This is a retro alarm clock that has been stored in a dark place for a long time. It's a spring-powered clock, which is rarely seen these days. When you turn the knob on the back, the spring winds up and it starts ticking with a cute sound. The alarm does go off, but I don't know how to stop it halfway through ^^; I'm also unsure how to use the power outlet. The exterior is in relatively good condition for its age. Please understand the above before purchasing. I think it would be a great addition to your昭和-era interior decor (^o^) Height: 12 cm Width: 18 cm Depth: 6 cm A retro CITIZEN desk clock with a green plastic body and a floral pattern. - Brand: CITIZEN - Color: Green - Design: Analog display - Features: Alarm, switch (ON/OFF) - Style: Retro - Material: Plastic Thank you for looking.
