【Extremely Rare】CITIZEN CHRONOGRAPH DUAL TIME Watch Battery replaced, operation confirmed. The small light bulb also works perfectly. The layout of the dial is unique and cool. The brown coloring is unlike anything today, giving it a retro-future feel and making it very cool. Features include a watch, chronograph, and calendar functions. On the watch screen, the corresponding day of the week and AM/PM are displayed above. On the chronograph screen, numbers from 0 to 9 are displayed, counting tenths of a second. The liquid crystal display below the numbers flows, which is cool. The calendar screen displays "CALENDAR." It's thoughtful (lol). The back cover is a highly airtight screw-back. There are signs of use, scuffs, and scratches, but a fully functional one is hard to come by. The wrist circumference is about 17.5cm.
