A German regulator has banned the sale of smartwatches aimed at children, describing them as spying devices.
It had previously banned an internet-connected doll called, My Friend Cayla, for similar reasons.
Telecoms regulator the Federal Network Agency urged parents who had such watches to destroy them.
One expert said the decision could be a "game-changer" for internet-connected devices.
"Poorly secured smart devices often allow for privacy invasion. That is really concerning when it comes to kids' GPS tracking watches - the very watches that are supposed to help keep them safe," said Ken Munro, a security expert at Pen Test Partners.
