and shadow of high mountain pass
Iconic shadows are legends of several generations of British racing teams, including Bentley at the Le Mans in the 1920s, Bugatti at William Gover Williams at the 1929 Monaco Grand Prix, and Aston Martin and Lotus , Vanwall, Cooper and BRM throughout the 1950s and 1960s.

Layered shadows are combined. In Japanese, the word Tōgè means “mountain pass”. This is a suitable name for the new model. Especially when considered together, the green layered shadow and the texture of Grand Seiko’s iconic Iwate Mountain dial subtly evoke the image of the drive across the ridge of Iwate Mountain in northern Japan.

GMT accent
Another prominent feature here is the GMT golden pointer. This adds bright colors to Grand Seiko’s conservative design, and according to the brand’s news pictures, the color of the dial is beautifully supplemented, adding a nod to the racing tradition behind the green dial. Not to mention, the Greenwich Mean Time function means that the best watch is ideal for traveling between time zones, such as the United Kingdom and Japan.

Beauty from the inside out
The 39.5mm stainless steel case is the original work of Nobuhiro Kosugi, the chief designer of Grand Seiko. He is the same person who created the modern 44GS case design. The thickness of the case is 13.7mm, which is crescent-shaped. Due to Seiko’s iconic Zaratsu polishing technology, the watch will also shine like the moon.

Under the hood is the 9S66 movement with a 72-hour power reserve and an accuracy of -3 / + 5 seconds per day. The 35 jewel movement is an upgrade of the Seiko 9S56 movement with a 48-hour power reserve. For people who travel frequently, a cool thing is that you can change the hour hand without affecting the minute and second hands. Like many other Grand Seikos watches, this beautifully decorated movement can be seen through the sapphire caseback.
