Abstract

A counter logs the number of vibrations per second of the generator of periods and records it in a memory of the watch, which is part of the readjusting device. Whenever the number of vibrations reached corresponds to that entered into the memory, a signal is transmitted to the liquid-crystal analog display, the counter of the number of vibrations is then reset to zero and a new normal counting cycle is started. An apparatus for transmitting low-frequency radio waves produces synchronisation signals acting on the readjusting device of the watch, if it is within range of the transmitter. Resetting the watch to time on passing in front of the shop of a retailer keeping his transmitter going. <IMAGE>
