Greubel Forsey, specializing in high-end complicated timepieces, stunned the horological world in 2004, having introduced its mind-blowing Double Tourbillon 30° watch.
Since then, the brand has issued three collections, based on this invention. Reflecting the watchmaker’s credo to perfection, the range comprises the Contemporaine line, embracing Vision and Secret models, the Invention assemblage, including the Invention Piece 1 model, as well as the Technique, which boasts the Double Tourbillon 30° Technique model.
This year, Greubel Forsey made a decision to close the Double Tourbillon 30° Contemporaine collection by launching the exclusive Edition Historique watch. The watch is available either in 18k red gold or platinum, each interpretation strictly limited to 11 pieces.
The undeniable highlight of the new Greubel Forsey Double Tourbillon 30° Edition Historique watch is surely its tourbillon system. Created in the early 19th century intentionally for a pocket watch, the rotating mechanism of the tourbillon was targeted at eliminating the effects of gravity.
Robert Greubel and Stephen Forsey pushed back the boundaries of technology by developing a tourbillon caged within a second cage. The creation of this complex construction was aimed at absolute prevention of the rate errors that occurred due to gravity. The sign of 30°, included into the name of the watch, refers to the angle that connects two rotating cages.
The remarkable tourbillon system, however, is not the only aspect that determines the unique complex character of the company’s new brainchild. It is also mirrored in its other components, such as the watch’s 18k gold dial of anthracite color. The real eye-catchers of the display are three sapphire-crystal plates, engraved and enhanced by 3D structured text. The watch bezel features a beveled relief. This charming element magnifies the allure of the Greubel Forsey watch.
The dial also reveals gold hour-markers as well as gold security screws. The display proudly shows off hours, minutes and small seconds indications. They are joined by the Outer Tourbillon 4-minute rotation indicator and the Inner Tourbillon 60-Second rotation indicator. The power reserve information is offered via a polished gold sapphire 4-minute engraved display.
Animating all these functions is a mechanical manually-wound movement - Calibre GF 02E Double Tourbillon 30°. Composed of 303 individual parts, the complicated mechanism is 9.65 mm thick and 36.40 mm in diameter. This movement incorporates the already mentioned two tourbillon cages, which consist of 130 elements. Their total weight constitutes 1.17 g. Incorporating 39 jewels, this caliber runs at the rate of 21,600 vibrations per hour and provides a 72-hour power reserve.
This extraordinary mechanism is housed in an impressive case, sculptured in 18k red gold or platinum. It measures 44.50 mm in diameter, including the plates. On the bezel, however, the diameter is equal to 43.50 mm. The thickness of the case constitutes 16.11 mm.
On the front side, the case is armed with a convex sapphire crystal. The see-through case-back is fitted with the same glass. The back side is engraved with an individual number of the watch. The case also exhibits gold security screws, three-dimensional lugs and a red gold crown, engraved with black lacquered GF logo. The water-resistance of the watch is assured to 30 meters.
The Greubel Forsey watch is secured to the wearer’s wrist on a hand-sewn black alligator leather strap. It is closed with an 18k 5N red gold folding clasp, hand-engraved with the Greubel Forsey logo.
The Greubel Forsey Double Tourbillon 30° Edition Historique watch offers a subtle balance between playful expressiveness and watchmaking sophistication.
