<p>The wrist-watch has a case (11) with a clock mechanism (16) for controlling rotational movement of hands (18, 19) around a central axis to indicate hours and minutes. The case includes an aneroid frame (13) for carrying a lever (14) that extends parallel to the central axis and controls the movement of a hand (15) to deliver information representing the pressure applied on the frame, where the frame has diameter lower than 35 mm. The frame is made of beryllium copper and welded with zinc under vacuum. The frame is located between a bottom (111) of the case and the clock mechanism.</p> |
