The Analog Alarm Quartz Watch 7223 is easy to operate and rings precisely on the time set. This Caliber is developed first in the world for customer who likes to have an analog watch. (Novenber 1979) The most important point in the development of this watch is to minimize the variation of the contacting time of alarm contact points that is to set the contacting time of alarm contact points correctly between the standard pulse signals for alarm (Five-minute interval) given out from the electric circuit. This alarm system is so designed that it sings when the first standard alarm pulse signal is generated after the closing of alarm contacts.
