Music is pre recorded on a chip. Sounds like movie score. It is not super loud, but ok. Watch has 2 batteries, 1 for time, and 1 for music. Video on you tube.
I received the watch yesterday. Very nice presentation box. Watch has good weight, and has a beautiful case and chain. Sitting in a chair, with three fingers of bourbon in a glass, and playing the tune, takes you right into the movie. I highly recommend buying one. You'll be a daisy if you do! Montana
