Official description

The Balancier Convexe S2 redesigned in a more compact carbon case, is presented in two very limited series of only 22 pieces (each). Emphasis is placed on the technicality of carbon, the excellence of its finishes and an unprecedented diameter of 41.5mm.

Carbon is a material that Greubel Forsey has studied for many years. Giving it complex, architectural shapes, all with the highest level of watchmaking finishes, is an exercise that requires patience and technical mastery. Now, the conditions are ripe to give life to the new Balancier Convexe S2, one of the Atelier's iconic creations.

The new diameter of 41.5 mm has been specifically designed for carbon. It’s a radical change, immediately visible on the wrist. This timepiece is tighter, livelier, and even more modern. The very dark tone of the carbon reinforces the feeling of a very compact piece, while staying open to display the movement, complication and finishes.
