After creating complicated tourbillon mechanisms for over a decade, Robert Greubel and Stephen Forsey have finally built their own timepiece, catering to new age world citizen. With the GMT co-ordinate World Time complication on the main dial itself, this timepiece is meant for the travelling executives, or the world tourist whose destinations may change at any time. The sleek design and precise craftsmanship on the overall, is something which is also complementary.
The casing of the watch has a 43 mm diameter, and is made of 18 carat white gold. On the 8 ‘o’ clock position, is the blue titanium earth shaped globe which has been the main highlight the timepiece. Affixed at the South Pole, this globe displays the time of various zones across the world, through the surrounding dial, which has hours indicated in a 24-hour format. The complete rotation takes place in an anti-clockwise direction, and takes the normal 24-hours. This circle is colored half in white (18:00 to 6:00 hours) indicating the day, where the other half in black indicating the night time. The actual timings are shown on the smaller dial towards the top right corner, displaying hours and minutes in Arabic numerals. The 4 ‘o’clock position of this mini-dial, is the seconds dial. There is also the 72-hour power reserve indicator at the bottom right hand corner.
On the technical front, there are 436 components of various sizes in this timepiece, out of which the tourbillon has 87 of these parts. This also includes 50 precious jewels used as a part of the tourbillon. The vibration rate of the mechanism is 21,600 vibrations per hour, which also operate the second World Time dial on the back of the main dial. The watch strapping is done is optional white or blue alligator handstiched leather. The surprising factor is that the timepiece has no fixed limited editions, unlike most precious ones which have a fixed production run. However, each of them will have the individual numbering indicated on the black dial.
