If you like your current watch but wish it were just a bit smarter, you can transform it into a smartwatch with the Kairos T-Band.

The T-Band comes in three different models each with its own set of tech, depending on what you want your watch to be able to do.

The T-Band ND is the basic model that allows you to set up your watch to vibrate and flash an LED indicator when you get a text message or social media notification. It also has a health-tracking GSR sensor. The T-Band ND can go seven days on a full charge.

The T-Band HD has all the same functions as the ND, but with a digital display. If an eye-catching digital display is not your thing, the T-Band HD’s digital display blends into the band when not in use. This watch will pull three days on a full charge.

The T-Band OD has all the same features but with a full-color OLED, anti-scratch-coated display with touchscreen capabilities. You can also text from you watch using the integrated voice-to-text microphone. Obviously, this one is not going to hold a charge as long as the other models.

The Kairos T-Band is available for pre-order through an Indiegogo campaign. Prices start at $129. They are scheduled to being delivery by April of 2015.
