Andy Warhol's watch collection, which included rare timepieces by Rolex, Cartier, and Piaget, was sold at a Sotheby's auction after his death in 1987.
One of Warhol's prized Patek Philippe watches, the Perpetual Calendar Reference 3448, will be auctioned at Christie's in New York on December 5.
The watch features a 39 mm case made of 18-karat yellow gold and a restored silvered dial by Stern Frères.
The dial has gold hour markers and hands, a moon display at six o'clock, and day and month windows at 12 o'clock.
The Ref. 3448 was Patek Philippe's first self-winding perpetual calendar movement and had four different dial variations.
Warhol's watch is believed to be one of only 450 made and has a last series dial.
The watch is in excellent condition and is expected to sell for $350,000 to $600,000 at the auction.
Other highlights of the auction include a Patek Philippe Sky Moon Tourbillion, an F.P. Journe Tourbillion Souverain, and a unique Richard Mille RM 018 Tourbillion.
The watches will be showcased globally before being displayed in New York's Rockefeller Center from December 1 to 4.
