Seiko 5 5126-8030 Illusion dial with fluted bezel
A fun seiko 5 from the 60. Automatic movement, quickset date ( by pushing in the crown) and a special case. On the dial we can find a thing called an illusion setting. These are markers that are cut in such a way that they look like diamonds while they are just stainless steel marker.
