Greubel Forsey has decided to make another edition of its GMT timepiece with an inclined tourbillion. However, this tilted tourbillion with the period of rotation of 24 seconds is not even the most striking trait of the piece, since it is eclipsed with a lovely three-dimensional representation of the globe. Not just that it looks realistic, it also moves exactly like our planet does. The third edition of the watch, which comes after the initial golden and the subsequent platinum cased versions, is made with a titanium housing which is blackened with the addition of amorphous diamond-like carbon finishing. Greubel Forsey GMT Black will be shown to the public for the first time at the approaching SIHH 2015 show. It is made in an exclusive 22-piece limited edition and it will be sold at the very steep price of $565,000.
GMT timekeeper by Greubel Forsey which we wrote about several times (first time when it came out at the SIHH 2012) is among the very cream of high-end watches thanks to its immense complexity and demanding finishes. Probably the first thing that one notices about the watch is its realistic globe depiction which dominates its face. The lovely detailed three-dimensional representation of the Earth is visible from the front, as well as from the transparent section on the side of the irregularly-shaped case, While the front side depicts the Northern hemisphere, the Southern one can be seen through the case-band. This globe is so impressive since it enables the wearer to see the time in each of 24 time-zones simultaneously. It revolves in the anti-clockwise direction and thus realistically replicates the rotation of our planet. Understandably, it was extremely hard to create such complication. As the manufacturer revealed, it took a year and a half just to develop this specific feature.
Beside the globe that stands behind the name of the watch, one can notice another extremely impressive complication – an inclined tourbillion cage (at the angle of 25 degrees) which completes a full revolution every 24 seconds. The ultra-light tourbillion consists of 78 components. Otherwise, the face also includes an offset dial for hours and minutes, a small seconds counter, a 12-hour second time zone counter, as well as an indication for its three day power reserve that is enabled with twin barrels. More indications can be seen on the rear side of the case which include an hour disc with 24 cities and an indication that shows in which one of them noon currently is. All of these features are enabled with its superbly hand-finished proprietary GF05 movement which is comprised of 436 components. Among the demanding decorations of the hand-wound caliber there are beveling, frosting, straight graining and polishing.
After the two initial golden versions of the model (in white and red gold) and the subsequent platinum 950 variant, the manufacturer opted for yet another iteration. The latest version which will have its debut at the end of the month in Geneva comes with a titanium case which is treated with ADLC (amorphous diamond-like carbon) coating which stands behind its lovely deep and translucent black color, but also makes it much more tough and resilient. The case is made with the diameter of 43.5 mm and the thickness of 16.4 mm. It is a bit thicker case, but that is quite understandable considering the three-dimensional representation of our planet, as well as the overall intricacy of the movement.
The technical marvel from the brand led by Robert Greubel and Stephen Forsey is coupled with a black strap. The attachment is made of layered rubber and it fastens with a folding clasp. As it could be expected, the latest iteration of the ultra-complex watch will have the price to match its quality. Each of just 22 copies of the new version of the piece will have the price of well over half a million dollars.
