Collectors prioritize this reference for its use of the Valjoux 72 column-wheel movement and its minimalist dial design, which removed non-essential scales to improve legibility for drivers. The model is categorized by dial configurations, including the 2447N (black), 2447S (silver), and the 2447NST or 2447SNT featuring contrasting sub-dials. Current secondary market prices typically range from $12,000 to over $25,000 depending on condition and specific execution. A notable variant is the early \"first execution\" dial, distinguished by thinner hour markers and hands, which often commands a premium at auction. These watches represent the initial generation of the Carrera line, established before the transition to automatic movements in 1969."}, "listing_stats": {"count": 33, "median": 5900.0, "low": 3650.0,
