It is spring driven (no battery required!), and comes with a protective face cover as well as a removable winding key. Measuring only 2 inches deep, 1 inch wide, and 4 inches high, this metronome is portable, and will fit inside nearly any instrument case or music bag. The tempo range is from 40 beats per minute to 208 beats per minute. If you want an analog metronome (no batteries!), then this is the one that we recommend.
