NATO Strap bleu and line red yellow 20mm

Blue with two pinstripes

Blue base, yellow line, red line: a combination straight out of the paddock. It works on chronographs, less so on dress watches. Commit to it or move to plain navy.

Which width for your watch?

Measure the gap between the lugs, not the case diameter: it is the only figure that decides. At 20mm this strap fits with no play. A NATO strap passes under the case, so it can be narrower than the lug width, never wider.

One piece of nylon, no joining seam: the original G10 construction. The strap runs under the case, bears on both spring bars and loops back on itself. Marine-grade anti-corrosion stainless steel buckle and keepers, unaffected by salt. Machine wash at 30°.

Fits 20mm lug width

IWC Mark XVIII, Doxa Sub 300, Marathon GSAR, Marathon TSAR, Oris Divers Sixty-Five 40. 20mm is the most common lug width on the market: measure the gap between your lugs to confirm.

Colour on the wrist

Few customers stop at one: see the 20mm black blue white red NATO strap or the 20mm GULF NATO strap. To move up, look at the NATOCONCEPT white with orange line. The full width is here: 20mm NATO straps.
