With the development of mobile technology, many traditional electronic products have begun to add mobile functions, such as watches, which used to be used to tell time. Now, they can also connect to the Internet through smart phones or home networks to display incoming calls, Twitter and news subscriptions, weather information and other content.

This new type of watches can be called smart watches, some of which are already on the market, and some are still in the sample testing stage. This product is mainly designed for consumers to use smart phones at inconvenient times, such as riding bicycles or holding things in their hands.
