This is the latest example of the Greubel Forsey GMT complication and the first GMT watch from the small-batch, extremely tactile tourbillon and chronometer specialist. It debuted in 2013 and combines a 24-second tilting tourbillon tilted at 25° with a very beautiful spherical model of the globe that rotates once every 24 hours, driven by the same gears that drive the GMT complication.
