Transparency has always been an integral part of Greubel Forsey creations. This is particularly true of the Double Tourbillon 30° Technique construction. With its three dimensional architecture, the movement mechanism was built in such a way that it encourages unobstructed observation of each separate element and their dynamic interactions.

Designed and developed from the ground up, the central idea behind the Double Tourbillon 30° Technique was to allow panoptic observation of as much of the movement architecture as possible.

The Double Tourbillon 30° Technique Sapphire takes this idea to its logical conclusion, offering full and pure transparency in viewing the mechanism.

Carefully machined from a single large sapphire crystal, the case allows full access to the multi-leveled architecture from all possible angles. The entire movement is flooded with light, rewarding the viewer with an ever-changing spectacle of synchronized rotations, carefully balanced components and sublimely finished micro-mechanics within.

Gazing down through the multiple levels of the timepiece, the viewer is naturally drawn from one element to the next, ever-incited to enjoy yet another vista. Instead of assembling several smaller crystals, Greubel Forsey has taken on the challenge of crafting the entire case, including the rounded, multi angular case horns, from one single sapphire crystal.

The Greubel Forsey Double Tourbillon 30° Technique Sapphire model was unveiled on Wednesday, June 15, 2016 and will be offered to the US market in a limited quantity for a limited time only.
