FIELD: watches and other time measuring instruments.
SUBSTANCE: hourly movement (500) of acoustic indication with a repeater mechanism of a chronograph for acoustic indication, by means of combat mechanism (1), a time interval, measured by mechanism (100) of a chronograph, wherein combat mechanism (1) comprises crank (39) for actuating comb (33) for moving the comb pressure in order to read the corresponding value and start the corresponding combat function; this acoustic indication mechanism (500) comprises a mechanical connection located between the mechanism, the chronograph control mechanism (100), and winding lever (39), which, depending on the position of control cam (60, 54) of chronograph mechanism (100), indirectly determining variable second direction (B) of crank arm (39), isolates or does not isolate winding lever (39) from winding pusher (390) driven by user in single direction (A) of pusher to start acoustic indication of time interval.
EFFECT: repeater mechanism of chronograph with safety function is proposed.
