Double Tourbillon 30° Technique is the iconic watch of independent brand Greubel Forsey and has long been a favorite of collectors. The watch is usually only available in noble materials, and the new blue ceramic case is now designed to join the 21st century. In addition, the watch’s movement has been completely rebuilt and reconfigured-using a lot of sapphire elements to achieve amazing transparency.
This marked the first time that Greubel Forsey made a watch case with high-tech ceramics. The stunning blue hue is reminiscent of the colors on the American flag. It is made of only 11 pieces and the number is very limited.
The original Double Tourbillon 30° Technique (Double Tourbillon 30° Technique) was the creation of Robert Greubel and Stephen Forsey in 1999. It was not realized until 2004, which shows the complexity and superb technology of this timepiece. The tourbillon escapement can compensate for timing errors in certain positions due to the influence of gravity on the wrist.
The patented 30° double tourbillon has two tourbillon cages: a four-minute tourbillon cage, and a second small cage with a balance wheel and spring assembly, located in a larger cage. The small cage is tilted 30 degrees and rotated every 60 seconds. The inclination of the tourbillon escapement and the different speeds work together to improve accuracy.
Inside the movement are multiple three-dimensional sapphire bridges-each bridge is processed from a piece of sapphire. The process of creating the bridge requires hundreds of hours of processing time. The sapphire bridge makes the movement and escapement more clear of vision. replica Greubel Forsey Watches
In addition, since sapphire is fragile and may break, all sapphire bridges are specially installed to absorb shocks. The sapphire crystal back cover can watch the complex movement. Each of the 421 parts of the manual-winding mechanical movement is meticulously finished by hand in a typical Greubel Forsey style.
On the dial side, the blue element is actually gold and finished in blue to complement the blue ceramic case. The diameter of the ceramic case is 48.40mm, which is also a remarkable feat. The material is pressed into shape before firing. However, the sintered shell becomes very scratch-resistant and corrosion-resistant.
The watch replica provides hour and minute display, small seconds indicator, 120-hour power reserve on a sector indicator, and two tourbillon escapements. The timepiece is equipped with a blue rubber strap and is water-resistant to 30 meters.
