Crashing triumphantly back into the top spot comes Sony Ericsson's Bluetooth watch, this time with a makeover and improved battery life. It's capable of pairing with your mobile to give you incoming call warnings and caller ID - check your watch when someone's calling and then reject them if It's no-one you want to talk to. And it doesn't stop there: the MBW-150 lets you skip and pause tracks on your music mobile, if it's compatible. The only downside is that this will be the first watch you've ever had to charge up.
