Abstract

Abstract In an electrically activatable display system in a timepiece the first two letters of each of the days of the week are selectively activatable electrically. The letters consist of segments so disposed in relation to each other that at least one segment can be used in the formation of a plurality of letters. The system can be modified to display the first two letters of the days of the week in any of a number of languages.
