Philippe Dufour · Grande & Petite Sonnerie

Grande & Petite Sonnerie Pocket Watch

$2,550,000

The only grande et petite sonnerie pocket watch Philippe Dufour ever made, completed in 1989 in a 60mm yellow-gold case — the first timepiece to bear his own signature after decades of building complications for other houses. A one-of-one piece of independent-watchmaking history. Sold for CHF 2,329,000 (about USD 2.55 million) at Phillips' Geneva Watch Auction: XIV in November 2021. Market-priced at auction — the figure shown reflects recent auction results.
