CITIZEN | 40-4055- AKA [Crystron LC]
RELEASED | 1978
The 9180 Calibre was a successor to the popular and similar looking 9080. The 9180 moved the design to a slim fibreglass PCB based movement and added three Mode indicators to the LCD display (Calendar/StopW/Time2) with the gap between the time display and the horizontal dividing line increased slightly to accomodate them. Note that none of the new indicators are visible in the normal time display. Strap correct-period Citizen example but is not original to this watch.
