Audemars Piguet Royal Oak Chronograph (REF #25860STOO1110ST04) The first Royal Oak chronograph Ref. 25860 was released in 1998. Gérald Genta, a legendary watchmaker, presented his designs of the Royal Oak to Audemars Piguet in the 1970s. Axelrod is shown wearing a version of this watch that is the thinnest automatic chronograph calibre ever made. It is only 5.5 mm thick, with a 39mm casing. This Royal Oak carries 37 jewels and provides a 40-hour power reserve. Retail: $24,300

As a change from Audemars Piguet, Bobby Axelrod can be seen sporting a hefty Cartier Roadster reference W6206019. The watch features a 44 mm face with a thickness of 14.2 mm. The watch appears to be an anomaly in Axelrod’s collection as aside from an isolated spotting of a Rolex Daytona, the hedge fund bosses collection is largely made up of Audemars Piguet Royal Oak models.
