Greubel Forsey Balancier Convexe S2 Titanium Limited Edition

At the heart of the Balancier Convexe S2 beats the manually wound Calibre GF05, a movement entirely developed and produced in-house by Greubel Forsey. Its revolutionary architecture centers on a titanium balance wheel inclined at 30°, mounted on a convex bridge that optimizes the oscillator’s performance in all vertical positions. This patented Convexe technology, combined with a Phillips terminal curve and gold mean-time screws, ensures exceptional chronometric stability. The movement offers a generous 72-hour power reserve, operating at 21,600 vibrations per hour, and is finished to the highest standards with hand-beveled bridges, polished sinks, and frosted surfaces visible through the sapphire caseback.

The 39.6mm case is crafted from Grade 5 titanium, chosen for its lightness, corrosion resistance, and unique metallic luster. Its complex geometry features a domed sapphire crystal that follows the curvature of the movement, creating a seamless visual flow. The dial side reveals a spectacular three-dimensional landscape: the inclined balance wheel dominates at 10 o’clock, while the hours and minutes are displayed on a recessed sub-dial at 3 o’clock with a small seconds at 9 o’clock. Limited to just 11 pieces worldwide, each watch bears an individual number engraved on the caseband, underscoring its exclusivity and collector-grade rarity.

Completing this horological sculpture is a hand-stitched alligator leather strap secured by a titanium folding clasp, ensuring both comfort and security on the wrist. The Balancier Convexe S2 is not merely a timekeeper but a wearable work of art, embodying Greubel Forsey’s relentless pursuit of precision through architectural innovation. Presented as a full set with its original box and papers, this limited edition represents a rare acquisition opportunity for the discerning connoisseur. Available exclusively at SHK Watches, this timepiece invites you to own a chapter of modern haute horlogerie history.
