Thank you for viewing. This is a retro, simple, and elegant NATIONAL wall clock. It runs on one size D battery. It's a smooth, silent movement type, not a ticking one, but it's a transistor type. Fine adjustments to the time can be made with the + and - on the movement. It's simple, but the design is unique and stylish. Currently, the clock runs, but it's running slow. I think it can be fixed with adjustment, and someone knowledgeable might be able to do internal maintenance. Please understand the current condition. - Brand: NATIONAL - Color: White - Design: Square - Battery type: D battery - Features: Gold hands and indices Thank you for viewing.
