7 inches in diameter.  Runs smoothly and silently.  Made by the Waterbury Company - Lux brand.  Nice midcentury kitchen clock for your collection.                   

Domestic shipping and handling in the U.S. is $10.50.  Foreign bidders are welcome with the shipping costs to be determined solely by Ebay International Shipping.   I will combine shipping. I have decided to sell my collection of antiques (and other nice items), which I have been collecting for the past 30 years.  Good luck with your bids.
