Only 33 pieces have been produced for the GMT Sport, a watch that favours titanium for both the case and the bracelet, the first metal watch ever made by Greubel Forsey. It is also the first time the company has used the same colour for the movement, a hand-wound mechanical movement: the plate, globe, second time-zone dial and 24-second counting ring at 1 o'clock are all blue. The suspended arch bridge in the centre, as well as the tourbillon bridge, are openworked to facilitate the readability of the multi-layered dial and to make the chosen hue stand out. Price: CHF 520,000 (excluding tax).
