Description

Bold design, no compromise on the materials, exquisite execution, and hand-finishing of all the single pieces, mechanical inventiveness and the continuing search for extreme precision. True to their philosophy and continuous quest for perfection and innovation, Greubel Forsey have gone way beyond the conventional means of displaying a second time zone. The GMT features a wonderful, three-dimensional temporal representation: A rotating terrestrial globe offering a truly original view of time all over the world. This technical yet poetic marvel provides us with a completely new way of perceiving the different time zones.

This movement, entirely developed and produced by Greubel Forsey, features several delicacies. As said, there are multiple indications but also some technical beauties. All of the indications can be controlled by the crown, except the GMT hand that can be adjusted in one-hour increments by the pusher at 10. It also comes with a 24-second tourbillon inclined at 25 degrees.

Here, with the Greubel Forsey GMT, we have a tourbillon that rotates in 24 seconds and that is not on a flat axis. As the goal of a tourbillon is to counteract the gravity with a constant movement, you’ll easily understand that the faster the rotation, the better the result is. Then, applying a 25 degrees angle on the axis also tend to have more positions for the regulating organ and to have a balance wheel that is never parallel to the ground (where the gravity has the stronger effect on the regulating organ). Combining these two characteristics create a super-strong anti-gravity device that will (theoretically) increase the precision of the watch, due to a more stable rating (technologies that permits Greubel Forsey to win the International Chronometry Competition in 2011 with an exceptionally high score and a incredible precision, with a Greubel Forsey Double Tourbillon 30 degrees).
