This is a real 3 1/2in computer Hard drive that has been transformed into a working desk clock using a USA made quartz drive movement and acrylic stand. The clock measures 4"w x 6"h, and runs on 1 AA battery, included. It will make a great conversation piece on your desk or a special gift for that geek you know who is so hard to shop for. Since these clocks are made from recycled computer parts, there will be signs of use and age. Thanks for looking. **SHIPPING** USA: USPS Priority with delivery confirmation.
