The NATO strap, born from a military specification
The NATO strap appeared in 1973, at the request of the British Ministry of Defence. Its standard name: G10. The specification came down to two words, reliability and strength. Made famous on James Bond's wrist in Goldfinger, it has become a collector's accessory. The full story in our article on NATO strap history and origins.
One piece, two spring bars: the security of the NATO strap
A NATO strap is made in one piece. It passes under the case, between the two spring bars, then wraps around the wrist. If one spring bar fails, the watch stays held by the other. The nylon resists water and sweat, and is machine washable at 30°C. It suits a diving watch as well as a vintage chronograph.
Choosing the width by lug width
The strap width matches your watch's lug width, the distance between the lugs of the case, measured in millimetres. The 18mm NATO strap suits slim dress watches. The 20mm NATO strap is the most common width, that of the Rolex Submariner or the Omega Speedmaster. The 22mm NATO strap fits larger sports watches, the 24mm NATO strap oversized cases. For less common lug widths, see our 19 and 21mm NATO straps. Our lug width chart by watch model lists the width of 272 watches from 47 brands.
Stainless steel buckle and keepers
All our NATO straps come with a pin buckle and keepers in anti-corrosion stainless steel. The nylon, around 1.5 mm thick, has woven edges, soft against the wrist.
Colours for every watch
From black and military khaki to film-inspired stripes (Gulf blue and orange, James Bond black and grey) and summer shades. A NATO strap changes in seconds, without tools: the same watch takes on a new look from one day to the next. For the combat swimmers' model, the elastic Marine Nationale 20mm version completes the range.

NATO strap FAQ
What is a NATO strap?
A NATO watch strap is a single-piece nylon strap that passes under the case, between the two spring bars. It was created in 1973 at the request of the British Ministry of Defence, under the G10 standard. If one spring bar fails, the watch stays held by the other.
Which NATO strap width should I choose?
Measure the space between your watch's lugs, where the strap attaches: that is your width, in millimetres (18, 20, 22 or 24 mm). Our NATO straps suit Rolex, Tudor, Omega, Seiko, Hamilton, Sinn, Longines, Oris or Panerai, among others. Always check the lug width before ordering, for instance in our strap width chart by watch.
How long is a NATO strap?
Our NATO straps are 280 mm long, the length of the original G10 standard. Once buckled, the excess folds into the last keeper.
Which NATO strap size for my wrist?
One size fits all. At 280 mm, a NATO strap fits wrists from 15 to 20 cm: adjust it at the buckle, then fold the free end into the last keeper. Only the width matters.
What makes a good NATO strap?
A good NATO strap comes down to four points: single-piece G10 construction, dense nylon, woven edges, and a stainless steel buckle and keepers. Our NATO straps combine all four: nylon around 1.5 mm thick, soft woven edges against the wrist, anti-corrosion stainless steel buckle and keepers.
What is the original NATO strap colour?
The original military NATO strap is grey, a shade known as Admiralty Grey. For the historic model, choose our Admiralty Grey 20mm NATO strap.
Do you need a tool to change a NATO strap?
No. A NATO strap slides under the spring bars already in place: it goes on and comes off in seconds, without removing anything.
Is a NATO strap water resistant?
Yes. The nylon resists water and sweat, and the stainless steel buckle and keepers do not corrode. The strap is machine washable at 30°C.
Can I fit a NATO strap on a Rolex?
Yes, on Rolex models with a 20 mm lug width, such as the Submariner, GMT-Master or Daytona: choose a 20mm NATO strap. Check your model's lug width before ordering.
Are there leather NATO straps?
Yes. Our Arezzo leather NATO straps, designed in collaboration with the brand and made in Tuscany from Tuscan leather, are lined and less than 2 mm thick. They slide under the spring bars like a nylon NATO, with the look of leather. Available exclusively online: the Arezzo black leather 20mm NATO strap, and the full collection of Arezzo leather straps.
