Hidden for decades, two extraordinary Patek Philippe watches from the Olmsted Collection have reemerged, each with twin movements, twin balances, and twin time displays that defy every rule of early 20th-century watchmaking.

Join Sotheby’s Watches specialists as they decode one of horology’s most perplexing masterpieces ahead of Important Watches featuring Exceptional Discoveries: The Olmsted Complications Collection, taking place 8 December in New York, part of Luxury Week presented by EDITION Hotels.
