An exceptionally rare wristwatch, designed by Patek Philippe, is being sold at Sotheby’s New York auction with a guide price of between $300,000-$500,000.

With only 349 units produced in history between the years of 1950 and 1985 it is recognised as one of the most important wristwatches made by Patek Philippe. 

Patek Philippe and Tiffany & Co. share a remarkable history dating back to a handshake agreement between Antoine de Patek and Charles Lewis Tiffany in 1851. Tiffany formalised their handshake agreement in 1876, and the two firms have had a successful relationship ever since.

Today, Tiffany & Co. remains the only retailer in partnership with Patek Philippe, and the only firm which can still co-sign the dial of a Patek Philippe watch. 

Patek Philippe’s wristwatch will be on of the highlights of the upcoming Important Watches Auction taking place on 4 June in New York.
