A timely.. cough.. thread.
I just got in a WIMM One watch module from
WIMM Labs:

It's running Android 2.1 (soon should be 2.3) and has a multitouch screen, GPS, WiFi and Bluetooth.
It has an eclipse SDK add-on and I've already written a test microapp of my own for it. You can even create your own watchface apps; it has Java libraries for that. Love being able to roll my own stuff!
So far, I've got it set up with world weather, map and time apps, Google calendar sync, an amazingly usable news reader app, a tilt ball puzzle game. The built-in tools like alarms and timers are easy to use. It also comes with a variety of watchfaces, analog/digital and some with your next calendar event showing. And yes, someone on their forum even posted a geeky old style calculator app with tiny buttons
Of course, it will also show incoming caller id and texts from your phone if you wish. Speaker, but no microphone, however might be able to use a Bluetooth headset for voice input. Not sure yet.

In another month, Italy based
I'm Watch should be shipping their Android 1.6 based watch, which they claim is the first with a curved capacitive screen. As befits a stylish country of origin, it's available in materials from inexpensive plastic to $10K diamonds:

No GPS or WiFI on it, but it does have a microphone so there's hope for eventually getting an Android upgrade and voice control.
Smart watches are definitely heating up. I can easily see Apple jumping into this market.
