A Story in Nylon

Hardly any watch accessory has a name that is so thoroughly misunderstood. Most people assume the NATO strap takes its name from NATO itself—the military alliance that supposedly designed or commissioned it. That is not entirely true. The real story is more inconspicuous, more British, and actually even more interesting.

The true origin

In 1973, the British Ministry of Defence published a new standard for equipment, Def Stan 66-15, titled simply "Strap, Wrist Watch." The requirement was for a robust watch strap, simple to manufacture and easy to replace, that would function reliably in field operations. The result was exactly the strap known today as the "NATO." It is 280 mm long, 20 mm wide, made of tightly woven nylon, and features chrome-plated brass hardware.

The name was not derived from NATO as an organization, but rather from an administrative detail. The strap was tracked in the British supply system with a NATO Stock Number, a numbering system that many NATO armed forces used collectively to catalog equipment. Colloquially, this stock number became "the NATO strap." Among military personnel, another name took hold anyway. They called it the G10, named after the G1098 form that a soldier had to fill out to requisition one from the supply depot.

Better safe than sorry

What technically distinguishes the strap is a simple yet clever trick. Instead of a single strip of fabric, it consists of two layers of nylon, both of which run underneath the watch case. If one of the two spring bars breaks, the watch remains attached to the wrist, held by the second bar. For a piece of equipment that could not be lost in the field, this was not just a detail, but the actual function.

The Bond myth that isn't one

One image has become particularly deeply etched in the collective memory: Sean Connery appearing in "Goldfinger" in 1964 with a striped Rolex Submariner on his wrist. Many recount this moment as the birth of the NATO strap. Chronologically, that is simply impossible, because the film was released nine years before the actual Def Stan standard. What Connery wore was a simple, single-layer nylon strip, not a genuine G10 construction. Nevertheless, this image did popularize something: the striped look, which is still associated with the NATO strap today, even though the original was simply in Admiralty Grey. The colored stripe patterns were added later when individual regiments wanted to wear straps in their respective unit colors.

From the field to everyday life

What began as purely practical has since developed far beyond its military origins. Lightweight, quick to change, and resistant to water and weather. The same qualities that made it useful for the military now make it an obvious choice for anyone who wears a watch daily instead of just owning it.

That is exactly what interests us about the NATO strap. It is not a piece of jewelry that needs to be pampered, but rather a piece of thoughtful, honest functionality and a history worth telling properly.
