NATO Strap for Smart Watch 20mm black grey and PVD

A sixty-year-old code on a smartwatch

The black and grey stripe has crossed six decades without ever leaving the wrist. Putting it on a smartwatch sets the newest object talking to the oldest pattern. The contrast is deliberate, and it works.

Two-piece Zulu, Quick Release

Unlike the original NATO, the strap does not wrap around the case: two separate lengths fix on each side, on the spring bars. And those bars are Quick Release — a lever under the strap, a push of the nail, and it releases. No spring-bar tool, no scratched lug.

Zulu or NATO: a question of material

The Zulu is thicker, its buckle heavier: it holds a connected case better, often heavier than it looks. The weave stays dense — loose nylon sags within a summer — and the stripes are the NATO's. Buckle and keepers in black PVD rather than bright steel. 30° machine wash accepted.

Compatibility: 20mm spring bars, not Apple Watch

This strap mounts on spring bars: your smartwatch must have them — many do, some do not. Measure the gap between the lugs: 20mm and you are good. A proprietary slide or clip, and it is not possible. For the Apple Watch, no spring-bar strap mounts without an adapter: we make a dedicated version with adapters. The range varies: khaki version or orange version. All our smartwatch models are here: NATO straps for smart watches. And for a mechanical watch, our 20mm NATO straps come in the same colours, single-piece. Need a hand?
