My personal opinion is that with the grey dial and colorful sub dial, the grey 5960P is one of the more casual/sporty watches in Patek's lineup... which is why I think the NATO strap "works" in the first place. HOWEVER...
Just kidding of course, but it really changes the look of the watch - and not in a way that I personally would find pleasing.
On a plus side, you'll save a bundle on straps!
