Adhering to the spirit of independence and exclusivity, Greubel Forsey (fake Greubel Forsey) decided in 2010 to end the Double Tourbillon 30°Contemporaine by creating two unique series “Editor Historique”.
Since the launch of the Double Tourbillon 30° double tourbillon in 2004, Greubel Forsey has released 3 product lines according to the present invention, namely: Contemporary (including Vision and Secret models), Invention (including invention 1 model) and Technique (Double Tourbillon) Flywheel 30° technical model). Double Tourbillon 30°Edition Historique adhering to the spirit of independence and exclusivity, Greubel Forsey decided to terminate the double tourbillon 30°Contemporaine in 2010 and launched two unique series, namely the “Edition Historique” series: 5N rose gold and Double Tourbillon 30° The closure of the Contemporaine watch is an important symbol of the brand: the series has always been deep in history, because it was the timepiece that launched Greubel Forsey’s adventure and laid the foundation for the legality of subsequent inventions. After six years of success, the decision to stop Double Tourbillon 30°Contemporaine Double Tourbillon Contemporaine will also enable Greubel Forsey to inject new energy into creating systems, inventing and exploring new ways.
The complexity of transcending the invention of timepieces is not limited to the tourbillon system, but also obvious in other aspects including the new dial. This exclusive gold dial integrates three sapphire crystal plates. These complex inserts are sculpted and enhanced with 3D structured text. The bezel with beveled relief gives the final version an original appearance, a new interpretation of the style of earlier models, while retaining the inherent design features of Greubel Forsey timepieces. Like other Greubel Forsey timepieces, the Double Tourbillon 30° expresses the ideas of its creator. Visually, you will also find 3D structured text on the dial, and a curved plate engraved with hand decorations is pasted on the side of the case to commend the inventor’s watchmaker’s ideas and skills.
The tourbillon was invented for pocket watches in the early 19th century, and it has hardly changed since then. Its purpose is to eliminate the balance of the balance spring caused by gravity. However, since the start of the adventure together, the inventor’s master watchmakers Robert Greubel and Stephen Forsey have been seeking achievements beyond the science of watchmaking, and further complexity and research to be effective Improve the operability of the watch.
They developed a tourbillon cage, which is placed in the second cage. Therefore, considering all the regular positions of the watch, this new feature will permanently eliminate the rate error caused by gravity. It is called the Double Tourbillon 30° (Double Tourbillon) due to the angle at which the two rotating cages are connected. This patented system provides a decisive technological advancement and marks a milestone in the history of watchmaking.
