In 2011, Greubel Forsey revolutionized the field of GMT —dual time zone— watches with their innovative timepiece and its original technique, aesthetics and practicality. Its exceptional precision movement, featuring the 24-second tourbillon with 25° inclination, now comes set against a platinum backdrop. This new Greubel Forsey unveiled this week at the SIHH 2014, is exactly like the two other GMTs available in 18K rose gold or 18K white gold, but this time in 950 Platinum —which shines with a whiter hue when compared to its white gold counterpart. The best way to differentiate the white gold model from this one —aside from the obvious whiter hue of the metal— is by the black dial and black alligator strap on the platinum vs. the grey dial and blue alligator strap on the white gold model.

This watch previously reviewed here features a second time zone indication complemented by a three-dimensional terrestrial globe —referred to as a Planisphere by Greubel Forsey— providing an intuitive picture of time all over the world in a distinctive asymmetrical case measuring  43.5 mm in diameter and 16.14 mm in thickness.

A dual-function pusher located on the left caseband —at what would be the 10 o'clock position— with GMT engraved on it, allows for quick setting of the second time zone that is indicated on a small register at 10 o'clock as well as adjustment of the rotating globe that is synchronized with a cities disc on the back of the watch. The dial features a 72-hour power reserve indicator at 2 o'clock right underneath the seconds register. The local time is shown on the off-centered gold frosted anthracite treated dial at 12 o'clock. The sapphire crystal opening on the caseband at 7 o'clock allows for full view of the delicately finished terrestrial globe and to allow for light to go in which indicates those areas of the world where it is daytime. The terrestrial globe makes one complete rotation every 24 hours anticlockwise —the Earth’s natural rotational direction viewed from North pole— and the position of the continents can be easily cross-referenced with the time on the equatorial chapter ring which is marked with 24 time zones and day/night indication. The night-time hemisphere —18:00 to 6:00— is indicated by a blackened half of the ring around the globe, while the daytime hemisphere —6:00 to 18:00— is indicated by a whitened portion. Midnight is indicated in red while noon is in yellow.
