An extraordinary timepiece, celebrated for commemorating the historic moon landing. Produced in a highly exclusive run of just 300 pieces, this model in 18k yellow gold stands out not only for its rarity but also for its display case back: a unique feature allowing a view of the manual-winding calbier 861 movement. This Speedmaster is not just a collector's item but a symbol of innovation, adventure, and rarity. Owning one of these 300 pieces reresents holding a part of horological and space history.
