Sony Ericsson tends to be serious about Bluetooth and has never been satisfied with producing a simple line of wireless headsets. Granted, some of these products haven't made a whole lot of sense (remember the Bluetooth remote control car?).
Others, like the HCB 300 Bluetooth car kit are indeed functional. Yet the company's MBW-100 Bluetooth Watch is a little harder to classify. It goes beyond entertainment and definitely serves a purpose, but we're still not sure if it's really necessary.
When paired with a Bluetooth phone (it doesn't have to be a Sony Ericsson model), the MBW-100 does more than just tell the time; it also displays caller ID and lets you know when you have a new message. If you don't like the person who's calling, you can reject the call. And if you're using a Walkman phone, like the Sony Ericsson W810i, you can use the MBW-100 to control the music player. Of course, you will have to touch your phone if you want to, say, pick up a call. But otherwise, you can go quite a while without looking at your handset's display. I haven't personally seen the watch, so I don't know if it will go with every outfit, but Sony Ericsson says its accessories "are designed for the modern consumer to ensure the best technology looks good too." The silver MBW-100 weighs 6.6 ounces and is available for a pricey $399.
