Collectors prioritize this reference for its historical significance and the Valjoux-based Caliber 13-130 movement. Of the 281 total units produced, the majority were cased in yellow gold, while approximately 58 examples were executed in 18k pink gold. These pink gold variants often feature \"pink on pink\" configurations with matching rose-toned dials. The case measures 35mm and features square chronograph pushers and a snap-on back. On the secondary market, 18k pink gold examples typically command between $1,200,000 and $2,500,000 depending on dial condition and provenance. A notable production variant includes the rare transition from the \"long\" signature to the shortened \"Patek Philippe\" branding on the dial. In 2021, a pink gold 1518 with a pink dial achieved a sale price exceeding $3,000,000 at auction.", "score": 199}, {"slug": "hublot-1915", "brand": "Hublot", "ref": "1915", "model": "Classic Fusion", "case_material": "18k Pink Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/hublot-1915", "description": "The Hublot Classic Fusion 1915 in 18k pink gold, specifically reference 1915.GP.10.7, was produced during the mid-to-late 2000s and is no longer in current production. Collectors target this reference as a bridge between the original 1980s MDM designs and the modern Big Bang era. It features a 41mm 18k pink gold case with the signature integrated black rubber strap and a minimalist black dial with gold indices. The watch is powered by a modified ETA-based automatic movement, often the Caliber HUB11, which offers a 42-hour power reserve. This model is valued for its thinner profile compared to the Big Bang and its adherence to the brand’s \"Art of Fusion\" origins. On the secondary market, this reference typically trades between $8,000 and $12,000 depending on condition. A notable production detail is the use of the early \"Hublot Geneve\" dial branding, which distinguishes it from later Classic Fusion iterations.", "score": 72}, {"slug": "patek-philippe-1415", "brand": "Patek Philippe", "ref": "1415", "model": "World Time", "case_material": "18k Yellow Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/patek-philippe-1415", "description": "The Patek Philippe Reference 1415 was produced from approximately 1939 until 1954, representing the brand’s first world time model made in series. Collectors value this reference for its manual-wind Caliber 12-120 HU movement and the Louis Cottier-designed rotating bezel engraved with city names, which allows for simultaneous timekeeping across twenty-four zones. The 31mm 18k yellow gold case features teardrop lugs and a hand-guilloché or silvered dial. Production was limited, with an estimated 82 yellow gold examples identified to date. On the secondary market, prices typically fall within the mid-to-high six-figure range, though exceptional examples can exceed one million dollars. A notable production variant includes the rare cloisonné enamel dial versions; one such example in yellow gold achieved a sale price of approximately 1.2 million CHF at a 2021 auction, reflecting the premium placed on decorative dial variations within this reference.", "score": 72}]}
