World's Most expensive watch

Henry Graves Supercomplication (1932)

Patek Philippe

$11,002,500

Sold at Sotheby's in 1999

Sotheby's experts estimated that this watch would sell for between $3 million and $5 million, but due to intense competition, bids soared to more than $11 million. With two faces and 24 complications (or functions) this yellow-gold pocket watch took four years to build and still holds the record for the most expensive watch ever sold.
