Abstract
The invention provides an electronic watch having an analog display with time indicating hands, a digital display and control means including a crown adapted to act on contacts arranged so as to provide signals representing rotary and axial displacements of said crown to an electronic selection and correction circuit. Responding to movements of the crown, the electronic circuit determines the operating mode of the watch and modifies the indications given by the displays. In a special synchronizing mode the two displays are set to indicate the same information and the analog form thereof may be adjusted to coincide with the digital form.
