Our review

The Archer Classic Nylon NATO Strap in 20 mm olive is a one-piece nylon strap with an army-green look. It threads under the watch so the watch stays on your wrist if a spring bar fails. It is the classic field watch pairing. The catch is that it only fits 20 mm lugs, and the hardware at this level can be basic.

What it is

This is the olive version of Archer's classic NATO strap. NATO-style straps come from British military practice: a long nylon strap passes behind the watch and fastens with a buckle on top. The 20 mm width suits many popular field, dive and sports watches. Olive gives a green, utilitarian look that pairs especially well with military-inspired dials.

It is an accessory-level item aimed at people who want a quick change of style.

Build and materials

The strap is woven nylon with metal hardware, normally steel or a coated metal. The listing should state the finish. Nylon is light and dries quickly, so it copes well with sweat and swimming, and the colour does not suffer from water as leather would.

Olive dye can fade after months of sun and salt water, and the edges may fray. Cheaper straps in this class tend to show wear sooner than specialist ones.

Using it day to day

Pass the strap behind the spring bars, around the watch and through the buckle, then tuck the tail into the loops. The extra layer raises the watch slightly, which suits chunkier watches. It is quick to fit and remove, so swapping between straps is easy.

Measure your lug width before ordering, since the 20 mm in the name has to match. This is not the right strap for a watch with an integrated bracelet. The big benefit is the safety margin: if one spring bar fails, the strap still holds the watch.

Against the alternatives

Within the catalogue, the Archer Classic Nylon NATO Strap in black is the plainer sibling, and the WatchGecko Standard Issue Nylon Strap 20mm is the specialist alternative with a firmer reputation for finishing. The Cobee Calfskin Leather Strap 20mm and the Wocci Alligator Grain Leather Strap 20mm are leather options for a smarter look.

On a field watch such as a Hamilton Khaki or a Seiko 5 Sports, olive is a natural choice, which is why it has become the classic pairing.

Olive is less versatile than black, though. It looks wrong against a formal dial and can clash with cool-toned steel cases, so think about what you will wear it with before choosing.

Who it's for, and who should skip it

It suits someone with a 20 mm sports or field watch who wants to try a new look without spending much. It is good for holidays, hiking and swimming.

Skip it if your watch's lugs are not 20 mm apart, if it has an integrated bracelet or if you need a dressy strap. The honest drawback is that cheap hardware may tarnish and the fabric may fray in time.
