New in platinum, the Greubel Forsey GMT combines the brand’s signature inclined tourbillon with a dual time zone and world time display that is linked to the three-dimensional globe on the front of the watch.
The 24-second tourbillon is inclined at 25°, meaning it rotates once every 24 seconds on a plane at a slight angle to the dial. The dimensional sphere representing the Earth indicates day or night of any point on the globe. Above this is the second time-zone hand (set in one hour increments by the “GMT” pusher on the side of the case). Hour and minutes with small seconds sub-dial, and a power reserve indicator (far right) round out the black dial. Which, by the way has a very nice looking finely grained texture to it.
On the back is the world time disc showing the time in 24 time zones, and as noted above, it moves in tandem with the globe on the front. While the earlier gold versions of the GMT had grey dials, the GMT Platinum has a black dial. The case remains the same dimensions at 43.5 mm wide and 16.14 mm high. Of course the watch is finished to the highest of standards.
This is multi-dimensional creation is truly something special cased in platinum (43.5mm x 16.14mm). Like all Greubel Forsey pieces, this is a watch for only the most deep-pocketed collectors (price is in the range of $600,000 – $700,000).
