For Greubel Forsey, transparency has always been a key to their creations. The watch manufacture therefore takes a new play at the world by literally creating a unique timepiece out of a transparent material--the sapphire glass. In this case, the Double Tourbillon 30° Technique Sapphire was born; something which is totally unexpected, yet absolutely delightful that every watch connoisseur must see in order to believe.
Crafted with a three-dimensional construction, this watch stars a movement mechanism that was assembled in a way that it encourages unhindered view of every element and its dynamic interaction. It was designed and developed from scratch, where the central idea was to produce a panoptic vision as much as the architecture allows. From here, Greubel Forsey cheekily made the impossible possible, by playing with a fragile yet enduring material, and successfully producing a watch that is worth millions.
The Double Tourbillon 30° Technique was meticulously drawn from this concept, developed with the best of watchmaking innovations. The entire case was carefully machined from a solid, single piece of sapphire crystal--something which only technological artisans can so. The case showcases the multi-leveled architecture from all angles, where the crystal material allows the passing of light, giving the user a haunting spectacle of synchronized movement, rotations and clicks. Here, an entire assembly of beautifully finished micro-rotors take the stage and become the main hero. Layer upon layer shall one look, where the beautiful movement is finally captured by the eye and enjoyed with true relish.
Instead of putting together several smaller sapphire crystal glasses, the manufacture took on the challenge of creating the entire case and finished it to perfection. The dial is rounded and is composed of multi-angular case horns, and all of these are derived from a solid piece. With pride, Greubel Forsey unveils this beautiful make, offering a new discovery for timepiece enthusiasts.
Double Tourbillon 30° Technique Sapphire is a 38.4mm case composed of a 396-part movement with a hand-wound caliber. Two tourbillon escapements are allowed to move on their own; one is places inside the other. The use of double tourbillons only guarantee precision; the outer one takes rounds at every four minutes, while the other rotates every one minute. In this feat, Greubel Forsey was able to obtain a 915 score out of 1,000 points as given by the International Chronometry Competition.
The watch is packed with 120 hour of power reserve and can be worn with a black strap. This US-exclusive timepiece series has only 8 items in retail.
