Greubel Forsey | Collection Convexe | GMT Balancier Convexe

An evolution of the GMT Balancier Convexe — more compact, more complete, and more precisely resolved than its predecessor. The case is reduced. A power reserve display is integrated. The architectural logic of the movement is pushed further.

At the centre of the dial sits a miniature terrestrial globe, rotating in real time over 24 hours. It sits flush with the sapphire crystal, surrounded by concentric layers of indication: local time, universal time, a second time zone, and a day/night distinction. The architecture is built around this rotating earth — not decorative, but functional at every level.

02 / 05

The 30° inclined balance wheel is suspended beneath a flat black-polished steel bridge, flanked by a small seconds display. The newly integrated 72-hour power reserve is positioned without disrupting the compositional balance of the dial.

The movement is housed in the Convexe titanium case at 42.9 mm — reduced from the previous version for improved wearability while preserving the architectural profile that defines the line. The domed sapphire crystal and three-dimensional bezel maintain the sculptural character. Available on a titanium bracelet or hand-sewn rubber strap.
