How to Change a Watch Band (4 Easy Steps)

Swapping a strap is the fastest way to change a watch’s personality. You need a spring bar tool, a soft cloth, and a strap that matches your lug width. Four steps. No shop visit.

What you need

• A double-ended spring bar tool: https://www.amazon.com/dp/B0129CJNUY
• A new strap sized to your lug width (often 18, 20, or 22 mm)
• A soft cloth to protect the case

Confirm whether your watch uses spring bars or screw-in bars before you start. This guide is for spring-bar straps.

Step 1 — Confirm lug width and strap type

Measure the inner distance between the lugs (where the strap sits). Match that millimeter width on the new strap. If the old strap uses screws instead of spring bars, stop — you need the correct screwdriver, not a spring bar fork.

Step 2 — Remove the old strap

Lay the watch face-up on a soft cloth. Insert the forked end of the spring bar tool into the lug gap, compress the spring bar, and ease that end out of the lug. Repeat on the other side. Keep the bars; you may reuse them if they are undamaged.

Step 3 — Install the new strap

Seat one spring bar fully into the new strap end. Compress and guide one tip into a lug hole, then the other tip into the opposite hole until it clicks home. Repeat for the second strap end. Tug gently on each side to confirm both bars are fully seated.

Step 4 — Check fit and finish

Wear the watch and confirm the strap is secure and comfortable. Wipe the case. If a bar feels soft or walks out, reseat it or replace the bar before wearing it out.

Tips

• Work slowly — scratched lugs are permanent.
• Do not use paperclips or knives as improvised tools.
• NATO/nylon/Zulu straps are a style category available from third parties; they are not listed here as Wrist & Style in-stock products.

FAQs

Can I change a watch band at home?

Yes, for most spring-bar watches, with a proper spring bar tool and patience.

Can I do it without tools?

Not safely. Improvised tools chew lug holes and bend bars.

How do I know the strap size?

Measure lug width in millimeters between the inner faces of the lugs.

Soft close

Once the band is on, park the tool where you can find it. The W&S spring bar tool is on Amazon at the link above.
