Measure first. Wear with confidence.

Your watch.The right width.

A strap must match your watch's lug width exactly. Here's how to measure it — and what else determines a good fit.

01 · Lug width

What lug width means

Lug width is the inside distance between the lugs — the projections at the top and bottom of the case that hold the spring bar. It is measured in millimetres and must match the strap’s width at the watch end.

Common widths are 18, 20 and 22 mm; smaller watches often use 12–16 mm, and odd sizes such as 19 or 21 mm exist on some dress and vintage watches. Our straps come in 18, 20 and 22 mm.

02 · How to measure

Five careful steps

Calipers give the most reliable reading. A good millimetre ruler works if you are careful. You can also check the manufacturer’s specification for your exact model reference.

  1. 1Take off the watch and look at where the strap meets the case.
  2. 2Measure the inside distance between the lugs in millimetres, ideally with calipers.
  3. 3Check the existing strap's width at the watch end, and how it attaches.
  4. 4Select the same width on the product page and review strap length for your wrist.
  5. 5If the case has a curved, integrated, screw-in or proprietary attachment, ask before ordering.

03 · Width vs length

Strap width, buckle width and length

Strap width is measured at the lug end and must match your lug width. Most straps taper towards the buckle — so the buckle width is usually narrower. Ours taper by 2 mm — a 20 mm strap narrows to an 18 mm buckle.

Length is given as two numbers: the long piece (with holes) and the buckle piece. Our reference length is about 115 / 75 mm, to be confirmed on finished samples.

Wrist circumference: wrap a soft tape (or a strip of paper you then measure) around the wrist where you wear your watch. Snug, not tight.

04 · Spring bars

Standard and quick-release

Most traditional watches hold the strap with spring bars: spring-loaded pins whose tips sit in small holes inside the lugs. Standard bars are compressed with a spring-bar tool; quick-release bars have a small lever so they can be changed by hand.

Work over a soft surface, and if your watch is valuable, consider asking a watchmaker to fit the strap.

05 · Compatibility

Why some watches need proprietary straps

Lug width alone does not guarantee fit. Some watches are designed around their own straps or bracelets:

  • integrated bracelets that flow directly from the case;
  • proprietary connectors, screw-in bars or unusual lug shapes;
  • cases with curved end links or very tight lug-to-case gaps.

Our straps are independent aftermarket straps for standard spring-bar lugs. We don’t claim compatibility by brand or model name — please check your watch, and ask us if unsure. Not for smartwatches.
