Watch straps by lug width, material, and style

A watch lug is the point where the strap attaches to the watch case. The lug size (also called lug width) is the distance between the two lugs, measured in millimetres.
To find yours, use a ruler with a millimetre scale and measure the inside gap between the lugs.
Alternatively, measure the width of your current strap where it meets the case, the size is sometimes printed on the underside of the strap. Once you know it, filter by lug width on our website to see every strap that fits.

Not all watch straps are universal. A standard strap can fit many watches with straight lugs when its width matches the lug width of the watch. Measure the inside gap between the lugs before ordering. Watches with proprietary adapters, curved or integrated attachments, and some smartwatch cases need a model-specific strap or adapter. For a smartwatch, also check the compatibility list on the product page.

Head to our dedicated smartwatch straps category, shop by brand, and filter by your exact model. You can also check the compatibility list at the bottom of each product page to confirm the strap fits your device.

A quick-release strap (also called easy-change, quick-change, or easy-install) has integrated spring bars with a small lever. It lets you swap straps in seconds, by hand, with no tools required.

The key question is whether a strap will fit your current watch. Here’s how to work it out in a minute.

1. Check that your current strap has a straight end.
Then measure its width at the point where it attaches to the case. If you no longer have the old strap, measure the gap between the watch’s lugs instead, that’s the lug width.

You’ll find each strap’s size in several places:

• in the product name;
• below each product image;
• in the technical specifications.

2. Want to keep your original buckle? If so, check the buckle size in the technical specifications, along with the shape of the buckle tongue and the position of the strap holes.

Once you know your size, filter by width on our website. The main filters sit at the top of every category, and our advanced filter lets you narrow down further by material, colour and more.
