Here is a watch band that turns any watch into a smartwatch. It features multi-colour LED, vibration alerts and gesture recognition, so you can reject calls, avoid losing your phone, and track your activity. The watch band can track your distance, calories burned, and steps. You can also reject a call with one tap.
Unique also has a programmable NFC tag that allows you to upload business card and other information. If you are not ready to get rid of your old watch for a new smartwatch, you may want to get this watch band instead.
