During Geneva Watch Days Greubel Forsey introduced two of its Balancier Convex models in all-new carbon cases, each now measuring smaller in diameter than their existing titanium versions.

The new cases give these complex open-work watches a sleeker, sportier look when compared to their earlier counterparts. The Convexe collection is meant to be this high-end maker’s contemporary ‘daily wear’ collection, and these debuts certainly underscore that direction.

Greubel Forsey explains that making its new carbon cases required a new technical approach that includes higher temperatures and greater pressure. Since the undulating Convexe case is anything but conventional, the company’s case-makers applied eight times the amount of pressure to create these cases when compared to the amount needed to create standard cases. 

Double Balancier Convex

Now measuring 42.5 mm in diameter, 1mm smaller in diameter than an existing titanium version of the watch, this newest Double Balancier Convex retains its trademark dual and inclined balance wheels linked by a spherical differential (between 6 and 7 o’clock.)

Look for two versions of the new watch. One features an iridescent green finish matched with blue accents and a red tip on the power reserve display.

The second version of the debut is darker, with contrasts provided primarily by the signature Greubel Forsey hand-finished movement that boasts top-level mirror polishing, sharp internal angles, straight and circular-grained surfaces, and curved hands with luminescent tips.

Greubel Forsey will make the Double Balancier Convexe carbon in twenty-two pieces of each variation (black and green with matching strap). Price: $392,000. 

Balancier Convex S2

Greubel Forsey has redesigned the Balancier Convexe S2 to account for its all-new carbon case. Now fit into a 41.5mm diameter size, smaller than existing 46.5mm models, the newest edition displays a noticeably tighter set of components, which accounts for its more compact look on the wrist.

The watch’s signature double open-work arched bridge remains as the watch’s beautifully polished centerpiece, again framing the wheel train below to appear as if it is suspended in air. The architectural layout, set within the undulating Convexe case shape, features three large hand-decorated bridges and a newly blackened twin barrel cover with relief engraving.

Greubel Forsey notes that even within the new carbon-cased model, the watch has retained its traditional case, lug and crown finishes.

The watchmaker will produce the new carbon-cased Balancier Convexe S2  in two limited editions of 22 pieces each, the small seconds with blue or black treatment, matching textured rubber strap, and a titanium and carbon buckle. Price: $290,000.
