This is a cute, retro-designed, compact alarm clock. It also looks great as room decor. I was using it as a desk clock, but I'm selling it because the style of my room has changed. Height: 125mm x Width: 78mm x Depth: 50mm Step movement (the second hand moves every second) It has an alarm function and a night light. It runs on one AA battery. Operation has been confirmed. *For safety during transport, the battery will be removed before shipping.
