Size guide
Case size
Measure your wrist just below the bone. As a guide: under 16cm → 30–36mm; 16–18cm → 36–41mm; over 18cm → 40–44mm. Lug-to-lug length matters more than diameter — every product page lists it under Details.
Strap length
| Size | Wrist |
|---|---|
| S | 150–175mm |
| M | 165–195mm |
| L | 185–215mm |
Bracelets and mesh straps are one size and adjust with removable links or a sliding clasp.
