I'm losing money here but it's too big on my 6.5" wrist. Thought I could pull it off but I was wrong. 6.75 or larger should be fine. The watch is in new condition and it's stunning with the large sapphire crystal, large markings and awesome lume! These are no longer made and this is one of the last chances to get a new one. $460 shipped to USA/Canada, make me an offer!
