Hi, I saw a watch on a man’s wrist yesterday which I liked, but didn’t recognize at all (not an expert...), nor had the chance to ask. The distinguishing features were - case style in steel similar to Rolex Oyster; black dial with a rather large blue circle at the 6 o’clock position - I couldn’t see if there was a hand there or other markings; the steel bracelet had chunky wide links, and the few links near the case (could be one or more) had one large perforation (hole punch) in the middle. If you have any idea I will be eternally grateful.
