The crystal is well-preserved, maintaining clear visibility of the dial beneath while providing the distinct architectural depth that makes this reference so highly sought after. The screw-down caseback is clean and fully legible, clearly displaying the factory engravings, reference numbers, and the Suwa factory emblem.

Remarks Finding a Seiko Lord Matic with a pristine colored gradient dial and an intact faceted crystal is an increasingly rare occurrence. The combination of the deep green sunburst finish, the complex light play of the crystal, and the reliable 56-series automatic movement makes this an incredibly attractive piece for any vintage enthusiast. It perfectly encapsulates the bold and innovative design language that defined Seiko in the 1970s. History Introduced in 1968, the Lord Matic (LM) line was positioned as a premium offering in Seiko's catalog, heavily utilizing the sophisticated 56-series movements that would later be adapted for use in King Seiko and Grand Seiko models. The Lord Matic series was the canvas for some of Seiko's most adventurous and varied designs, frequently featuring vibrant colored dials, faceted crystals, and complex case geometries. Produced during a period of intense internal competition between the Suwa and Daini factories, the Lord Matic represents a high-water mark of mid-century Japanese horology, combining superb mechanical reliability with striking, forward-thinking aesthetics.
