Swap Signature mobile phone watch

Whether you're short on pocket space or just looking to cart less stuff around with you, Swap's new watch phone could be the answer.

Slip in your existing SIM card and you can use it not only to tell the time but to make phone calls, too. It'll last for up to 180 minutes of talk time or 100 hours of standby and there's a USB connection for easy charging.

You can pair it with a Bluetooth headset if you'd rather not talk into your wrist and there's a 2GB MicroSD card included for storage.

The Signature will be available soon for 349.99 without contract, see Swap for more information.
