This beautiful Anniversary clock silver tone is currently working with globes spinning. It does lose time and there is no key. It could be gone over by a clock repair person. These clocks are known for quality made in Germany this model in January of 1954 as it is stamped on the back. These clocks are called 400 day clocks as they are meant to be wound just once a year. You will have to buy this as is. I will keep the price in line with possibility it can only be used for parts or display. As far as I know no music
