摘要

An autonomous electric watch comprises a receiver for picking up a magnetic or acoustic coded regulation signal delivered by a telephone set, and a control circuit automatically controlling memory circuits of the watch to regulate the frequency and/or set the time displayed in response to reception of such a signal. The regulation signal is provided by a signal generator connected to an automatic telephone reply apparatus that can be called from any subscriber telephone set, and may be combined with a pre-recorded spoken message giving instructions to the caller.
