Rock crystal was not the only mineral used for making watchcases in Geneva, and Charles Bobinet was noted for supplying movements for cases made of various kinds of hardstone. The cases often exploited patterns in the stone, as in this example. Equally effective is the pristine white enamel dial, clearly calibrated to show fifteen-minute intervals indicated by the single hand. These dials were derived from the dials of the watches with enameled cases originally developed in France.
