The addition of the English and Kanji day wheel makes it a particularly appealing example of 1970s Japanese watchmaking. History Introduced in the late 1960s, the Seiko Lord Matic line was positioned just below the King Seiko and Grand Seiko ranges, offering premium automatic movements and sophisticated case designs to the discerning public. The 5600 series of calibers became renowned for their thin profile and reliable performance, eventually forming the basis for many higher-end Seiko models of the era. Today, the Lord Matic remains highly appreciated by collectors for its exceptional build quality and diverse array of dial variations.
