Dick Tracy has finally left the comics and joined reality. Sony Ericsson’s new MBW-100 Bluetooth watch shows the caller’s name or number on its OLED display beneath the watch face. If you’re too busy fighting crime to answer the phone, you simply press a key to send the caller voice mail. You can also play music and text message. Designed in cooperation with Fossil, it is available in silver and a limited edition black, and weighs 6.61 oz.

If you already have a Sony Ericsson cell phone, the watch will alert you with an out-of-range notification when the two of you are separated. The MBW-100 will be available at the end of this year for $399 (charger included) and is compatible with Sony Ericsson cell phones K610, K610i, K618, K790, K800, V630, W710, W850, Z610, and Z710.
