Greubel Forsey is dedicating a brand new calibre to the Terrestrial globe, decisively replacing its predecessors. It is the purest and most contemporary interpretation of the GMT complication ever imagined, deeply rooted in the universe of the brand as well as in Haute Horlogerie. The Earth is showcased majestically, positioned at the very heart of an amphitheatre-like construction. Flush with the sapphire crystal, almost close enough to the surface to touch, it moves in a constant 24-hour rotation, just as the Earth rotates in real life. This amphitheatre is bordered by three rings which indicate two complementary times: hours and minutes local time, as well as universal time.

The beating heart of the timepiece, appreciated by collectors for its remarkable chronometric performance, is a spectacular sight. Once again, Greubel Forsey stuns with its level fine craftmanship. The 30° inclined balance wheel, seemingly suspended in mid-air, is held by a beautiful flat black polished and barrel polished steel balance wheel bridge on polished steel pillars. To its right, the small seconds, displayed with a blue gold hand completes the ensemble. This theatrical composition takes place within the signature convex case designed by Greubel Forsey. Made of titanium and with a diameter of 46.5 mm around the bezel and 43.5mm around the caseband, it hugs the curve of the wrist perfectly. It also represents the major technical feat of achieving a movement that follows an imperceptible slope of just a few degrees. The sapphire crystal and satin-finished bezel follow the same curved geometry, which extends onto either a titanium bracelet or a textured rubber strap.
