This is a King Quartz. The crystal has scratches. It was overhauled about a year ago, but I haven't used it much since then. The date change can only be advanced. I'm not sure if this is a malfunction or normal, as I don't know much about it. I am selling it to organize my collection. I will ship it in simple packaging. 0852-8020G - Brand: SEIKO - Model: Quartz - Color: Silver - Features: Date display function - Features: - Condition: Slight scratches on the dial Thank you for looking.
