The mechanism has the hour hand fitted on to a barrel (9). It may be advanced or retarded by an hour when one of two pushbuttons is depressed, for advance or retard respectively. A correction star (11) is fitted on to the barrel, the teeth of the star being subject to the action of two control levers (13,14) controlled by the first and second pushbuttons. Around the barrel (9), is an hour wheel (15), driven by the time regulator. The hour wheel is coupled to the correction star (11) by a chain mechanism (17). On the correction wheel there is an auxiliary wheel (22) engaging an intermediate wheel (25) which itself drives a data disc. |
