James Marsden wears an unidentified watch

James Marsden wears a watch as David Sumner in Straw Dogs (2011). Sitting by the car, he has it on a brown crocodile-style leather strap, with the case turned to the inside of his wrist so the dial doesn't show. There's nothing readable, so the maker stays open. If you know what the screenwriter is wearing, or want to guess, say so in the comments.
