Greubel Forsey GMT Balancier Convexe
The Greubel Forsey GMT Balancier Convexe presents a more compact and complete interpretation of the Maison’s distinctive GMT complication. Limited to just 22 timepieces, its 42.9 mm titanium case houses an intricate three-dimensional display built around a miniature terrestrial globe that rotates in real time over 24 hours.
Surrounding the globe are indications for local time, a second time zone, universal time and day/night, alongside worldtime across 24 time zones and summer/winter time. The signature 30° inclined Greubel Forsey balance wheel is suspended beneath a black-polished steel bridge, while a newly integrated 72-hour power reserve completes the dial architecture. Available on either a titanium bracelet or hand-sewn rubber strap, the GMT Balancier Convexe brings extraordinary mechanical complexity into refined proportions designed for improved wearability.

Greubel Forsey GMT Balancier Convexe FAQs
The Greubel Forsey GMT Balancier Convexe combines an extensive GMT and worldtime complication with the Maison’s highly architectural approach to watchmaking. Its defining feature is a miniature terrestrial globe that completes one rotation every 24 hours, providing an intuitive representation of global time. This latest evolution also introduces a more compact 42.9 mm titanium case and an integrated 72-hour power reserve, while production is limited to only 22 timepieces.
Positioned at the centre of the dial, the three-dimensional globe rotates once every 24 hours in real time. It forms part of a wider system capable of displaying local time, universal time, a second time zone and day/night information. The watch also provides worldtime across 24 time zones, together with summer and winter time indications and identification of cities observing daylight saving time, making the globe a functional part of the complication rather than simply a decorative feature.
The Greubel Forsey 30° inclined balance wheel system positions the regulating organ at an angle rather than horizontally within the movement. In the GMT Balancier Convexe, it is prominently displayed beneath a flat black-polished steel bridge and positioned alongside the small seconds indication. Beyond its technical role, the inclined balance contributes to the three-dimensional architecture that characterises the watch and allows the mechanics of timekeeping to become a visible part of the overall design.
The titanium Convexe case measures 42.9 mm in diameter and 17.6 mm in height, making it more compact than the previous version while retaining the distinctive sculptural profile of the collection. A domed sapphire crystal enhances the depth of the dial and its rotating globe, while 50 metres of water resistance adds everyday practicality. The GMT Balancier Convexe is available with either a titanium bracelet or a hand-sewn rubber strap.
