Hi, the sports wristband is included in the two available sizes when you buy it. You can therefore try out whether the size S/M (130-180mm circumference) or M/L (150-200mm) fits better.
Hello, the sports wristband is a plastic wristband. The length of one side is approx. 13.5 cm, the other approx. 9 cm. The narrowest hole (circumference) including the watch is approx. 18 cm, the widest approx. 22.5 cm. It is usually the bracelet that is on display in the showrooms.
