GMT Earth

38 pieces (2018-2022) | White gold | Platinum | Titanium

With this creation, Greubel Forsey are once again pushing the envelope and venturing into uncharted territories. The GMT Earth provides an amazing 360˚ view of our planet Earth all the way from the North to the South Pole. This technical feat was achieved by an original movement architecture in relation to the case shape and dimensions. Revealing the entire terrestrial globe required complex application of sapphire crystal, a skill which Greubel Forsey has acquired over many years of research and utilization.

The globe is not the only three-dimensional element in this timepiece – it’s a characteristic that features at every level. The three-dimensionality first appears at the highest point of the dial, with the hour, minute and small seconds indications. Then the gaze glides gently across the GMT indication with its triangular red hand, followed by the power reserve indication displayed by a long, slender hand. Finally, our eyes come to rest on the lowest part of the dial, which shows the globe alongside the Tourbillon 24 Secondes, Greubel Forsey’s 3rd pivotal Invention.

The GMT Earth enables a clear view of three time zones simultaneously to within a quarter of an hour. Furthermore, on the movement side of the timepiece, 24 time zones are displayed with the summer and winter times to complement the universal time indicated by the terrestrial globe.

The proportions of the case were constructed to accommodate the high-domed sapphire crystal bezel and the special artistry on the caseband. The characteristic lateral plates bearing engraved inscriptions that encapsulate the key values of Greubel Forsey decorate the case body.

Tourbillon 24 Secondes

The Tourbillon 24 Secondes uses a fast rotation speed and inclined angle to solve the problem of critical positions of the oscillator in relation to gravity. The 25˚ angle and the rapid rotation of the tourbillon cage significantly improve the chronometric performance of a system containing only one tourbillon, especially in stable positions. Consequently, we had to develop an inclined gearing profile and an ultra-light tourbillon cage to resolve the considerable mechanical constraints imposed by this system.
