NATO and nylon strap guide
Why a nylon strap on a field watch
Woven straps dry fast, weigh almost nothing and do not mind sweat, rain or dust. That is why they became the default on service watches after WWII, and why they still suit a field watch you wear every day. The range here covers three styles: the Black "Invasion" NATO, a one-piece strap that passes under the case; the Brown Nylon strap; and the Olive Green Perlon, a braided strap whose buckle pin goes through the weave, so it adjusts to any wrist size.
Fitting and care
Match the strap width to the inside gap between the lugs of your watch. To change a strap, push the spring bar in with a strap tool, slide the old strap out and fit the new one. Nylon and Perlon can be hand washed with mild soap and left to air dry.
NATO and nylon questions
What is the difference between a NATO and a two-piece nylon strap?
A NATO is one long piece that passes under the case, so the watch stays on the wrist even if one spring bar fails. That extra material makes the watch sit a little higher. A two-piece strap attaches to each lug separately and leaves the caseback against your wrist for a thinner fit.
What is a Perlon strap?
Perlon is a braided nylon strap. The buckle pin goes through the weave rather than fixed holes, so you can fine-tune the fit. It's useful when one hole on a regular strap feels too tight and the next feels too loose.
Can I wear a nylon strap in water?
Yes, but a water-friendly strap doesn't make the watch suitable for swimming. Check the watch's water-resistance rating first. After salt water, rinse the strap with fresh water and let it dry fully before wearing it again.
