About this watch

The Greubel Forsey Balancier Convexe S2 is not just a watch—it’s a horological sculpture. Crafted from grade 5 titanium, this 43mm timepiece embodies the pinnacle of modern haute horlogerie, merging radical design with uncompromising mechanical innovation. Strikingly architectural, the convex-shaped case wraps seamlessly around the wrist, enhancing both comfort and visual drama. At the heart of this kinetic masterpiece lies Greubel Forsey’s signature large balance wheel, exposed in bold asymmetry and surrounded by a three-dimensional, multi-level dial crafted with impeccable detail. This is a watch that commands attention—not through excess, but through mastery. The manual-winding movement, hand-finished to perfection, boasts a 72-hour power reserve and reflects the brand’s obsessive devotion to precision and craft. With only a handful produced, the Balancier Convexe S2 is a true collector’s piece—an icon of modern independent watchmaking. Specifications:
