Abstract

An electronic timepiece with hands 1, 2 has a plurality of auxiliary digital displays 5, 6 and 7 for indicating the same parameter, e.g., the day of the month. Only the digital display not interfering, at a given moment, with the analog time display is activated by a control circuit which decodes which of three sectors a, b and c are occupied by the hands. The display in the unoccupied sector, or one of the two unoccupied sectors, is always selected.
