How To Replace A Watch Buckle

If you’ve ever wanted to give your timepiece a fresh look or replace worn-out hardware, learning how to remove a watch buckle is an essential watch maintenance skill. Whether you’re swapping out a standard tang buckle for a deployant clasp or upgrading to match your watch band finish, it’s a simple process you can do at home with the right tools.

To replace or change the buckle on your watch strap, you’ll need a spring bar removal tool and a new buckle that fits your band correctly.

Measuring for the Right Buckle:

Before you begin, measure the width of your watch strap at the buckle end to know what size buckle you need.

For example, if your watch band measures 20mm at the buckle end, you’ll need a 20mm buckle.

Keep in mind that the buckle width is often different from the width at the watch head, as many straps taper toward the buckle end.

You should also check the thorn width (the small tongue that fits into the strap holes). A heavy-duty pre-V buckle may not fit a strap that originally had a thinner tang buckle because the cutout for the thorn may be too small.

Now that you know how to choose the right fit, let’s get started.

STEP 1 – Removing the Old Buckle

Now that you know what to look for, let’s walk through how to remove a watch buckle safely.

Use the forked end of your spring bar removal tool to compress the spring bar securing the buckle to the watch strap. Insert the tool between the strap and the edge of the buckle so that the forked end hugs the spring bar. Push inward toward the strap to release the spring bar from the buckle.

Tip: Some buckles feature small drilled holes on the sides to make this process easier. If yours does, use the pin pusher end of the tool and press into the hole to release the spring bar. This provides more control and reduces the risk of scratching your watch band.

Next, pull the spring bar out completely. If it’s tight, gently push it out with the pin end of your tool. Once the spring bar is removed, the buckle’s thorn (the metal tongue) will come free or can easily be lifted out by hand.

Your old watch buckle is now fully removed and ready to be replaced.

STEP 2 – Installing the New Buckle

Now that you’ve mastered how to change a watch buckle, it’s time to install your new one.

Insert the spring bar through one side of the watch strap until it reaches the cutout.

Next, place the thorn into the cutout and hold it in place while you push the spring bar through the rest of the way. Use the pin pusher if you need help guiding it.

Attach the buckle by catching one side of it onto the spring bar.

Use the forked end of the tool to compress the other side of the spring bar and slide the buckle into place until you feel it click securely.

Give the watch band a gentle tug to ensure everything is secure and the new buckle is properly installed.

Common Questions

Can You Change the Buckle on a Watch Strap?

Yes — you can change the buckle on a watch strap as long as the new buckle matches the correct size at the strap’s buckle end. Most watch bands, especially leather, silicone, and nylon styles, use removable buckles that can easily be swapped with a spring bar tool.

If your watch strap tapers, be sure to measure the buckle end specifically before purchasing a new buckle.

Final Tips

Always measure your watch strap at the buckle end for the correct size.

Work slowly on a soft surface to avoid scratches on your watch or watch band.

Consider upgrading to a deployant clasp for added comfort and a cleaner, dressier look.

Replacing or removing a watch buckle is a quick and rewarding way to refresh your favorite timepiece — no jeweler required.
