For this purpose, it is intended to derive the imitation pulse sequence (7) from the time-holding electric circuit (12) for the clock time display device (2) and to emit these sequences electroacoustically via an audio final stage (15), for example by means of a cushion loudspeaker (8) connectable via a cable (10,. The imitation pulse sequence (7) is preferably obtained directly from the sequence of the switching pulses (13) of a stepping motor drive for a seconds hand, from which a pulse shaper circuit (17) can generate the double pulses characteristic of the heartbeat. With a bipolar stepping motor drive a bridgeable diode (19) results in a simple switching means between low and high frequency of the imitation pulse sequence (7).<IMAGE>
