Wrist circumference

Wrist circumference of about 11 to 18 cm
The WobL watch is suitable for wrist circumference of about 11 to 18 cm.
The WobL + watch is suitable for wrist circumference of about 10 to 19 cm.

Depending on the body of the child, the watch is suitable for children from 4 years and up.

With a wrist circumference of 9 centimeters or smaller, the watch will be very loose, and it may be less effective (the vibrating alarm will still draw the attention of the child).

Above 18 cm the strap of the traditional WobL watch is too tight. The WobL + watch fits perfectly around a wrist with a circumference of 19 cm.
