The GW-5600 series wears a little small, so I was hoping this would be a better fit. Instead, it's too big. The straps stick out where they connect to the case, so it won't lay flat against the sides of my wrist. I was hoping that being a Japanese model, it would wear a little smaller, but no luck. The one good argument for buying the import, though, is that has the multi-band feature where it receives the atomic clock time by radio each night. That's missing from the US model. Overall, I like the watch, but the lugs need to let the strap lay flatter on the sides.
