Mechanism (100) for a secondary additional display (2) of a first physical quantity, in which a push rod (4) actuates first means of engaging/disengaging said secondary display (2) with respect to a movement (6) comprising a first display (1), and a pivoting first-quantity heart cannon pinion (36) of which the engagement/disengagement with respect to said movement (6) are controlled by said first means. A second push rod (5) controls the zero reset of said secondary display (2) by disengaging said first engagement-disengagement means, and setting said heart cannon pinion (36) to the starting position. Second engagement/disengagement control means comprise either a pivoting time-zone runner (20) comprising, these being coaxial and able to collaborate frictionally, a friction wheel (21) meshing with said movement (6) and a time-zone wheel (25) which, when said runner (20) is in the engaged position, drives a second physical quantity heart cannon pinion (70), and/or a third physical quantity heart cannon pinion (80), or alternatively, an inter-time-zone mechanism (93). Timepiece (1000) comprising such an additional display mechanism. |
