* Case approx.: 28x37 mm * Thickness approx.: 8.2 mm * Belt size: 200 mm, width approx.: 20 mm This item is a rare vintage SEIKO from the 1970s. Its main attraction is the beautiful green dial with a deep gradation. This color, which changes its appearance depending on the light, gives a retro feel that is not found in current products. It also features the popular tank case, which makes the wrist look smart and elegant. Despite being an automatic (self-winding) model, the fact that it achieves this thinness and size is proof of SEIKO's high technical ability at the time. The serial number "381260" on the back cover confirms that it was manufactured in August 1973. As a watch from half a century ago, it is in very good condition, and it also comes with a genuine SEIKO metal bracelet, making it a valuable collector's item.
