NATO CONCEPT grey 20mm bracelet nato

Anthracite, between grey and black

Anthracite settles an old argument: black is too hard, grey too soft. It sits exactly between them. With polished steel, it is the most dressed-up strap in the NATOCONCEPT line.

The NATOCONCEPT line

The NATOCONCEPT is not a standard NATO strap. The buckle and keepers are polished stainless steel, not brushed: light catches them the way it catches a watch clasp. The nylon is more tightly woven and the strap is supple from the first fitting. This is our premium line.

What separates a good NATO from a bad one

Three points, nothing else. Weave density: loose nylon sags within one summer. Steel quality: cheap steel turns your wrist green. And the finish of the ends: poorly heat-sealed, they fray. That is where the price of a NATO strap is decided.

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°.

Few customers stop at one: see the 20mm bordeaux NATO strap or the 20mm black NATO strap. To move up, look at the Arezzo leather NATO straps. The full width is here: 20mm NATO straps.
