This reference features the brand’s first central flying tourbillon, powered by the manual-wind caliber HUB9015 with a 150-hour power reserve. The 42mm case is constructed from polished clear sapphire, shaped into Murakami’s signature twelve-petaled flower motif. The dial is integrated into the movement architecture, surrounded by 444 gemstones including rubies, sapphires, and amethysts set into the petals. Collectors value this reference for its technical departure from standard Hublot layouts and its status as a one-of-one prototype for the subsequent limited production series. While the retail estimate was approximately $350,000 to $400,000, it sold at auction for 420,000 CHF. On the secondary market, unique Only Watch pieces typically command mid-to-high six-figure prices depending on private sale negotiations.", "score": 198}, {"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": 83}, {"slug": "omega-2915-2", "brand": "Omega", "ref": "2915-2", "model": "Speedmaster", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/omega-2915-2", "description": "The Omega Speedmaster reference 2915-2 was produced between 1958 and 1959 as the second iteration of the original Speedmaster line.

The 39mm stainless steel case retains the symmetrical straight-lug design without crown guards and includes a steel tachymeter bezel, a feature unique to the 2915 series before the transition to black aluminum inserts. Rarity is high due to the short production window. On the secondary market, prices typically occupy the mid-to-high six-figure range depending on the presence of original components like the \"Base 1000\" bezel. A notable auction result occurred in 2021 when a tropical-dial 2915-1, the immediate predecessor sharing most 2915-2 specifications, sold for over 3 million USD, though standard 2915-2 examples generally command lower premiums.", "score": 83}, {"slug": "omega-2915-1", "brand": "Omega", "ref": "2915-1", "model": "Speedmaster Broad Arrow", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/omega-2915-1", "description": "The Omega Speedmaster reference 2915-1 was produced between 1957 and 1958 as the inaugural model of the Speedmaster line.

It is characterized by a 39mm symmetrical stainless steel case without crown guards, a matte black \"Base 1000\" metal bezel, and \"Broad Arrow\" handset. The watch is powered by the manual-wind Calibre 321 movement. Due to a short production window, surviving examples in original condition are rare. On the secondary market, prices typically range from the mid-six-figures to over $1,000,000 for exceptional specimens.

It utilizes the Calibre 1137, a column-wheel chronograph movement based on the Frédéric Piguet 1185, distinguished by a large date display at the 12 o'clock position. The dial is characterized by a \"Guilloché\" pattern composed of repeating Maltese crosses.
