    • The movement, of the conventional type with barrel (10) and spring balance, includes two time displays with hands, the hands (3m, 3h, 3s) of one of the displays, arranged opposite one of the principal faces (1) of the movement, being driven in rotation in a known manner by a gear train comprising a toothed center wheel (12) fixed onto an arbor (13) with a pinion (11) meshing with the barrel. Opposite the other principal face (2) is found another time display, the hands (5m, 5h) of which are driven by another gear train (35, 36, 37, 38, 39, 40, 41), a toothed wheel (35) of which is fixed onto the arbor (13) of the center wheel (12). This arrangement permits reducing to a minimum the height of the other gear train and to guarantee the same small backlash for the hands of both displays. The barrel spring (10) is wound by an automatic winding arrangement comprising an oscillating mass (7) arranged opposite the other principal face (2) of the movement. A time setting stem (6) capable of occupying a neutral axial position and two drawn-out positions, enables, in cooperation with a transmission mechanism (47-56), correcting the indications of one of the displays in one of the drawn-out positions and the indications of the other display in the other drawn-out position.
    • 具有桶(10)和弹簧平衡的常规类型的运动包括两个具有手的时间显示器,一个显示器的手(3m,3h,3s)布置在与其相对的一个主面(1) 运动通过包括固定在具有与筒体啮合的小齿轮(11)的心轴(13)上的齿形中心轮(12)的齿轮系以已知方式驱动。 发现另一个主面(2)的另一个时间显示,其中(5m,5h)由另一个齿轮系(35,36,37,38,39,40,41),齿轮(35) )固定在中心轮(12)的心轴(13)上。 这种布置允许将另一个齿轮系的高度减小至最小,并且确保两个显示器的手的相同小的间隙。 筒形弹簧(10)由包括摆动块(7)的自动卷绕装置卷绕,摆动块(7)布置成与运动的另一主面相对。 能够占据中立轴向位置和两个拉出位置的时间设定杆(6)能够与传动机构(47-56)配合,在一个拉出的位置中校正其中一个显示器的指示 位置和另一个显示在另一个拉出位置的指示。
