Greubel Forsey has reworked the original Balancier S into a new, bolder form focusing on contrast and power in the Balancier Convexe S². It shares the same movement with its distinctive 30º angled balance wheel, yet the case and finishing have been reworked to modernize it. With increased legibility due to the intense new background cutting through the balance bridge between 5 and 9 o’clock and slightly larger diameter, the Balancier Convexe S² takes its rightful place in the ranks of Greubel Forsey ingenuity. Limited to 66 pieces of each iteration.
