14" dia, 3¼" thickness. Heavy gauge steel case and thick glass. Works perfectly and keeps time correctly. This is not a quartz movement clock. The electric motor is timed to 60hz household current. The second hand revolves smoothly and you can see the minute hand moving if you watch it closely! The clock is in excellent condition. I did not clean this in case you prefer it in original condition. It is not very dirty at all. My husband and I sell only quality items that have been cleaned and tested unless otherwise stated. We offer very reasonable prices, yet most of our items are negotiable so don't be shy! You're going to walk away happy - that's what we look forward to!!! Cross-posted, first come first served - no holds. We're sorry if our schedules or localities don't coordinate and someone else purchases the item(s) first. It's nothing personal :) We do accept PayPal and/or FB messenger payment to hold your item for 24 hours. NO REFUNDS unless item is damaged in our possession. Have a happy, blessed day! Christine 😊
