Collectors value this reference for its Calibre 563, an automatic movement based on a Lemania ebauche featuring a unique instant-jump time zone complication. The 38mm case features the brand’s signature coin-edge fluting and a solid gold dial decorated with hand-guilloché wave patterns. Unlike modern world timers, the 3700 utilizes a simplified city disc system adjusted via the crown at 3 o'clock. On the secondary market, this reference typically trades between $12,000 and $18,000 depending on the presence of the original gold bracelet or leather strap. A notable production detail is the \"hidden\" signature on the dial, a security feature Breguet utilized to distinguish authentic pieces from contemporary counterfeits.", "score": 199}, {"slug": "patek-philippe-3700", "brand": "Patek Philippe", "ref": "3700", "model": "Nautilus Original", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/patek-philippe-3700", "description": "The Patek Philippe Nautilus reference 3700/1A was produced from 1976 until approximately 1990. Collectors prioritize this reference as the original \"Jumbo\" model designed by Gérald Genta, featuring a two-part monobloc case construction with a water resistance rating of 120 meters. It utilizes the ultra-thin automatic Caliber 28-255 C, based on the Jaeger-LeCoultre 920 movement. Key technical details include the 40mm diameter, a date function without a central seconds hand, and a tritium-luminous horizontal grooved dial. Current secondary market valuations typically fall within the $120,000 to $180,000 range, though exceptional examples exceed these figures. A notable production variant is the \"Albino\" prototype with a white dial, while early \"Series A\" models are specifically sought after for their integrated bracelets featuring the \"Gay Frères\" maker's mark, distinguishing them from later production runs.", "score": 199}]}
