I am a big fan of the NATO strap. My favorite on Amazon is the Art Style brand. They are better made and more durable than the typical NATO strap.
I got a couple of these, and they seem quite alright. They're a 5-ring type, which is probably about 2 rings too many. When I wear them the "proper" way, they're just barely long enough. Which is fine, since I don't want a lot of extra strap to deal with. I thought my wrists were fairly average.
The Proper Way:
Or so says the internet. At least it gives that fifth ring something to do.
These watch bands have changed my life, though. I find myself changing them out, to coordinate with what I'm wearing. It's fabulous!
