Antiquorum is an auctioneer of modern and vintage timepieces. Established in Geneva in 1974, Antiquorum was the first auction house to auction fine watches over the Internet in the 1990s.
The company was founded in Geneva in 1974 by Osvaldo Patrizzi and expanded to have branches in ten cities, including New York, London, Moscow, Paris, Milan, Munich, Shanghai, and Tokyo. Patrizzi sold 50% of his equity to ArtistHouse Holdings in 2006. In June 2007 he was removed by the board of directors and later filed a number of lawsuits.
Antiquorum conducts auctions in Geneva, New York and Hong Kong about ten times a year, preceded by previews in various major cities worldwide.
Antiquorum owns the Internet horology information and discussion site TimeZone.
44 of the 62 watches sold publicly by a major auction house for over SFr. 1,000,000 were sold by Antiquorum. In 2002, Antiquorum set the all-time world record for a wristwatch at auction, selling a unique 1939 platinum Patek Philippe World Time Ref. 1415 for US$ 4,026,524 (SFr. 6,603,500) - more than double the previous world record.
In March 2009, Antiquorum auctioned a number of Gandhi's possessions including his Zenith pocket watch and spectacles. This caused controversy and the Indian government tried to cancel the sale.
