Watches aren't supposed to be USB compatible, but don't tell that to the Music Watch with USB. This straightforwardly named watch was designed by Shaheem M to be a combination music player and time teller.
The Music Watch with USB has a digital display, with a face that is separated into two halves. The top half tells the time and date, and the bottom half tells you what song is playing. The watch itself is made up of two separate USB drives that can be connected to a computer for charging and transferring music. The watch is designed without a headphone jack, but it does have Bluetooth capabilities. The iPod Nano proved that an MP3 player would be accepted as a watch.
