Collectors prioritize this reference for the Calibre 1120 QPSQ/1, a skeletonized, self-winding movement measuring 4.05mm thick within an 8.1mm pink gold case. The open-worked dial features 18k pink gold hour markers and circular-grained finishes, maintaining a 50-meter water resistance rating despite its slim profile. It includes the brand’s proprietary interchangeable strap system with a gold bracelet, rubber, and leather options. On the secondary market, this model typically trades in the $140,000 to $180,000 range, though prices fluctuate based on inventory. A notable production detail is its 2020 Grand Prix d’Horlogerie de Genève (GPHG) win in the Calendar and Astronomy category, which solidified its status as a technical benchmark for the Overseas collection.", "score": 200}]}
