NATO and Zulu straps are great for many reasons. The main being the failsafe feature of securing your strap in case of spring bar failure. For those of you with valuable watches or those who just love the style I have what you need.
Please keep in mind these are leather straps and some have accent stitching that run the length of the strap. It is very bad for the leather and stitching to be pulled through the spring bars. I recommend installing the strap by removing the spring bars first, placing the strap between the lugs, then reinstalling the bars. This is still much easier than putting on a two piece or bracelet and guarantees to preserve the quality of your strap.
