FIELD: physics; clocks.
SUBSTANCE: invention relates to a device (100) for an auxiliary display (2) for displaying a first physical quantity, the pusher (4) of which actuates first engagement/disengagement means of said auxiliary display (2) with a mechanism (6), comprising a first display (1), and a rotary axial platform (36) of the first physical quantity, the first means of which control engagement/disengagement with said mechanism (6). A second pusher (5) controls zero setting of said auxiliary display (2) through disengagement of said engagement/disengagement means and through fixation in the initial position of said axial platform (36). Second engagement/disengagement control means either comprise a rotary movable drive (20) of the time zone, having, arranged coaxially and capable of interacting with each other through a frictional bond, a frictional wheel (21), which engages with said mechanism (6), and a time zone wheel (25) which rotates, in the engagement position of said movable drive (20) of the time zone, an axial platform (70) of a second physical quantity and/or an axial platform (80) of a third physical quantity, or a inter-zone device (93). A clock (1000) having said auxiliary display device.
EFFECT: improved design.
