This clock was created using a recycled bike crank gear set, some bike chain, and a new quartz drive clock movement. Since these clocks are made from recycled bike components, they will have signs of use and age, with scratches, dings, oxidation, etc. The gear has been cleaned thoroughly, repainted and ready for display. The clock measures approximately 7 inches in diameter. It will make a great conversation piece on your wall or great gift for that biker you know who is so hard to shop for. It runs on 1 AA battery (included). Thanks for looking. **SHIPPING** USA: USPS Priority with delivery confirmation, 2 to 3 days.
