No idea; could be nonsense. Although I thought he wore a Seamaster in another film, but I can't remember which that was either. Then again, it wouldn't be surprising if he wore more than one in a movie. Product placement wasn't the industry it is now.
The only thing I'm sure of is that 99% of the internet is pulled out of somebody's ass. Whether it's my link or your link falling into that category I really can't be bothered to find out. But I'll assume it's both! Sorry for the digression, and doubly so if it's actually bullshit. :)
