<p>#CMT# #/CMT# The watch has tooth star parts (4, 5) engaged with a switching ring (7) that is mounted on a printed circuit board (6). The switching ring is activated by a data notched disk, and includes actuation teeth (9) for rotating an unit's digit disk (2). One of the actuation teeth (9a) is arranged on the unit's digit disk, and is viewed after other actuation teeth (9b) in a rotational direction of the switching ring, where the latter actuation teeth switches the unit's digit disk from 30 to 31 point. The former actuation teeth is ineffective with respect to the unit's digit disk. #CMT#USE : #/CMT# Watch. #CMT#ADVANTAGE : #/CMT# The watch is designed in such a manner that a date display function is realized with a simple switching module in a safe manner without need for an expensive drive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a watch. 2 : Unit's digit disk 3 : Tens disk 4, 5 : Tooth star parts 6 : Printed circuit board 7 : Switching ring 9, 9a, 9b : Actuation teeth.</p> |
