NATO straps have earned their place as a favourite among watch enthusiasts. Originally designed for the British Ministry of Defence in the 1970s, they were built for security, comfort, and reliability. Today, they’re just as popular for their rugged style and easy installation.

Unlike two-piece leather or metal bracelets, a NATO strap is one continuous piece of nylon that threads under the watch case. This design not only keeps the watch secure but also makes swapping straps quick and tool-free.

Here’s your complete guide to installing a NATO strap the right way.

Refer to the video at the end of this article.

1. What You’ll Need

• Your watch (with spring bars installed).
• A NATO strap of the correct lug width (commonly 18mm, 20mm, or 22mm).
• Spring bar tool (optional, only needed if you’re removing an old strap).
• Spare spring bars (recommended, in case your old ones are worn).

👉 Pro Tip: At TAGSTHX, we always recommend checking your spring bars for wear. Fresh bars mean better security.

2. Remove the Old Strap

If your watch currently has a leather, rubber, or metal bracelet:

1. Use a spring bar tool to compress the bar.
2. Gently remove the strap from the watch lugs.
3. Leave the spring bars in place—you’ll need them for the NATO strap.

💡 Optional: Replace old or weak spring bars before installing your new strap.

3. Orient the NATO Strap

This step is often missed: the buckle of your NATO strap should sit on the 12 o’clock side of the watch (the top of the watch). This way, when worn, the buckle naturally falls on the underside of your wrist for comfort.

4. Thread the Strap

1. Hold the watch face-up.
2. Insert the long end of the strap downward through the top spring bar (12 o’clock side).
3. Pull it all the way through.
4. Thread it upward through the bottom spring bar (6 o’clock side).
5. The strap should now run flat across the back of the watch case.

5. Secure the Keeper

Most NATO straps have a secondary short strap with an extra keeper loop.

• Pass the long strap end through the keeper.
• Adjust so the watch head sits between the two sets of keepers.
• This prevents the watch from sliding and keeps it centered.

👉 Note: Some straps include a “tongue” keeper—always ensure the strap is threaded cleanly under it for proper fit.

6. Adjust and Wear

• Place the watch on your wrist.
• Insert the free end through the buckle and secure it.
• Tuck the remaining strap length back into the keepers.
• For a military-inspired look, fold the extra strap back and tuck it under for a snug, clean finish.

Why NATO Straps Are a Must-Have

• Security: Even if one spring bar fails, the watch stays attached.
• Durability: Heavy-duty nylon resists fraying, sweat, and water.
• Versatility: Countless colours and patterns to suit any style.
• Convenience: Swap straps in minutes—no tools required once spring bars are installed.
