Abstract: The present disclosure relates to a chronograph-watch comprising a timepiece mechanism. The timepiece mechanism includes: a current time mobile comprising an axis and being arranged to rotate about this axis, a first mobile comprising an axis and being arranged to be connected to the current time mobile, an indicator member, a second mobile arranged to mesh with the first mobile and to be connected to the said indicator member, an element bearing a scale comprising a set of indications, the indicator member allowing information to be displayed on this scale. The mobiles are arranged so as to obtain a gear ratio between the mobiles which varies as a function of their relative angular position, so that the indicator member rotates with a variable rotational speed in correspondence with at least one subset of said set of indications.

Abstract: Reversible watch, comprising a case (1) provided with a first face (10) for displaying first time indications and a second face (11) opposite said first face. A turning-over mechanism (20, 21, 22, 23) allows the case (1) to be turned over around a turning-over axis (201-211; 221-231) parallel to the 6 o'clock-12 o'clock axis so as to display at the wearer's preference either the first face or the second face. The turning-over mechanism comprising a pivoting arm (20, 21; 22, 23) on each side of the case that allows the turning-over axis to be moved back. The case (1) is connected with the arms (20, 21; 22, 23) to be able to pivot around the turning-over axis (201-211; 221-231). The length of the arms is sufficient for turning over the case without the winding button or other buttons coming into contact with other parts (17) of the watch.
