First Look – The New and More Compact Greubel Forsey GMT Balancier Convexe, in Blue
Greubel Forsey introduced its impressive three-dimensional GMT complication in 2011. Equipped with a rotating globe and an inclined 24-second tourbillon regulator, the complications were housed in imposing cases with a protrusion to accommodate the globe and a windowpane on the flank to admire its rotations.
