This is clock made out of a recycled hard drive & a brand new quartz clock movement. This desk clock measures approximately 6'' x 4'' (15cm x 10cm). Runs on 1 AA battery. We can offer a custom engraving of your choice on a small, brushed metal plate affixed to the back of the clock. It is made from recycled materials & may show some signs of previous usage. It will make a great gift for any tech lover or someone who already has everything. It also looks great & will make a great conversation starter in your home or work place. & of course, it tells time! :) Check out my other stuff: clocklight.etsy.com Thank you for looking, & if you have additional questions don't hesitate to ask, I'm here to help.
