USB watch

The USB plug is cleverly integrated into the watchstrap (and looks pretty cool). It is easy to remove and guarantees that you'll be able to connect whenever and wherever you need to. Simply plug the USB watch into the USB port on your computer and it can be used like any other drive on your machine. Then work on files as you would on your hard drive. You can drag and drop items into it, save documents straight into it and then open the documents straight from the watch and work on them on a different system.
