My feeling is that the watch head of an SA would be too heavy for a NATO really, and that the watch might swim a bit on the wrist.

wear them almost exclusively on my seawolf. this company has the best customer service and fit and finish i've found yet: http://www.europelli.com/Zulu-and-NATO.html

I really love the look of NATO straps, however what puts me off is the extra strap just kind of hangs out, even when tucked in it just doesn't look right to me. If I found one that wasn't super long I would probably get a few.

The benefit of fitting a one piece NATO is that if one spring bar lets go the watch won't fall off your wrist so a good safety option if you're diving or indulging in some other activity where your watch could disappear beyond reach!

Matt, I feel that the extra strap would drive me crazy too. but the website I ordered them from changed the way they are made and the positioning of the buckles apparently from their old strap. They say it should eliminate the extra portion of it by tucking it into itself so you really cant see it. But they are in the business of selling straps. So we will see.

The only diving I get around to is desk diving while I am perusing BS.

But I def see your point. Never know what the day will throw at you.

Well it could drop into your coffee or even the shredder..................I've never had a spring bar let go but if one did whilst I was sailing I'd be doing a sight more than desk diving to get my watch back.
