Neat looking piece for a restaurant or store!
When I purchased the clock the Synchron electric motor was installed. I spliced a cord onto it and the motor turned. I could not get the hands to properly tighten, so I replaced with a battery plus, the motor had two small screws attached to the faceplate. Glass has no mounting brackets, held by the screws and tape.
No guarantee on the Synchron!
