<p>The unit has a body comprising upper and lower cases (1, 2). The cases have respective display units (16, 26) at their front sides. A clock work has two parts housed in the cases for driving the display units, respectively. The case (1) is superposed on the case (2) and is rotated with respect to the case (2) to cover/uncover the front side of the case (2), in closed and open positions, respectively. The two parts of the clock work are provided with a kinematic connection by a driving mechanism. The kinematic connection between the parts is interrupted when the cases are handled in the open position.</p> |
