By combining the quadruple tourbillon wheel with the GMT mechanism, Greubel Forsey(greubel forsey double tourbillon 30° technique ) not only accomplished a major technical feat, but also created a new hand-wound caliber that includes 705 components, including three rapidly rotating barrels. The inventor watchmaker also addressed this challenge from an architectural perspective, creating a 3d way to express the clock on many levels. The main hour/minute dial between 1 and 2 points forms the highest point on the dial, highlighted by a slight asymmetry in the case, complemented by a 72-hour timing power reserve display. The next layer is displayed at 4 o 'clock, coaxial small seconds and second time zone, which can be adjusted increments in an hour by pushing. Observers can enjoy a spectacular view of the earth's orbit between 8 and 9 o 'clock, surrounded by a fixed 24-hour ring that shows the local time for all longitude -- and allows for day and night indicators (in the light/dark areas).
The transverse window in the asymmetric section provides an unprecedented view of the equator and the southern hemisphere. The four tourbillon wheels are drawn into two pairs on either side of the blue planet, each with an open and transparent structure,swiss replica watches , fixed by a black polished flat bridge, decorated with golden tenons and grooves and hand-polished bevels and basins.
The world time is visible from the back of the case, with a fixed 24-hour scale, marked by areas of day and night, and a disk with the initials of 24 cities, representing different time zones. The disk also distinguishes time zones that implement summer time (daylight saving time), which are shown in light colors; Those that don't. The back of the box also offers an opportunity to enjoy the quadruple tourbillon as well as the frosted bridge with jewelry set in the gold chawton. Two complex asymmetrical convex sapphire crystals protect the dial and the back of the case and also require maximum expertise.
This masterpiece of contemporary aesthetics has 66 unique editions. The first edition of 11 of them, numbered 01/11 to 11/11, is made of white gold and is placed on a plate in the center of the dial.
