How to Change a Watch Strap: Step-by-Step Guide

A new watch strap can give your watch a completely new look and feel. This guide explains what lug width is, how to change a watch strap yourself and which tools you need.

What is lug width?

Lug width is the distance between the lugs of the watch case, where the strap is attached. It is measured in millimetres and is the single most important measurement when you choose a new watch strap or watch band.

Common sizes are 18mm, 20mm, 22mm and 24mm, but other sizes exist too. Measure the lug width carefully to make sure your new strap fits perfectly.

How to change a watch strap

Changing a watch strap is a fairly simple job that you can do at home with the right tools. Follow these steps:

1. Prepare your tools: You need a spring bar tool, plus new spring bars if the old ones are worn or damaged.
2. Remove the old strap: Use the spring bar tool to compress the spring bars that hold the strap to the watch. Work carefully so you don't scratch the case.
3. Fit the new strap: Insert the spring bars into the new strap. Seat one end of the spring bar in the lug hole, then use the tool to compress the other end while you slide it into place. Give the strap a gentle tug to check that it is secure.

Tip: straps with quick release spring bars can be swapped by hand, without any tools at all.

Tools you need

To change a watch strap you only need a few basic tools:

• Spring bar tool: Makes it easy to remove and fit spring bars. Its small fork fits neatly around the spring bar.
• Spring bars: These small metal pins hold the strap in place. It's worth keeping a few spare spring bars in case the old ones break or get lost.
• Soft cloth: Lay the watch on a soft cloth to protect it from scratches while you work.
