If you have not owned a smart watch before, here is some information about how smart watches work.
The majority of modern-day watches have some kind of smart watch functionality, including Wi-Fi, Bluetooth, GPS technology and health tracking capabilities.
Your smart watch will connect to your smartphone and allows you to monitor, track and record any activity you are involved in. In many cases, you can actually view, send and answer messages, calls and alerts you receive on your mobile phone when connected.
Some smart watches even support a separate slot for a SIM card which turns it into an independent device giving you cellphone capabilities, without needing your cellphone with you.
