Citizen Crystron LC 40-6015

It's an old but simple watch for me today.

This one is an old LCD watch by the Japanese watch giant Citizen. It is part of their original Crystron LC range which were their first line of quartz digital watches. The Crystron name had been around earlier covering quartz analogue watches, and the LC part was added designating the LCD display.

This model (I'm assuming) is from 1978. I've based this on the serial number, and that the date input starts at 1970. Citizen didn't assume that this model would be around for this long as the date input actually finishes at 2009 before going back round to 1970 again.

It has a 5 1/2 digit LCD display with the PM marker above the smaller seconds digits. The module is a 6015, which is a basic module having only time, date, and seconds displays (but there is also a bulb based light). The full model numbers are 4-097181 and 40-6015.

Design wise, the watch is also very simple with a slightly rounded case, simple LCD display, and a pattern of alternating blue and mirrored stripes on the face. The front also has the Citizen Quartz Crystron LC name as well as the CQ symbol of the Citizen Quartz range. The strap is quite plain with the Citizen name only on the inside of the clip, and has a part number of 2477.
