Not nearly as easy to hack as this Bluetooth with OLED, but still a watch designed by a single guy located in Tempe. I bought one from ThinkGeek a while back version 1 (pictured on his website, the picture on ThinkGeek is version 2) and I love it. It is unique and I always get looks from people.

It uses an MSP430 at its core.
