Sizing Guide
Three measurements. Five minutes. A strap that fits perfectly the first time.
Measurement 01
Lug Width
The most important measurement. Lug width is the distance between the two lugs — the protruding arms at the top and bottom of your watch case where the strap attaches.
Use a digital calliper or a ruler with millimetre markings. Measure at the point where the spring bar passes through — this is typically at the inner edge of the lugs, not the outer tip. If you are between sizes, size down.
We make: 16 · 17 · 18 · 19 · 20 · 21 · 22 · 24mm
Measure at the spring bar, inner lug edge
Measurement 02
Strap Length
A watch strap has two ends. The long end passes through the buckle and carries the holes. The short end holds the buckle.
| Size | Long End | Short End | Wrist |
|---|---|---|---|
| Short | 110mm | 65mm | Under 155mm |
| Regular | 120mm | 75mm | 155 – 190mm |
| Long | 130mm | 85mm | 190mm+ |
To measure your wrist, wrap a tailor’s tape or a strip of paper around your wrist just below the wrist bone. Where the end meets the strip — that is your wrist circumference. Most adults fall in the Regular range.
Measurement 03
Taper & Buckle Width
Most straps taper from the lug width to a narrower buckle end. A 20mm strap, for example, typically tapers to 18mm at the buckle. This is denoted as 20/18.
Our standard tapers are listed on each product page. If you have an existing buckle you want to reuse, measure its inner pin width — that is the buckle width you need. Custom tapers are available on request.
| Lug Width | Standard Taper |
|---|---|
| 18mm | 18/16 |
| 19mm | 19/16 |
| 20mm | 20/18 |
| 22mm | 22/20 |
| 24mm | 24/22 |

After you know the size
Choose the strap personality
Once you know your lug width, length, and taper, the next choice is personality. Pick the material and style that changes the way your watch feels on the wrist.

Texture and natural character
Choose Ostrich Leg when you want a distinctive textured strap that adds depth to vintage watches, dress watches, and simple dials.
Motorsport and chronograph style
Choose GTS Rally when you want perforated leather, vintage racing energy, and a sportier feel for a chronograph or casual watch.
Casual comfort and pull-up character
Choose the LE Series when you want pull-up goatskin that feels relaxed, lightweight, and more lived-in as it wears.
