<p>A watch with superimposed dials, comprising a diaphragm (8), placed between a lower graduated dial (7) and an upper graduated dial (19), which, by means of an external operation, can be opened and closed rendering lower dial (7) legible or illegible. The diaphragm (8) is composed of a plurality of thin mobile plates which can be partially superimposed on one another and are suited to rotate between a position of reciprocal engagement in which the diaphragm is closed, and one of disengagement in which the diaphragm is open. <IMAGE></p> |
