Greubel Forsey - GMT Balancier Convexe

With the GMT Balancier Convexe model, Greubel Forsey introduces a new GMT calibre that replaces all their previous GMT models. The price is €401,000

With the GMT Balancier Convexe model, Greubel Forsey introduces a brand new GMT calibre that replaces all their previous GMT models and features, for the first time, the signature inclined balance wheel.

The eye-catching titanium sphere - with its continents, seas and oceans - is 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 24 time zones displaying universal time are set against a black background if the time indicated is at night, and on a white background during the day time.

Local time is indicated on the two outer rings: one for the hours on a grey satin-finished ring, and minutes on a thin black outer ring. Each time indication has its own hand with a red triangular tip filled with luminescent material. These hands move on two further rings, engraved with key words dear to the Atelier, to display GMT. 

Finally, an off-centre display at 10 o’clock indicates a second time zone with a blue gold hand.

For the caseback of the timepiece, Greubel Forsey has kept the disc with 24 time zones indicating the UTC time of the 24 reference cities, but with a change: the UTC of Paris has been replaced by the city where Greubel Forsey has been established since its foundation: La Chaux-de-Fonds, Switzerland.

The 30° inclined balance wheel at 7 o'clock 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.

The titanium bridges, which serve as the aesthetic backdrop for this exceptional composition, are hand-finished with a steel brush and take on a frosted texture never before applied by Greubel Forsey. The delicate frosted surfaces catch the light and accentuate the globe.

The signature convex case is crafted from titanium, with a diameter of 46.5 mm around the bezel and 43.5 mm around the caseband. The height, including the synthetic sapphire crystal, is 17,40 mm. 

Water resistant to 10 ATM (100 metres / 330 feet), the watch is completed by a textured rubber strap or, alternatively, by a 3-row metal bracelet in titanium.

Greubel Forsey will produce only 66 GMT Balancier Convexe timepieces: 22 per year between 2022 and 2024. The price is Euro 401,000 / US$ 400,000 on rubber strap or Euro 447,000 / US$ 445,000 on titanium bracelet. greubelforsey.com
