The SmartBandTalk is equipped with an E-paper display, which makes it easy to read by daylight and ensures it is not so bright that it will disturb you at night. The case is available in black or white and can be changed within seconds without requiring any tools. SmartWatch 3 not only has a finely textured exterior, but offers users a colour choice between black, white, pink or lime and also comes in metal or leather to suit the wearer’s taste.
