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 Extent in black with red stitching has a racy feel, perfect for picking out red details on a dial.

It's a smooth silicone strap with a stitched edge, so at a glance it passes for leather, yet it shrugs off water and sweat and wipes clean in seconds. The contrast stitching runs all the way round and is what gives it its character. It narrows by 2mm towards the buckle for a neat finish on the wrist.

It comes with spring bars as standard. Available in three colourways, from 18mm to 24mm.

A quality well made silicone watch strap

A quality well made watch strap to replace a leather strap supplied by a high street shoe repair franchise that lasted less than a year .
My work watch takes a battering and leather straps or metal bracelets get punished.
This one feels like it could last the distance.
