The ideal first watch for children age 4+. The clear face design and
simple teaching method make it really easy for children to learn to tell
the time. Worn every day, your child will be able to practice their new
skill wherever they go. These watches have a 33 mm diameter case. They
are water resistant and can withstand splashing, but not total
immersion. The washable nylon strap fits wrists from 12 cm to 18 cm
(child to adult).
