Size guide
Match the case to the wrist, then pair the strap width to the case. Print a paper watch if you want to try the size before you buy.

How to measure
How do I know if it will fit?
Use a flexible measuring tape, or wrap a phone charger cord around your wrist just above the wrist bone and measure it against a straight ruler. Note the circumference, then match it to the strap family below — mesh straps have more range than leather or Perlon.
| Dial size — strap | Wrist (cm) | Wrist (in) |
|---|---|---|
| 40 mm Leather / Perlon | 13–18 cm | 5.1–7" |
| 40 mm Mesh | 13.5–22 cm | 5.3–8.6" |
| 38 mm Mesh | 12–18 cm | 4.7–7" |
| 32 mm Leather / Perlon | 13–17.5 cm | 5.1–6.8" |
| 32 mm Mesh | 13–21.5 cm | 5.1–8.4" |
| 30 mm Leather / Perlon | 12–16 cm | 4.7–6.2" |
| 30 mm Mesh | 13–21.5 cm | 5.1–8.4" |
| 26 mm Leather | 12.5–17.5 cm | 4.9–6.9" |
| 26 mm Mesh | 14–19 cm | 5.5–7.5" |
