Collectors prioritize this reference as the definitive execution of Jack Heuer’s original vision for a legible racing chronograph, characterized by its 36mm stainless steel case with sharp, faceted lugs and a silver sunburst dial. It is powered by the manual-wind Valjoux 72 movement, a column-wheel caliber regarded for its durability and precision. The \"S\" designation signifies the monochromatic silver dial, which features three recessed registers and an inner tension ring with a 1/5th-second scale. Current secondary market prices typically range from $12,000 to $20,000 depending on condition and the presence of original components. A notable production variant is the \"first execution\" dial, which features thinner hour markers and hands without luminous inserts, often commanding a premium at auction due to its limited production window during the early 1960s.", "score": 200}, {"slug": "heuer-2447", "brand": "Heuer", "ref": "2447", "model": "Carrera", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/heuer-2447", "description": "Produced between 1963 and approximately 1970, the Heuer Carrera reference 2447 is a manual-wind chronograph housed in a 36mm stainless steel case with signature faceted lugs.
