The watch for collectors drawn to audacity and technical depth. This Girard-Perregaux Opera II ref. 99741, produced in platinum in limited numbers, unites three major complications. It features a one-minute tourbillon, perpetual calendar, and a Westminster minute repeater with carillon chimes in a 42mm case. The manual-wind Caliber GP9899 is partially revealed on the cream dial, with apertures exposing the tourbillon cage and the repeater gongs between 8 and 10 o'clock. Weight, scale, and complexity define its presence, reflecting the brand's willingness to challenge traditional design codes. This pre-owned Girard-Perregaux Opera II Perpetual Calendar Tourbillon Platinum Watch 99741 includes a gift box.
