Well it looks neat, but the technical specifications don't sort of match the scuba diving situation as shown in the pictures; it only has a 10 Bar rating, which is good for skin diving and having a swim, a shower; that kind of stuff.
The movement, which is the heart of the watch, is manufactured by Seiko, which is perfectly fine, but it's not made in the USA.
I get that the bezel markings and movements of said bezel work for the sunny 16, but for anything over f/16 you appear to be guestimating. As I mostly these days use f/22 or smaller, that is a no for me!!
Actually I wouldn't purchase one, but I cannot see any problems. An old friend who was a pilot in another life, has a Rolex Navigator (I think that's what it is called) it cost him an arm and a leg about 60 years ago and is totally obsolete for it's intended purpose, but it's pretty cool when he can use his watch to work out navigation and times; or something like that.
