<p>The movement, of the mechanical or electronic type, is delimited by two main faces (8, 9), and it comprises two analog time displays. The first, corresponding to the conventional display, includes two hands (4, 5) moving in front of one of the faces (8) about a pivot pin (aa') perpendicular to the two faces, and it is driven in a known manner by cogwheels (19, 23, 25, 26) from the minute shaft (15). The second display comprises two hands (4', 5') moving in front of the other face (9) about the same pivot pin (aa'), and it is driven, in the opposite direction, by a gear train (36, 40, 41, 23', 19', 25', 26') from a moving element (23) of the cogwheels of the first display. Moreover, a cannon pinion (37), enabling the second display to be locked by means of a control member (50), is arranged between two moving elements (36, 40) of the gear train. Conventional means make it possible to set the time simultaneously and in synchronism on the two displays if the control member (50) is inactive, and on the first display alone if this member is activated. <IMAGE></p> |
