Luxury watches were the sort of thing you could wind up and pass down to family members through the ages. However, a new type of watch called a "smart watch" is starting to look like regular watches. That big Android Wear update isn't just about allowing cellular data on smartwatches, it’s a computerized wristwatch with functionality that is more than just timekeeping. Some smart watches may include features such as a camera, heart rate monitor, and fitness tracker. Like other computers, a smart watch may control or retrieve data from other instruments and/or computers. They may also support Bluetooth, Wi-Fi, and GPS. Smart watches are becoming more popular in recent years due to their easy to use interfaces and health-related applications.
