Antiquorum, the world’s foremost auction house for modern and vintage timepieces, proudly upholds a legacy of excellence built on its esteemed reputation and the unparalleled expertise of its internationally renowned specialists. Founded in Geneva in 1974, Antiquorum has established a singular presence in the auction world by cultivating a vibrant global community of watch collectors. Through the consistent offering of timepieces of remarkable provenance and rarity, the house has achieved record-breaking results and regularly commands the highest prices at auction. A pioneer in horological innovation, Antiquorum made history in the early 1980s by introducing wristwatch auctions to the international market—an audacious move that redefined the landscape of collectible timepieces. This spirit of innovation continued with the advent of the thematic auction, beginning with the landmark sale “The Art of Patek Philippe” in 1989, celebrating the 150th anniversary of the legendary manufacture. Today, Antiquorum continues to host thematic sales that offer collectors not only the opportunity to acquire extraordinary pieces, but also to deepen their knowledge through meticulously researched and richly illustrated catalogues that serve as scholarly references in the field. Among the house’s most celebrated achievements, the 2005 sale “The Quarter Millennium of Vacheron Constantin” realized an exceptional USD 15,110,000 (CHF 18,123,069) , marking a record for the brand and the second-highest total ever for a single-manufacturer auction—surpassed only by Patek Philippe. Notable world records include the “Tour de l’Île” , sold for USD 1,564,000 (CHF 1,876,250) —the highest price ever paid for a contemporary wristwatch—and the “King Fouad I” , which fetched USD 2,755,000 (CHF 3,306,250) , setting a record for a Vacheron Constantin timepiece. In 2006, the renowned Mondani Collection of 309 Rolex wristwatches achieved an impressive CHF 11,037,278 , including a standout performance by the Ref. 4113 flyback chronograph, which reached CHF 738,500 —the highest auction price ever for a Rolex watch at the time. The 2007 “Omegamania” sale exceeded all expectations with a total of CHF 6,536,911 (USD 5,540,000) —three times its presale estimate. This auction set numerous records, including the highest price ever paid for an Omega watch: the 1958 “Platinum Constellation Grand Luxe” , sold for CHF 413,700 (USD 351,000) . In 2008, the thematic sale “Revolution: The Evolution of Rolex Sport Watch” brought in an exceptional USD 8,515,260 , achieving nine world records, among them the Comex Sea-Dweller , which realized a remarkable USD 248,800 . A milestone in horological history was reached in 2002, when Antiquorum established the all-time world record for a wristwatch at auction with the sale of a unique 1939 Patek Philippe World Time Ref. 1415 in platinum , which achieved USD 4,026,524 (CHF 6,603,500) —more than double the previous world record.
