Collectors prioritize this reference for its Valjoux-based manual-wind caliber 727 and the inclusion of screw-down chronograph pushers, which increased water resistance compared to earlier pump-pusher models. The \"Big Red\" designation refers to the oversized red \"Daytona\" text curved above the six o'clock sub-dial, a specific dial configuration highly sought after for its visual distinction. The watch features a black acrylic tachymeter bezel and a 37mm Oyster case. On the current secondary market, prices typically range from $100,000 to over $150,000 depending on condition and provenance. A notable production variant is the \"Sigma\" dial, which features small Greek letters at the bottom to indicate the use of solid gold hour markers, often commanding a premium at auction.", "score": 199}, {"slug": "blancpain-6263-3642-55b", "brand": "Blancpain", "ref": "6263-3642-55B", "model": "Villeret Quantième Complet", "case_material": "18k Pink Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/blancpain-6263-3642-55b", "description": "The Blancpain Villeret Quantième Complet reference 6263-3642-55B is a 38mm complete calendar moonphase timepiece cased in 18k pink gold. This reference was introduced in the early 2000s and remained a staple of the Villeret collection for over a decade before being superseded by larger 40mm iterations. Collectors value this model for its traditional proportions and the caliber 6763 automatic movement, which provides a 100-hour power reserve. The dial features an opaline finish with applied Roman numerals and the signature \"smiling\" moonphase indicator at six o'clock. Unlike later versions featuring under-lug correctors, this reference utilizes recessed pushers on the case flanks for calendar adjustments. On the secondary market, this reference typically trades between $9,000 and $13,000 depending on the presence of the original box and papers. A notable production detail is the use of a stepped \"double pomme\" bezel, a hallmark of the Villeret design language.", "score": 84}]}
