The GMT watch by Greubel Forsey has changed with the help of a revisited case and movement. The judicious use of sapphire results in an original vision on a magnified representation of the earth.

In 2011, Greubel Forsey unveiled a timepiece that was both highly technical and poetic: the GMT. As its name suggests, the movement can display a second time zone. Like the work of the talented watchmaking duo, the dial provided an unconventional display and the use of depth with the highlight of a three-dimensional terrestrial globe. This representation of our planet displayed the time in 24 time zones turning anti-clockwise. To see the southern hemisphere, a side opening in the case provided an equatorial view of the revolving Earth. But clearly, this was not quite enough… Robert Greubel and Stephen Forsey have gone back to work to provide an all-round vision of the blue planet, from the North to the South Pole. The result is the GMT Earth made in 33 pieces.

The 45.5mm caseback is made of grey gold and has been redesigned to include a sapphire element made up of a dome that reveals the Earth as a whole. The dial has also been modified to add more light. The hour rim, the GMT indicator, the running seconds and the power reserve indicator are included in a multi-level sapphire. The indices are engraved and filled with lacquer.

The calibre is still controlled by a 24-second tourbillon tilted at 25°, a technical signature of the brand. The two fast-rotating mainspring barrels in the hand-wound movement provide enough energy to drive the time information and a comfortable power reserve of 72 hours to the GMT Earth.
