Abstract
According to this method the units and tens numerals are placed onto respective indicator runners (1, 2). Two drivelines are formed, one being a daily driveline between the clock movement and the indicator runners, for moving the units indicator runner (1) selectively step by step by one step every 24 hours, and for moving the tens indicator runner (2) by one step for every ten steps of the units indicator runner (1), in order to move on from one multiple of ten to the next, and for moving the tens indicator alone by one step to move on from '31' to '01' on a 31-day cycle, and an annual driveline between the clock movement and the tens indicator runner, which driveline is programmed to move the tens indicator runner (2) by one step at the same time as the units indicator runner (1) is moved by the daily driveline, to move on from '30' to '01' at the end of the months which comprise less than 31 days.
