Strap Length Sizing Guide
Every strap has two halves — the long end (with the holes) and the short end (with the buckle). Our sizes are listed as short/long in millimeters.
Our sizes
| Size | Short End | Long End | Fits Wrist |
|---|---|---|---|
| S | 75mm | 115mm | 5.5"–6.75" |
| M* | 80mm | 125mm | 6.5"–7.75" |
| L | 85mm | 135mm | 7.5"–8.5" |
*Medium fits most wrist sizes. Sizes overlap intentionally — if you're between sizes, either will work. Size up for a looser fit, down for a snugger fit.
How to measure your wrist
Wrap a flexible tape measure or a strip of paper snugly around your wrist where you wear your watch. Don't pull it tight — you want a comfortable fit, not a compression.
If using paper or string, mark where it overlaps, lay it flat, and measure with a ruler.
Need an exact fit?
If your wrist falls outside our S/M/L range, or you want a precision fit, select "Other" on the product page and choose your exact wrist size. We'll cut your strap to match.
Wrist sizes of 8.5" and above carry a $20 upcharge for additional leather.
Compare to a strap you own
If you have a strap that fits well, measure each half separately — don't include the buckle hardware. Compare those numbers to our sizing chart above.
