Abstract

Die Uhr besitzt eine digitale Datumsanzeige (1), die zwei Ziffern (10, 18) in einem gemeinsamen oder zwei getrennten Fenstern aufweist. Eine Zehnerzifferscheibe (3) trägt einen ersten Zahnstern (4) und eine Einerzifferscheibe (2) einen zweiten Zahnstern (5). Die beiden Zahnsterne (4, 5) sind mit einem auf einer Platine (6) gelagerten Schaltring (7) in Eingriff, der von einem Datumsschaltrad (8) angetrieben ist. Der Schaltring (7) weist Schaltzähne (9) zum Drehen der Einerzifferscheibe (2) auf. In Drehrichtung des Schaltrings (7) gesehen ist nach einem ersten Schaltzahn (9a), der die Einerzifferscheibe (2) vom 30. auf den 31. schaltet, auf dem Schaltring (7) ein zweiter Schaltzahn (9b) angeordnet, der bezüglich der Einerzifferscheibe (2) unwirksam ist. Der zweite Schaltzahn (9b) ist vorzugsweise so gesteuert, dass er im Bereich der Einerzifferscheibe (2) so bewegt wird, so dass er mit dem zweiten Zahnstern (5) nicht in Eingriff kommt. Die Erfindung ermöglicht ein Grossdatum mit vergleichsweise wenigen Einzelteilen, wobei die Datumsanzeige vorzugsweise als Modul ausgebildet ist.
