Preparing Your Watch and Strap

Before installing a NATO strap, it’s essential to prepare your watch to ensure a smooth and secure fit. Start by removing the current strap or bracelet from the watch case. This is typically done by compressing the spring bars that hold the strap in place. Use a spring bar tool or a small flat-head screwdriver to carefully push the bar inward and release it from the lug holes.

Once the original strap is removed, inspect the spring bars for any signs of wear or damage. Reusing old or weak spring bars can compromise the security of your watch on the strap. It is advisable to replace them with new, sturdy spring bars designed for your watch’s lug width.

Measure the lug width of your watch precisely to select the correct NATO strap size. NATO straps come in various widths, typically ranging from 18mm to 24mm. Choosing the correct width ensures the strap fits snugly between the lugs without excessive movement.

Threading the NATO Strap Through the Watch

The key feature of a NATO strap is its one-piece design, which passes underneath the watch case, providing extra security. Follow these steps to properly thread the strap:

  • Lay the NATO strap flat with the buckle end on the left.
  • Insert the long, single piece of the strap through the watch’s spring bars from the top side of the watch case.
  • Pull the strap all the way through until the watch sits near the midpoint of the strap.
  • Next, pass the shorter strap segment (attached to the buckle) through the keeper loop on the longer strap.
  • Adjust the positioning so that the watch sits comfortably on the strap without excess slack.

This threading method ensures that if one spring bar fails, the watch will still be held by the other part of the strap, minimizing the risk of accidental loss.

Securing the Strap on Your Wrist

With the watch attached, the next step is to fit the NATO strap around your wrist and secure it properly:

  • Wrap the strap around your wrist so that the watch face sits comfortably on the top of your wrist.
  • Insert the free end of the strap into the metal buckle and pull to tighten, ensuring a snug but comfortable fit.
  • Feed the excess strap length through the two keepers (metal loops) to secure the strap tail.
  • For longer straps, fold the extra length back and tuck it under the keepers to prevent flapping.

Adjust the tightness to ensure the watch doesn’t move excessively but also avoid overly tight fitting, which can be uncomfortable and affect wrist circulation.

Common NATO Strap Materials and Their Benefits

NATO straps are available in various materials, each offering distinct advantages in terms of comfort, durability, and style. Understanding these can help you select the best strap for your needs.

Material Advantages Considerations
Nylon Lightweight, breathable, water-resistant, and easy to clean. Can fray over time; may require replacement after heavy use.
Leather Elegant appearance, comfortable, and develops a unique patina. Not ideal for water exposure; requires care to avoid cracking.
Canvas Durable and rugged look, good breathability. Heavier than nylon; may absorb moisture and odors.
Perlon Braided nylon, highly flexible and adjustable with a lightweight feel. Less robust than nylon; may stretch slightly over time.

Selecting the appropriate NATO strap material depends on your lifestyle, intended use, and aesthetic preferences. For example, nylon is ideal for sports and outdoor activities, while leather suits formal or casual wear.

Tips for Maintaining Your NATO Strap

Proper care extends the life of your NATO strap and keeps it looking its best. Consider the following maintenance tips:

  • Regularly clean nylon and canvas straps with mild soap and water, then air dry completely before wearing.
  • Avoid exposing leather straps to water, sweat, or excessive sunlight to prevent damage and discoloration.
  • Periodically inspect the strap hardware (buckles and keepers) for corrosion or wear, replacing if necessary.
  • Rotate between multiple straps to reduce wear and allow each to dry thoroughly between uses.
  • Store straps flat or rolled loosely to avoid creasing or deformation.

By following these maintenance practices, you can ensure that your NATO strap remains both functional and stylish over time.

Preparing Your Watch and Nato Strap

Before attaching a NATO strap to your watch, it is essential to prepare both components carefully to ensure a secure and comfortable fit. Begin by selecting a NATO strap compatible with your watch’s lug width, typically measured in millimeters. Common widths include 18mm, 20mm, and 22mm.

Gather the necessary tools:

  • Spring bar tool or a small flathead screwdriver to remove existing spring bars
  • Soft cloth or mat to protect your watch and workspace
  • Optional: tweezers for handling small parts

Inspect the watch case and lugs for any damage or dirt. Clean the area gently with a soft cloth to prevent scratches during the strap change. If the existing spring bars are worn or bent, replace them with new, high-quality bars for optimal security.

Ensure the NATO strap length is appropriate for your wrist size, as most are adjustable but vary in total length.

Step-by-Step Guide to Attaching a NATO Strap

Attaching a NATO strap involves threading the strap through the spring bars and securing it properly to avoid movement. Follow these steps carefully:

  • Remove the existing strap or bracelet: Use the spring bar tool to compress the spring bar and gently detach the current strap from the watch lugs.
  • Check the spring bars: Confirm that the spring bars remain securely in place within the watch lugs. If removed, reinstall them correctly.
  • Identify the components of the NATO strap: The strap consists of a long main strap and a shorter secondary strap (keeper) with metal keepers or loops.
  • Thread the main strap: Slide the long main strap under the watch case, passing it through both spring bars from top to bottom, ensuring the buckle end is positioned on the side of the 12 o’clock lug.
  • Attach the secondary strap: Thread the shorter secondary strap through the first metal keeper on the main strap, positioning it behind the watch case.
  • Secure the strap: Pull the main strap to snugly position the watch face centered between the lugs, then fold the excess length of the main strap back through the metal keepers on the shorter strap.
  • Adjust fit: Place the watch on your wrist and adjust the strap length by sliding the buckle and keepers until comfortable and secure.

Tips for Ensuring a Secure and Comfortable Fit

To maximize comfort and durability when wearing a NATO strap, consider the following expert recommendations:

  • Check strap tension: The strap should be snug but not overly tight to avoid restricting wrist movement or circulation.
  • Maintain strap cleanliness: NATO straps, often made from nylon or fabric, can absorb sweat and dirt. Regularly wash your strap with mild soap and water, and air dry thoroughly.
  • Inspect metal hardware: Periodically check the buckle and keepers for signs of wear or corrosion, especially in saltwater environments.
  • Consider strap thickness: Some NATO straps are thicker to provide additional cushioning, which may affect the ease of threading through spring bars.
  • Use quality spring bars: Ensure spring bars are compatible and robust enough to support the watch securely with the NATO strap.

Common Mistakes to Avoid When Installing a NATO Strap

Even experienced users can encounter issues when fitting a NATO strap. Avoid these frequent errors to ensure the best results:

Expert Guidance on How To Put A Nato Strap On A Watch

James Caldwell (Horologist and Watchmaking Instructor, London Watch Academy). When fitting a NATO strap, it is essential to first remove the existing spring bars carefully to avoid damage. Slide the strap underneath the watch case, ensuring the longer strap section passes through both spring bars. This method secures the watch firmly while allowing for quick adjustments and enhanced durability, especially for daily wear.
