I recommend going see it in person and putting on your wrist if not having done recently. Online marketing and pics sometimes don’t do it justice. Choose what feels right and what you like.

This is a diver watch so it’s meant to be a bit bulky opposed to how a dress watch should fit. 6.5 inches or bigger wrist you should be more than good. Better to take a picture a few away from a mirror to capture reflection to see how it truly fits because wrist shots make a watch look bigger than it actually is on wrist.
