The GMT of Greubel Forsey it debuted in 2013 and today, it is presented in this new version that combines two double tourbillons with the GMT complication, making it even more spectacular.

To do so, Greubel Forsey not only accomplished an important technical feat that resulted in the creation of a new hand-wound caliber comprising 705 parts, including three fast-rotating barrels, but he also addressed this challenge from a standpoint architectural to create a timepiece in which the three-dimensional approach was able to express itself on several levels,

The hour and minute dial between 1 and 2 is the highest point of the dial, where it is emphasized by the subtle asymmetry of the case and complemented by a 72-hour power reserve chronometer display. The next level is at 4 o'clock, with the small coaxial seconds and the second time zone display that is adjustable in one-hour increments via a button. Located between 8 and 9, observers can admire the spectacular view of the Earth in motion, surrounded by a fixed 24-hour ring around the Equator, capable of displaying the local time for all longitudes, also taking into account the 'day and night indicator.

Universal time is visible through the back of the case, with a fixed 24-hour scale, with day and night zones, and a disc with three-letter abbreviations of 24 cities representing the various time zones. This disc also distinguishes time zones that implement daylight saving time with a light color and those that do not, shown on a dark background instead. The back of the case also offers the opportunity to admire the Quadruple Tourbillon. Available in only 66 pieces, 11 of which in white gold, at a price of around 820.000 euros.
