The Patek Philippe Henry Graves Supercomplication (no. 198.385) is one of the most complicated (and most expensive) mechanical pocket watches ever created. The 18-karat gold watch has 24 complications and was assembled by Patek Philippe. 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. “Supercomplication” is not an exaggeration. Patek Phillipe bills this as the most complicated watch ever made without the help of computer design and manufacture. Commissioned in 1925 and finally delivered to banker and watch collector Henry Graves to exactly that end, this one-off piece packs in 430 screws, 110 wheels, and 70 jewels among its 920 individual parts.
Henry Graves, Jr., was a New York banker and avid watch collector who, legend has it, was engaged in a competition with fellow tycoon James Ward Packard (of Packard Motors) to become the owner of the world’s most complicated watch. In 1933, the timepiece that Graves commissioned from Patek Philippe, aptly named the Henry Graves Supercomplication, earned that distinction with its 24 complications, blowing away the 10 complications of the watch Patek had made for Packard in 1927. The array of horological functions built into the unique, gold pocket watch include Westminster chimes, perpetual calendar, sunrise and sunset times, and a celestial map of New York as seen from Graves’s Fifth Avenue apartment. After Graves died in 1953, the watch changed hands several times throughout the years, and was auctioned for the first time by Sotheby’s in 1999, bought for a then-record price of $11,002,500 by Sheikh Saud bin Mohammed Al Thani of the Qatar Royal Family. After his death, the watch was auctioned again by Sotheby’s in 2014, sold to an anonymous buyer and breaking another record.
