Abstract

The digital timepiece display comprises a number of segmental display regions (12...15) for displaying respective numerals and a data display (11) using a rectangular array denoting the dates of the month of corresponding size to the display zone. The date array may have seven or fourteen columns (11a, 11b...) with the dates in the columns positioned to lie between the display numerals of the time display. The timepiece display may also incorporate a weekday indication, e.g. using selectively energised indicia (17a...17g) each corresponding to one day of the week.
