The Chromatic Watch Company has been selling unique, musically themed time pieces around the world for more than 30 years. In addition to being attractive, quality timepieces, our products will help you to learn many aspects of music theory, everything from the circle of fifths, circle of fourth and chromatic scales to chords, intervals, keys and progressions. The circular shape of our products illustrates the circular nature of music theory in a way that is easier to grasp than a linear approach of explaining these concepts.
