• Specification - Watch band is 1.4mm thick and 280mm long in both 20mm & 22mm width. We recommend a wrist size of 16cm (6.25 inches) to 24.5cm (9.5 inches) for this strap but watch geometry can sometimes be a contributing factor in the maximum and minimum length. In the unlikely event your watch strap does not fit, please return it for a full refund.
