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.
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 brand is proud to have been able to find the perfect way of adapting this notoriously challenging material to the unique shape of a Greubel Forsey case.
The Double Tourbillon 30° Technique Sapphire is offered to the US market in a limited quantity for a limited time.
