Sam Rockwell wears a Franck Muller

Justin Hammer is what happens when you hand a mediocre engineer a defense contract and tell him he is Tony Stark. Sam Rockwell plays him in Jon Favreau's Iron Man 2 (2010) as a rival arms dealer whose attempt to outdo Stark in front of a packed Stark Expo collapses into disaster.

On his wrist is a Franck Muller. Prop Store auctioned the screen-worn watch, describing a stainless-steel Franck Muller with a black square dial and faux-silver numbers, though it recorded no specific model. The brand's watches are built to be noticed, with bold cases and oversized numerals.
