This is a SEIKO clock. Model number: TZ-630 It features a green radial dial with three-dimensional floral decorations, giving it a Showa retro feel. It is a transistor clock that operates on one single dry cell battery. I have confirmed its operation with a battery inserted, and it is currently keeping time correctly. The original SEIKO label remains on the back, and paper documentation, likely records of battery replacements and inspections from the time, can also be seen. There are scratches, stains, and color changes in the decorative parts due to aging, but there is no significant damage. Please check the condition in the images. Please purchase only if you understand that this is a Showa retro item and a used item.
