From 7 to 10 years: Independent outdoor play It's generally recommended that children only get a smartwatch when they can play outside independently. Therefore, it's not easy to specify the exact age at which a child can wear a smartwatch. However, somewhere between 7 and 10 years old, a child is old enough to use a children's smartwatch. The Ice-Watch Junior smartwatches, for example, are aimed at this age group with cheerful colors, customizable screens, and games. From 11 to 14 years: Smartwatch with a call function Older children and pre-teens are already very digitally savvy and can easily use a smartwatch independently. However, it's recommended that children under 14 not get a smartphone or smartwatch with full connectivity due to the risks of internet use. In this case, a simple activity tracker or a smartwatch with a call function (and a limited number of pre-programmed contacts) is a good transition model between a children's smartwatch and a fully adult-sized smartwatch. For example, Calypso Kids has affordable activity trackers in its range for sporty kids and both Ice Watch and Garmin offer full-fledged smartwatches with calling functions for children.
