In the 1920s, the designers created the ball watch that was enameled and made with fine metal. In the 1950s, it was recreated into a huge fad that most fashionable women had to have. We have a working watch set in a black enamel ball with a cream face. I've always considered this watch special. It measures 7/8" by 7/8" diameter, the watch face ½“ by ½“ and the chain measures 24" in length. It is in excellent condition.
