Abstract

An electronic timepiece, in particular, a battery-operated quartz wristwatch including a housing in which there is arranged an analog display mechanism as well as a liquid crystal display unit which facilitate a display of different time magnitudes. The display surface of the liquid crystal display is practically as large as the watch dial surface of the analog display mechanism. The liquid crystal display unit is arranged in the housing of the watch in front of so as to superimpose the analog display mechanism. Preferably, the liquid crystal display is transparent and constructed as a replacement for the usual watch crystal as the generally viewed protective cover for the watch housing.
