Journe Tourbillon Souverain Vertical was introduced in 2019 to commemorate the 20th anniversary of the original Tourbillon Souverain. This reference remains in current production and features a 42mm platinum case housing the manual-wind caliber 1519. Unlike traditional horizontal tourbillons, this movement utilizes a vertical tourbillon cage that rotates every 30 seconds to maintain constant rate performance regardless of whether the watch is placed flat or on its side. The dial is constructed from 18k rose gold with \"Clous de Paris\" guilloché, featuring a power reserve indicator at 12 o'clock and a small seconds sub-dial. Collectors value this reference for its technical departure from the standard Souverain layout and its high-frequency rotation. On the secondary market, these timepieces typically trade in the mid-to-high six-figure range, often between $450,000 and $600,000 depending on provenance and condition.", "score": 197}, {"slug": "bovet-no", "brand": "Bovet", "ref": "NO", "model": "Fleurier Limited Edition", "case_material": "18k Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/bovet-no", "description": "The Bovet Fleurier Limited Edition NO in 18k gold was produced during the late 1990s and early 2000s as part of the brand’s revival under Pascal Raffy. Collectors target this reference for its signature Amadeo-style case, which features a 40mm diameter and a bow protector at the twelve o'clock position, mimicking a traditional pocket watch. The model typically houses a high-grade automatic movement based on the Frédéric Piguet 1150 caliber, often visible through a sapphire caseback. Dials frequently feature fired enamel or intricate guilloché patterns with Roman numerals and serpentine hands. On the secondary market, these gold models generally trade between $8,000 and $15,000 depending on the specific dial execution and condition. A notable production detail is the limited nature of these runs, often restricted to 100 or 200 pieces per dial configuration, ensuring low global supply for specific metal and color combinations.", "score": 82}, {"slug": "longines-38330", "brand": "Longines", "ref": "38330", "model": "Wittnauer Sidereal (Amy Johnson's Watch)", "case_material": "Silver", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/longines-38330", "description": "The Longines Wittnauer Sidereal reference 38330 was produced during the late 1930s, specifically around 1938 to 1940. Collectors value this reference for its specialized sidereal time complication, designed for celestial navigation by measuring time relative to the stars rather than the sun. The watch features a 33mm silver case and houses the manual-wind caliber 10.68N, modified to run approximately 3 minutes and 56 seconds faster per day than standard solar time. The dial typically includes a central rotating disc for synchronization and distinct markings for degrees and arcminutes. Due to its technical niche and limited production run, examples are rare. On the secondary market, these timepieces generally command prices in the mid-to-high five-figure range, depending on condition. A notable example is the watch worn by aviator Amy Johnson during her 1941 flight, which sold at auction for approximately $75,000 in 2019.", "score": 70}]}
