This is a Heavy NATO watch strap offered in 5-ring Brushed Steel for secure attachment to the wrist. Our Heavy NATO straps are made with a durable nylon material giving a tough look, but not at the expense of comfort. Strap thickness is approximately 1.5mm. Length is approximately 270mm. Although these are much more thick than our Classic NATO straps, they still maintain the comfortable feeling expected with a NATO strap. Not only is this constructed with heat-sealed ends, but also is made with stitched lining for an extra layer of protection. This is a perfect companion product for the larger watch.
