Recommended reason:
    The gold case watch was once ‘recognized’ as an upstart watch because of its color. The beauty of this Frank Muller day and night retrograde watch is that the designer moves the two ‘semicircles’ that are concentric under normal circumstances up and down with the center axis as the origin. The two semi-circular dials represent ‘day’ and ‘night’, and alternately rotate around the arc. When they reach the end point, they quickly jump back to the starting point and turn to the other half circle to start the time.
