Remarks This Lord Matic offers an incredible combination of a flawless blue dial, a sharp case, and the highly desirable faceted crystal. It is a fantastic representation of Seiko's mid-century design language, offering immense wrist presence and collector appeal. History Introduced in the late 1960s, the Seiko Lord Matic (LM) series was designed for the ambitious professional, offering a high-quality automatic movement in a more accessible package than the flagship Grand Seiko and King Seiko lines. The 5600 series movements used in the LM range were highly regarded for their slim profile and reliability, eventually serving as the foundational architecture for many King Seiko models. Throughout the 1970s, the Lord Matic line became a canvas for Seiko's most expressive and experimental designs, featuring vibrant colored dials, unusual case shapes, and elaborately cut faceted crystals that have since become iconic markers of the era's horological aesthetic.
