Antiquorum is offering up some exceptional timepieces at its April 10th event in New York City. The "Important Modern & Vintage Timepieces" auction will feature some extraordinary watches, highlighted by a rare Patek Philippe Ref. 1518 (pictured above) that was manufactured in 1951. The watch includes an unusual pink-gold bracelet, perpetual calendar, moon phases, and a tachometer. It's expected to go for as much as $600,000 USD.
Also of special note is the Audemars Piguet Grande Complication Automatique in titanium from 2002 (see below). This self-winding wristwatch features a co-axial round button split-seconds chronograph, perpetual calendar with indication of the weeks and moon phases, an original fitted winding box that include two spare dials, and a signed letter from Georges Henri Meylan, former President of Audemars Piguet, verifying that this Grande Complication was the first titanium example kind ever produced. It's estimated to sell for as much as $300,000 USD.
The auction will be held on Wednesday, April 10, 2013 starting at 10AM EST at 595 Madison Avenue in New York City. For more information, please visit Antiquorum.
