18mm Leather Watch Straps – Complete Guide

18mm is one of the most common lug widths, but it covers a different kind of watch than 20 or 22mm – here's what to bear in mind if your watch has that width.

Which watches have an 18mm lug width?

18mm is most often found on watches with a diameter of around 34–38mm: classic dress watches, slimmer men's watches and many ladies' watches. If you're not sure your watch really is 18mm, measure the distance between the lugs following our guide to measuring your watch strap size before you order – a watch that looks "medium-sized" can still have an 18mm lug width.

Our 18mm range

We offer 18mm in several styles and materials: classic smooth leather watch straps in brown, dark brown, red, green and black with contrast stitching, vintage calfskin watch straps for a more rugged feel, suede watch straps in six colours, and leather Nato straps if you'd rather have a strap that wraps around the whole case. All are also available in 20 and 22mm in case you change watches later.

Buying tips

Because 18mm straps usually sit on slimmer cases, think about how chunky a buckle you want – an oversized buckle can look out of proportion on a small watch. Our buckles come in both black and gold-tone; see watch strap buckles if you'd like to change that too.

Conclusion

18mm is the standard width for classic and smaller watch cases, and we cover it across practically our entire range. Filter by 18mm under leather watch straps to see everything at once.
