Seiko Professional 600 Men’s Divers watch collectors item.
1979 Seiko 600 Divers watch. It is the last of the Seiko grandfather tuna original that were ever made as production ceased in that year. There is no M after 600 meaning the original model. No defects or scratches. It has not been worn much since then as band missing due to age, wear and tear. Not many of this world classic left.
