The item is marked as being from December of Showa 63, which suggests it was manufactured approximately 37 years ago. Considering its age, the condition is good. I tested its operation for about a week before listing it, and it did not lose or gain more than a minute. It functions correctly as a clock. The second indicator pilot lamp also blinks normally. When the light button is pressed, a dim light bulb illuminates. * The alarm did not sound. It is uncertain whether this is due to a malfunction or incorrect settings. Please refrain from purchasing if you are not interested in or do not understand old items and vintage goods.
