Greubel Forsey GMT marks a first for Greubel and the history of GMT watches. True to Robert Greubel and Stephen Forsey's philosophy and their traditional approach, they were not content with the traditional display of a time zone by the jumping hour in an aperture or by a hand. The GMT displays a three dimensional globe that makes a full rotation in 24 hours, counter-clockwise. The calibre of this timepiece features the 25° inclined Tourbillon 24 Secondes cage, one of Greubel Forsey’s major patented inventions, and has a 72 hour power reserve.
