Protecting the Consumer and Servicing
the Trade with Independence and Integrity

The most complicated handmade watch, the Henry Graves Supercomplication, has been sold at auction for 20.6m Swiss francs (£13.4m). A "complication" is a technical term referring to any feature on a watch which is in addition to simply telling the time. The Supercomplication, made by Patek Philippe in 1932, has 24 of them including Westminster chimes, a perpetual calendar, sunrise and sunset times, and a celestial map of New York as seen from Graves's apartment on Fifth Avenue.

Most complicated watch

Graves commissioned the Supercomplication watch in order to compete against the automotive pioneer James Packard, who owned a watch with 10 complications. The Supercomplication has 900 parts and remains the most complicated watch built without the assistance of computers, according to Sotheby's. It was last wound in 1969. And it's still working.
