The GMT Balancier Convexe is a wristwatch by Greubel Forsey.

This model was presented in August 2022. It features a 30° inclined balance wheel system, GMT function, 2nd time zone, rotating globe with universal time and day-and-night, universal time on 24 time zones, summer and winter time and cities observing summer time.

It is the first GMT caliber with the characteristic inclined balance. The dominant positioning of the globe on the dial is striking. The convex case nestles comfortably on the wearer's wrist.

Like the Earth itself, the globe display completes one full rotation in 24 hours. This display is framed by three rings which indicate two complementary times: hours and minutes local time, as well as universal time.

The 24 time zones displaying universal time are set against a black background if the time indicated is at night, and on a white background during the day time.

Local time is indicated on the two outer rings: one for the hours on a grey satin-finished ring, and minutes on a thin black outer ring. Each time indication has its own hand with a red triangular tip filled with luminescent material. These hands move on two further rings to display GMT. Finally, an off-centre display at 10 o’clock indicates a second time zone with a blue gold hand.

On the case back a disc shows the 24 time zones indicating the UTC time of the 24 reference cities.
