The Patek Philippe Henry Graves Supercomplication (no. 198.385) is one of the most complicated mechanical pocket watches ever created. The 18-karat gold watch has 24 complications and was assembled by Patek Philippe.[1][2] It was named after banker Henry Graves, Jr., who supposedly commissioned it out of his desire to outdo the Grande Complication pocketwatch of American automaker James Ward Packard.[1][2][3] The two were both at the top of the watch collecting world, regularly commissioning innovative new timepieces.[4]
