Greubel Forsey GMT Earth

About this reference

The Greubel Forsey GMT Earth in 18k white gold was introduced in 2018 as a limited edition of 33 pieces. Collectors prioritize this reference for its three-dimensional architecture, featuring a rotating titanium globe that provides a synchronized view of world time and a day/night indicator. The manual-wind movement utilizes 453 components and incorporates the brand’s signature 24-second tourbillon inclined at a 25-degree angle. The 45.5mm case includes a lateral sapphire crystal window, allowing a profile view of the equator on the terrestrial globe. On the secondary market, this white gold reference typically commands prices between $350,000 and $500,000 depending on condition and provenance. While the GMT Earth followed the original 2011 GMT, it is distinguished by its complete 360-degree visibility of the globe, a technical evolution that solidified its position as a foundational high-complication piece within the brand’s history.
