Shia LaBeouf wears an IWC Portugieser

Oliver Stone's Wall Street: Money Never Sleeps (2010) follows Jacob Moore, a young trader at a Wall Street investment bank who is engaged to Gordon Gekko's estranged daughter and trying to make it in finance without becoming Gekko. Shia LaBeouf plays Moore. Michael Douglas returns as Gekko, out of prison and circling the action, and Josh Brolin plays the rival banker Bretton James.

The watch on Moore's wrist is an IWC Portugieser Perpetual Calendar, reference IW502303, and IWC put it there. The company announced it had landed its watches on both leads, Moore's Portugieser and Gekko's rose-gold Da Vinci Perpetual Calendar. The Portugieser is not a simple watch. It is a perpetual calendar, a movement that tracks the date, the day, the month and the phase of the moon, and adjusts for the length of every month and for leap years on its own. In the still here, Moore at his desk with a pen in one hand, the dial shows it plainly: four small registers arranged around the center, one of them carrying the moon. That is the calendar, not a chronograph.

The Portugieser name goes back to 1939, when two Portuguese importers asked IWC for a wristwatch as accurate as a marine chronometer, and IWC answered by fitting a large pocket-watch movement into a wrist case. That is why the watch is big and clean-faced. For a character meant to read as serious about his craft, it is a pointed thing to wear: the most complicated watch IWC makes, on the youngest man in the room.
