    Such a vision is obvious in the present timepiece: the asymmetric case and multi-tiered dial with three-dimensional globe are as visually striking as they are technically refined. But all the complications of the piece are actually evolutions of well-established complications/regulating organs (world time, dual time, tourbillon) reinterpreted in post-modern key and executed with the highest standards of traditional watchmaking.

    The local time is obviously read in the mean subdial at 12 o’clock, with a small peripheral counter for the constant seconds. Proceeding clockwise, the eye falls on the power reserve indication and then on the tourbillon regulator. The inclined tourbillon is one of the defining feature of Greubel Forsey. Not only it presents a 25 degrees inclination, but it furthermore rotates at an astounding rate of one revolution every 24 seconds (most tourbillon rotate once per minute) allowing for a much better gravitational compensation. The technical challenges the manufacture had to overcome in order to achieve such a feat of engineering are simply daunting.

    At 7 o’ clock one can find a truly groundbreaking world time display: Greubel Forsey tackled this complication in a truly literal way, and devised a revolving three-dimensional realistic representation of the earth with a diameter of circa 13 mm surrounded by a 24 hours ring indicating the time in correspondence of the appropriate location. This complication perfectly mirrors - in scale about 1 to 980million - the actual motion of the planet. Finally, at 11 o’clock one find a more classic dual time indication, which can be easily adjusted by the correspondent pusher.

    The surprises of this timepiece do however not end here: on the movement side, one can notice an additional world time indication featuring 24 world cities on a rotating disc. While apparently slightly more conventional than the globe, the ingenuity of Greubel Forsey devised a way to appropriately correct the reading according to solar time or daylight saving (summer) time: two 24 hours rings are placed at the edges of the city disc. The outer ring shall be used in winter. The cities adopting daylight saving time are placed on white sectors, those which do not on black sectors. During summertime, one shall use the inner disc to read the time of “white sector” cities. This simple but clever escamotage effectively solves one of the greatest issues of world time timepieces: the management of summertime.

    The piece is offered by its original owner in absolutely mint, never used condition - the strap unbent - and complete of all its original accessories, from the guarantee booklet to the superb presentation case.
