With the development of mobile technology, many traditional electronic products also began to add mobile functions. For example, in the past, they can only use watches to see time. Now they can also be connected to the Internet through smart phones or home networks to display incoming call information, twitter and news feeds, weather information and other contents.

The new watches can be called smart watches. Some are on sale and some are still in the sample test stage. Such products are mainly designed for consumers to use when it is inconvenient to use smart phones, such as when they are riding a bike or when their hands are full of things.
