The Pebble is a watch unlike any other, which is why it managed to get over $10 million in backing on Kickstarter. This fully customizable smart watch uses an e-ink display, similar to the kind seen in e-book readers. While the Pebble primarily functions as a watch, it also connects to your Android device or iPhone using Bluetooth.
Pebble is the last watch you'll ever need, as the watch face is customizable and Pebble runs useful apps through your phone. It also displays notifications for caller ID, emails, text messages, and more.
