This table clock works and runs on one AA battery and also is an alarm. It measures 6 1/2" wide by 6" high and 3 1/2" deep. There are several imperfections that don't really show, but if you look closely, they are there. It was purchased new with those flaws and is priced with them in mind. The last photo shows one of those imperfections in a close-up. The back panel slides up and off for access to the alarm, etc. This is a striking clock with a timeless style.
