Smart watches designed for children are enjoying a spike in popularity in China.

Shenzhen Continental Wireless Co Ltd, known for its Abardeen smart watch brand, submitted an application last Saturday to be listed on the National Equities Exchange and Quotations, better known as the New Third Board, to fund further development of its devices.

Created in 2008 as a laptop and tablet manufacturer, Continental Wireless shifted its focus to wearables in 2013.
