Collectors value this reference for its chronometer-certified Calibre 478BWSbr movement, which features a hacking seconds mechanism, a Glucydur balance, and a swan-neck regulator. The 35mm stainless steel case includes an inner soft-iron cage for anti-magnetic protection up to 600 gauss. Production was limited, with approximately 1,038 steel units manufactured. The dial typically features luminous plots on the inner bezel or \"crosshair\" markings, though variations exist. On the secondary market, these watches generally trade in the $20,000 to $40,000 range depending on condition and dial configuration. A notable variant is the \"Publicité\" dial, which lacks the Geophysic branding, while a well-preserved example reached approximately $67,000 at a 2017 Phillips auction, reflecting the premium placed on original luminous material.", "score": 199}, {"slug": "audemars-piguet-16869", "brand": "Audemars Piguet", "ref": "16869", "model": "Grosse Pièce", "case_material": "18k Yellow Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-16869", "description": "The Audemars Piguet reference 16869, often referred to as the Grosse Pièce, was produced in the early 1990s as a limited series of approximately 50 units. Collectors value this reference for its oversized 40mm 18k yellow gold case, which was unusually large for the era, and its use of the caliber 2120/2802. This ultra-thin automatic movement features a perpetual calendar with a leap year indicator and a moon phase. The dial typically features a white porcelain-like finish with recessed sub-dials and stick markers. Due to its limited production run and historical significance as a precursor to the modern oversized luxury watch trend, the reference 16869 occupies a niche position in the brand's heritage. On the secondary market, these timepieces generally command prices in the mid-to-high five-figure range, with exceptional examples occasionally reaching the low-six-figures at international auctions.", "score": 72}, {"slug": "rolex-1680", "brand": "Rolex", "ref": "1680", "model": "Submariner Prototype", "case_material": "18k White Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/rolex-1680", "description": "The Rolex Submariner reference 1680 in 18k white gold is a prototype produced in the early 1970s, specifically around 1973. This reference was never released for commercial production, as the standard gold Submariner of that era was manufactured exclusively in yellow gold. Collectors value this piece for its extreme rarity and its departure from standard production materials, featuring a 40mm white gold case and a matching white gold Oyster bracelet with a hidden clasp. It utilizes the COSC-certified caliber 1570 movement and typically features a blue \"nipple\" dial and a blue rotating bezel insert. Due to its status as a prototype with only three known examples identified publicly, it occupies a high-six-figure to low-seven-figure price bracket. A notable auction result occurred in 2017 when a confirmed example sold for approximately $630,000, establishing its position as one of the most expensive vintage Submariners.", "score": 72}]}
