GREUBEL FORSEY REIMAGINES
THE (WATCHMAKING) UNIVERSE

Could this be a return to geocentrism? With the new GMT Balancier Convexe, Greubel Forsey places the Earth back at the centre of its universe.

This new GMT calibre replaces all previous GMT models and features, for the first time, its signature inclined balance wheel, as if in orbit around the Earth.

A construction whose aesthetic architecture is matched only by its technical mastery and which confirms Greubel Forsey’s resolutely contemporary approach to Fine Watchmaking.

The Earth may no longer be the centre of the universe, as thought by Aristotle through Copernicus, but it is at the centre of Greubel Forsey’s new GMT Balancier Convexe. The perfect titanium sphere with its continents, seas and oceans, is one of the Atelier’s most emblematic creations. It was the centrepiece of the GMT, GMT Earth, GMT Quadruple Tourbillon and GMT Sport, some of Greubel Forsey’s greatest successes to date.

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.

AN EARTHLY
AMPHITHEATRE

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 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 opted to keep the disc with 24 time zones indicating the UTC time of the 24 reference cities, but with a rather appropriate modification: the UTC of Paris has been replaced by the city where Greubel Forsey has been established since its early days: La Chaux-de-Fonds, Switzerland.

HAND FINISHING PAR
EXCELLENCE

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.

The titanium bridges, which serve as the æsthetic backdrop for this horological spectacle, 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, which remains the protagonist of the arena.

Finally, the inside of the case is polished so that it mirrors the escapement platform, the Terrestrial globe, and nearly every element visible on the dial side, thus adding incredible depth to this new construction.

SIGNATURE
CONVEX CASE

This theatrical composition takes place within the signature convex case designed by Greubel Forsey. Made of titanium and with a diameter of 46.5mm 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.

Greubel Forsey will only make 66 GMT Balancier Convexe timepieces: 22 per year between 2022 and 2024.

 Perrelet presents the new "Turbine Carbon Black Edition", sporting a "Total Black"style

Decked out in black from head to toe, the "Turbine Carbon Black Edition" fully meets the expectations of watch enthusiasts who love bold yet classic and refined designs. To achieve the "Total Black" look, the case, the dial, the iconic turbine, and the strap are dyed black.

Due to its extreme lightness, this material is very pleasant on the wrist. It is also robust and boasts excellent thermal insulation capacity and resistance to chemicalagents and temperature variations. On the other hand, the bezel and case back are made of matte black PVD-coated stainless steel.

This light weight yet robust material has excellent thermal insulation capacity and resistance to chemical agents and temperature variations. On the other hand, the bezel and case back are made of matte black PVD-coated stainless steel.

The case, which has a 44 mm diameter and a thickness of 13.82 mm, has a sporty-chic look thanks to the smooth bezel and the distinctive fluted case middle. The flat matte bezel frames the black dial, which spins into action with the turbine. Perrelet’s undisputed signature, the dynamic 12-blade black anodised aluminium turbine starts rotating with every movement of the wrist

As both elements are tone-on-tone, the optical effect created during the turbine’s maximum rotation speed seems to make it vanish into thin air. Thanks to the five counterweights placed beneath the blades, when the oscillation slows down, the turbine re-emerges in all its beauty and returns to its original position.

Applied Arabic numerals and black indices are read with the central hour and minute hands. The only light notes in this dark composition are the white indications for the seconds on the flange, as well as the company logo and the Swiss Made inscription. The display is protected by an anti-reflective sapphire crystal, a material that is highly resistant to shocks and scratches.

The engine driving the “Turbine Carbon Black Edition” is the manufacture P-331-MH automatic movement beating at 28,800 vibrations per hour and offering 42 hours of power reserve when fully wound.  Recently conceived, this new-generation calibre P-331-MH benefits from substantial modifications compared to its predecessor.

The teeth of the escape wheel have an improved surface finish, and the pallet is fitted with superior quality rubies, ensuring higher performance and an impeccable degree of reliability. Furthermore, the new lubricating system of the reversers guarantees the optimum performance of the bi-directional winding system.

The balance wheel is also fitted with a double-cone Incabloc® shock absorber that increases protection against impact. Its excellent precision and reliability are guaranteed by the Chronofiable and COSC certifications obtained after successfully passing the relevant tests.

The black PDV steel case-back with sapphire crystal enables the owner to admire the circular-grained decoration on the plate and the open-worked rhodium-plated oscillating weight embellished with the Maison’s logo. To complete its “Total Black” look, the water-resistant black calfskin strap with a rubber lining is black, enlivened with grey topstitching.
