Measuring your strap
Two measurements are enough: your watch’s lug width and your wrist size.
Lug width
- Remove the current strap or measure flush with the case.
- Measure the inside gap between the two lugs with a ruler or calipers.
- Round to the nearest millimetre. The most common widths run from 18 to 22 mm.
Length for your wrist
| Wrist size | Long side | Short side |
|---|---|---|
| 14 – 15,5 cm | 105 mm | 65 mm |
| 15,5 – 17 cm | 115 mm | 70 mm |
| 17 – 18,5 cm | 120 mm | 75 mm |
| 18,5 – 20 cm | 125 mm | 80 mm |
| 20 – 21,5 cm | 130 mm | 85 mm |
Indicative values for a 38 to 42 mm case. For a large case, take 5 mm off the long side.
