Collectors prioritize this reference for its 37mm stainless steel spillman-style case and the manual-wind Calibre 285 movement. The dial configuration features four sub-registers, including a \"memento\" dial at 12 o'clock intended for pilots to record a specific event time using an independent crown at 9 o'clock. This technical complication distinguishes it from standard chronographs of the era. On the secondary market, examples typically trade between $10,000 and $20,000 depending on dial originality and case sharpness. A notable production detail is the transition from early radium-luminous leaf hands to later syringe-style hands. High-condition examples with unpolished cases and original \"tropical\" or silvered dials have reached the upper end of this range at specialized watch auctions.", "score": 200}]}
