Strap Length Size Guide
This size guide is an approximation only as fit depends on factors such as your watch case lug-to-lug and thickness measurements and how loose/snug one prefers to wear a watch. We recommend checking the length of your existing strap for comparison.
Deployant clasps: this size guide is not applicable.
Canvas and bund straps: add 0.25” (0.6 cm) to your wrist circumference measurement and opt for a longer-than-usual strap length.
