The "OAK Collection" ("One-of-A-Kind"), one of the largest private collections of Patek Philippe watches in the world, will go on display at the Design Museum in London from 19 to 25 May. The collection has been painstakingly curated over the course of almost forty years by Patrick Getreide and consists of 160 watches, including numerous Patek Philippe watches that belonged to Henry Graves Jr. (one of the largest collections outside the Patek Philippe Museum), a large collection of unique pieces commissioned by the collector or purchased at auctions of the most prestigious Houses, as well as some of the rarest Rolex, F.P. Journe and Kari Voutilainen models. A combination of vintage and contemporary watches, including Calatrava's largest collection in the world. The exhibition is divided into 11 sections, which can be described as 'chapters' of time, each encapsulating the collector's appreciation of specific types of watches - from simple three-hand models to more complicated pieces. The watches will be on display at the Design Museum for a week before going on a world tour. The Design Museum, 224 - 238 Kensington High Street, London W8 6AG. For information: designmuseum.org.
