Jim Carrey wears an unidentified watch

Jim Carrey wears a steel watch as Walter Sparrow in The Number 23 (2007). Raising a hand toward his face, he shows a round steel case with a dark dial on his left wrist, on a dark strap. The dial's in shadow with no branding I can read, so the model stays open. Recognise it, or want to take a guess? Tell us in the comments.
