Thank you for viewing. This is a Seiko BELL-MATIC, one of the watch collection my father cherished, which I inherited. I am not knowledgeable about watches, so I may not be able to answer specialized questions, but it is currently running. The SEIKO BELL-MATIC was manufactured in the 1960s-70s, and is a rare domestically-made automatic watch with an alarm function, which was a popular model back then. Due to its age, there are fine scratches and scuffs from aging. Please check the images for the condition of the exterior. *Please refrain from purchasing if you are sensitive to these details. I would be happy if someone who understands antique items would purchase it. As it is a treasured item that my father cherished, I hope to pass it on to someone who will take good care of it. *There are no pets in the house, and there are no smokers. For those who like it, collectors, how about it? Thank you for your consideration.
