There are some Bluetooth enabled watches like the Sony Ericsson MBW-150.
They're able to show and manage incoming calls, SMSes, emails, notifications and control your media player.
Originally they were intended to work with Sony Ericsson mobile phones only, but soon apps for other platforms were developed.
There is an app for maemo 5, called OpenWatch.
Basicall it's a packaged python script.
Check out the package details on maemo.org: http://maemo.org/packages/source/vie...watch/0.4.1-1/
I'm offering a brand new Sony Ericsson MBW-150 Music Edition (http://www.sonyericsson.com/cws/prod...on?lc=de&cc=ch) to the first developer who agrees to fully develop an app like OpenWatch for MeeGo Harmattan.

The app has to enable the watch to:
- show all notifications
- show incoming calls
- mute/reject calls
- show incoming SMSes
- show incoming emails
- control the media-player
- show titles of the played media
- show battery state of the N950/N9
- show clock from N950/N9
- show date from N950/N9
- anything you want to add

Best regards and happy coding,
Cosimo
