Sotheby’s ten-day auction of the Collections of Andy Warhol in 1988 dispersed 179 watches the artist had owned. Some have resurfaced over the years and last year a Patek Philippe Ref. 2526 owned by the artist sold at Christie’s New York for $68,750, well above its $20,000‑30,000 estimate.

On November 11 Sotheby’s Geneva will be selling a Patek Philippe, Ref. 3448, made in 1977, and coming directly from the person who had bought it at the 1988 auction. The watch is estimated at $85,500‑128,000.
