A solid state watch with electrooptic display employs digital indication of hours and five minute radial markers for indication of minutes. A first selected marker is actuated during five minute intervals and second markers are modulated in varying spaced relationship to the first marker, so as to give an indication of the degree of passage of time during five minute intervals.
