Check out the $99 (retail MSRP) http://www.wime.tw NanoPhone that can be used as the NanoWatch wrist watch. It connects to your Smartphone using Bluetooth and it can also use its own built-in GPRS SIM card modem. The Wime NanoWatch does not run Android, but its embedded Linux OS synchronizes with Android: "Smart advisor that will remind you the new SMS, miss call, Gmail of your android smart phone". They gave me a review sample, I'll try to post a video review in the days/weeks to come. I'll try to figure out exactly what kind of features work yet in sychronization with my Bluetooth Android devices. Let me know in the comments what I should try to test on it.
