Thank you for viewing. CITIZEN Precision Constellation Display Clock 4MY602-008 model: M602 Extremely rare. This is the final model in the wall-mounted Cosmo Sign series. The constellation dial uses luminous paint, and when exposed to light and then moved to darkness, a starry sky appears. This item is a store deadstock item from a watch store. It is approximately 20 years old, and while there are some scratches from storage, it is in beautiful condition. There is no dust or mold inside the crystal. I have checked the operation before listing, and it works without any problems. Accessories Original box Instruction manual
