A timepiece is set by transmission of a time related signal which is received by the timepiece and converted into digital form. The circuit developing signals representing the time displayed by the timepiece is stepped more rapidly than normal and simultaneously compared with the time related signal until they compare at which time the rapid stepping of the timepiece is abruptly terminated and normal stepping of the timepiece is resumed. The carrier may be any supersonic frequency. Setting of the timepiece may be enabled only after operating a time check switch. The above technique may be employed to produce an alarm at a requested time to serve as a memory or wake-up aid, for example.
