Antiquorum

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.
In 1989 Antiquorum held a "landmark auction" called "Art of Patek Philippe." This auction helped to establish Pakek Philippe's reputation as a luxury watch brand and viable investment and solidified the notion that watches can be more than just "timepieces."
Consumer Affairs Battle
In April 2018, Antiquorum entered into a consent decree with the New York City Department of Consumer Affairs. According to the New York Post, (April 23, 2018) following numerous lawsuits, Antiquorum agreed to pay $1.5 million back to customers who had consigned their watches for sale, but had not been paid the proceeds. In addition, Antiquorum agreed to pay a $500 civil fine for operating an auction house without a license.
The New York City office is no longer listed on the Antiquorum website.
