Jiangsu Tbit Technology Co and China Mobile Jiangsu branch jointly released a child-oriented smart watch at the fifth China International Internet of Things (Sensor Network) Expo in the city of Wuxi, Jiangsu province.

The watch is the first wearable device designed for children aged 4 to 12 in the country. It adopts antibacterial material and combines the functions of conversation, real-time positioning and position recording. It can also send information about when children leave home and arrive at and leave school to parents' mobile phones.

The current price of the watch is 360 yuan ($59), with one year of free service. The service charges only 5 yuan per month from the second year.

Jiangsu Tbit Technology Co, headquartered in Shenzhen, Guangdong province, is a leading company in positioning technology R&D and product manufacturing. It settled in Binhu district of Wuxi early this year with a registered capital of 20 million yuan. The company also founded an assembly factory in the district and cooperated with China Mobile and Yadea Technology Group to build a smart electric vehicle research center, which is expected to reach an output value of 150 million yuan in 2014.
