Abstract

The display mechanism provides a large-size date display for a watch through a window, utilizing a first digital support disk (A) including units and graduated at least from 0 to 9 and second digital support (B) in the form of an arc segment for displaying the tens, i.e. 1-3. The disk describes at least an arc driving the digits beneath the window based on the selected time unit. The second arc segment describes an arc whose center is placed outside a circle formed by the support disk, so that the figures of the tens are spaced apart by a non-obstructing zone revealing the first disk. The second arc segment is urged to be superimposed on the first disk to form the two digits of a date number.
