The Seiko Prospex GMT SPB381J1 is spectacular GMT watch that is sure to stand out. 

With it's 42mm diameter case (excluding crown) and 12.9mm thickness the SPB381J1 is suitable for most wrists. Of course the watch is water resistant to 200m and the beautiful dial is protected by a sapphire crystal. The movement powering all this is the Seiko Cal. 6R54 GMT movement, which has an incredible 72 hour power reserve, a full three days! This watch simply does it all, take it diving while tracking a second time zone and do it all while looking amazing!
