The promise of Bluetooth was that one day we'd carry around digital devices that were all in communication with each other. The Sony Ericsson MBW-150 Music Edition is a rather clever watch that tries to deliver on this promise.
It costs around £200 and has Bluetooth onboard so it can stay in constant contact with your Sony Ericsson phone.
Sony Ericsson actually offers three versions of the watch: the Classic, Music and Executive. They all share the traditional rounded face design and are waterproof to a depth of 30 metres, but come in different colour schemes and with different straps. We had the Music Edition, which is supplied with a black rubberised strap and has orange flashes to match the company's Walkman range of phones.
To charge the watch, you attach a plastic spring-loaded clamp that snaps into place on the left hand side of the watch face. After around two hours, the watch will be fully charged and you can then pair it with your phone.
The pairing process is fiddly, but when it's completed you shouldn't have to repeat the process again. Once paired, the two stay in contact with each other as long as they're within a 10 metre range.
The watch has a small single line OLED display that's used to show text and icons. For example, when an incoming call is received, the watch vibrates and shows either the name of the caller if it's in your phone's address book or the number if it's not. You can mute the call by pressing the top right button once or reject it by pressing the button twice. The watch also notifies you with a vibrate and an envelope icon when you receive a new text message.
We reckon the watch's most unusual feature is its ability to control your phone's music player. The music controls are spread across three buttons on the left hand side of the watch. To start a track playing you press and hold the centre button and to stop playback you quickly press it once. The other two buttons act as volume controls or track skip buttons when you hold them in.
