Footballer Paulo Dybala spotted wearing a Greubel Forsey

Paulo Dybala arrived at an AS Roma training session wearing what is arguably one of the most technically ambitious watches available today: the titanium Greubel Forsey Balancier Convexe S2, limited to just 66 pieces globally. Photographed giving a thumbs-up in his Roma jersey, the Argentine forward had the watch secured on his left wrist — its distinctive grey dial and structured rubber strap immediately identifiable against the bright Mediterranean sunlight.

Greubel Forsey introduced the Balancier Convexe concept as a sophisticated alternative to the tourbillon for correcting gravitational errors. The S2 variant houses the proprietary GF03c movement, a manually wound calibre beating at 21,600 vph with a 72-hour power reserve. The centrepiece is a large, inclined balance wheel set at 30 degrees within a convex architecture — visible through the skeletonised dial — designed to average out positional rate deviations across multiple orientations. Case diameter sits at 43.5mm in grade-5 titanium, keeping weight minimal despite the horological complexity within.

The Balancier Convexe S2 represents Greubel Forsey at its most accessible — relatively speaking — without abandoning the workshop's founding philosophy of solving real mechanical problems rather than chasing decorative complications. The 66-piece limitation is a direct nod to the year Robert Greubel and Stephen Forsey began their watchmaking collaboration, making each example a collectible with clear provenance. Among serious collectors, Greubel Forsey titanium pieces carry particular appeal for combining low case mass with high complication density.

Dybala, 30, has cultivated a quietly sophisticated watch collection over his career, previously spotted with pieces from Rolex and Richard Mille. His choice of Greubel Forsey signals a collector evolving beyond trophy brands toward genuine horological depth — the Balancier Convexe S2 is a watch that rewards knowledge, not just expenditure.

At a list price of approximately $216,000, the Balancier Convexe S2 commands serious money. Given the 66-piece limitation and Greubel Forsey's consistent secondary market strength, grey-market values for delivered examples have tracked close to or above retail, with little downward pressure expected as the allocation sells through.
