Vincent Cassel wears an unidentified watch

Vincent Cassel wears a steel dress watch as Thomas Leroy in Black Swan (2010). The close view shows a round steel case with a black dial, applied baton markers and a date window at three, on a black leather strap, a sleek piece for the company's imperious director. I can't read the maker on the dial, so it stays open. Recognise it, or want to guess? Drop it in the comments.
