This clock was made using a recycled Kodak Slide Carousel, DVD and a new quarts drive movement. Mixing a little bit of the old with the new. It's hard to believe how many trays of slides would now fit onto just one DVD. The clock measures approximately 9.5 inches in diameter. This is not a photo of the actual clock, but it will be the same model and style. Because these are made from recycled items, there will be signs of age and use. It will make a great conversation piece on your wall or great gift for that Camera buff/ photographer you know who is so hard to shop for. It runs on 1 AA battery (included). Thanks for looking.
