Acoustic timepiece display mechanism with a chronograph repeater for the acoustic display, by a striking mechanism, of a duration measured by a chronograph mechanism, this striking mechanism including a winding lever for driving a rack to move a striking rack in order to read the magnitude concerned and to release a corresponding strike function, this acoustic display mechanism includes, between the mechanism controlling the chronograph mechanism and the winding lever, a mechanical connection arranged, depending on the position of a control cam of the chronograph mechanism indirectly defining a variable secondary direction of the winding lever, to isolate or not to isolate the winding lever from a winding pusher operated in a single pusher direction by a user to set off the acoustic display of the timed duration. 1. An acoustic timepiece display mechanism with a chronograph repeater for the acoustic display , by a striking mechanism , of a duration measured by a chronograph mechanism , said chronograph mechanism comprising a control mechanism including a control cam whose position is variable , and said striking mechanism including a winding pusher arranged to be operated in a single pusher direction by a user to set off the acoustic display of the duration timed by said chronograph mechanism , said striking mechanism also comprising a winding lever arranged to drive a rack to move a striking rack to read the magnitude concerned and to release a corresponding strike function , wherein said winding lever is arranged in a variable secondary direction , and in that said acoustic display mechanism includes , between said control mechanism and said winding lever , a mechanical connection , arranged , depending on the position of said control cam , to isolate or not to isolate said winding lever from said winding pusher.2. The acoustic display mechanism according to claim 1 , wherein said striking mechanism includes at least one said striking rack formed by a minute rack ...
