Thank you for viewing. This is an alarm clock with a classic design. It has a style that easily matches interiors. It's a Showa-retro Orient Travel Watch. It has an alarm function, making it convenient for travel and daily use. It's compact and easy to carry. The diameter of the clock face is approximately 6cm. The overall diameter, including the cover, is approximately 7.5cm. It has been stored for a long time without being used, so there is some age-related deterioration, and fading of the instruction manual, the main body, and the outer box. Thank you for your understanding.
