AUDEMARS PIGUET - "Royal Oak" Chronograph, aka Kasparov - Circa 2008 - Octagonal rose gold case with 8 screw back and engraved Royal Oak (signed and numbered). Rose gold bezel applied with 8 visible white gold screws. Silvered guilloche dial with date window at 4:30 and three dials, luminescent applied indexes and gold baton style hands. Crown and push buttons. Pink gold bracelet with original folding clasp - Signed self-winding mechanical movement - Caliber 2385 - D: 39 mm - Gross weight: 238.8 g - Audemars Piguet register extract dated March 12, 2018 and one link. Note: Watch created in 1972 and designed by Gérald Genta. The Royal Oak takes its name from the warships of the British Royal Navy. Although the first complications in the Royal Oak surfaced as early as the early 1980s, Audemars Piguet would take nearly 25 years to touch its design by housing two push buttons on the outside of its case. Faithful to the original "Jumbo" diameter of 39 mm, Audemars Piguet will succeed in housing one of the thinnest self-winding chronograph calibers ever made of its time. Often compared to the Rolex Daytona 116520 and marketed during a similar period for 14 years (1998-circa 2011), the first self-winding Royal Oak chronograph from the Audemars Piguet manufacture now out of production is a collector's watch in its own right. The model was particularly popular with chess player Garry Kasparov (Audemars Piguet ambassador since 1996), who had a close relationship with the Swiss manufacturer, and collectors went so far as to nickname this watch "the Kasparov".
