Harrison Ford wears an IWC Pilot's Watches

Firewall (2006) hands Harrison Ford a banker's nightmare: criminals take his family hostage and order him to move a hundred million dollars out of the Seattle bank he was hired to protect. At one point director Richard Loncraine holds the camera on Ford's wrist long enough to read the dial - IWC SCHAFFHAUSEN at twelve, MARK XV AUTOMATIC above six, the date at three.

This is the IWC Mark XV, reference IW325301 in its black-dial form: a 38mm steel pilot's watch with luminous Arabic numerals, an ETA-based automatic movement, and a soft-iron inner case that shields the movement from magnetic fields. IWC launched the Mark XV in 1999 to replace the Mark XII, and the line runs back to the Mark XI, introduced in 1948 and built for the Royal Air Force - a navigator's watch made to stay legible and accurate near the magnetic fields of a cockpit.

Ford holds both fixed-wing and helicopter pilot licenses, so the pilot's watch on his wrist is one he could plausibly wear off-screen too.
