I am selling this item to organize my collection, as I have too many sports models. No need to leave a comment; you can buy it directly. Price reduced from 42,500 yen to 39,800 yen. For sale: Rare, working Seiko Bell-Matic Octagon with an inner blue dial. *Please note that I may remove this listing suddenly as I am still considering selling it. This model was manufactured for export in the 60s and 70s and is a high-spec model featuring a day-date function and a bell mechanism. It has been stored in a drawer for about 12 years after an overhaul at a local watch store. The watch has been tested and is working, and the bell also rings. While many domestic Bell-Matic watches are available, the octagon case is rare and not often seen. Why not add it to your collection? ● Condition: Working without significant errors for a vintage watch. ● Day and date adjustment: No problems. ● Bell: Works. ● Mechanism: Automatic winding. ● Belt: Equipped with a Seiko genuine stainless steel bracelet. Fits a wrist size of approximately 17 cm. ● Please check the images and make your judgment as this is a used, vintage item and shows signs of wear. I hope it goes to an owner who will cherish it. *Please refrain from copying and pasting the images and text. This is also prohibited by Mercari's rules, and I will report any violations.
