How to find the correct size watch strap

Measuring your watch strap is a straightforward yet crucial step in finding a new strap that fits both your watch case and wrist comfortably.

If you’ve currently got a leather watch strap, the quickest and easiest way to determine width is simply to look at the back side of the strap. Some – not all – have the width imprinted onto the leather. For example, if there’s a ‘22’ on the back of your leather strap, it means the width is 22mm.

Simple!

If your strap doesn’t have a number on it – or you’re dealing with a strap made from a different material – you’ll need to measure the width yourself. But this isn’t difficult. What you need to do is find the ‘lug width’, which is the size of the gap between the lugs (or horns). The lugs are the two metal parts on each side of the watch case that protrude out and connect the case to the strap. Measure between the inside of the lugs on one side, and record your measurement in millimetres.

The image above shows how to measure the lug width. On this watch it measures 20mm so requires a 20mm watch strap. Always measure accurately and in millimeters, if your rulers is in centimeters you can always convert this to millimeters (we don't advise measuring in inches).

The Submerge ISO Dive in black is a tough, no-fuss strap that suits almost any dive or sports watch.

It's a soft, flexible silicone strap with a row of rectangular cut-outs running along its length, which gives it a bold, technical look and keeps it light on the wrist. Silicone is happy getting wet, so it's a natural fit for swimming, the beach or a day on the water, and it rinses clean in seconds. It barely narrows, if at all, towards the buckle, so it keeps a chunky, sporty profile all the way down.

It comes with spring bars as standard and a square steel buckle. Available in six colours, from 18mm to 26mm.

What the measurements mean
  • Width: fits between your watch's lugs, so match it to your lug width (a on the diagram).
  • Length: both pieces added together. In brackets, the first figure is the buckle end (c) and the second is the hole end (d).
  • Buckle width: from 20mm up the strap doesn't narrow, so it's the same width at the buckle. The 18mm narrows very slightly, to 17mm (b).
