This is a King Seiko 5626-7041 dating to 1973. This is uncommon to find the slate original dial on these watches. The unpolished 36.75mm. sloped lug case is fabulous. The automatic high-beat Seiko movement is accurate. This vintage Seiko boasts a sapphire crystal, signed crown and quick-set day/date feature. These are very high quality watches you can wear for a lifetime.
