Dial and Hands
The dial is a breathtaking green sunburst that transitions into a deep, dark vignette toward the outer edges, catching the light beautifully from every angle. It features applied, highly polished faceted indices with luminous plots at their base, complemented by matching applied "SEIKO" and "LM" logos. The silver-tone faceted baton hands feature black central stripes and luminous inserts, perfectly matching the dial architecture. A sharply framed day-date aperture sits at three o'clock, displaying a highly desirable English and Kanji day wheel. The dial remains remarkably clean, free from notable spotting, moisture damage, or print loss, presenting a stunning and vibrant face that defines the character of this timepiece.
Case and Crystal
The 37mm stainless steel case showcases Seiko's renowned "Grammar of Design" principles, featuring broad, sharply angled lugs with a distinct brushed finish on the upper surfaces and high-polish case flanks. The transition between the brushed and polished areas remains crisp and well-defined, indicating honest vintage preservation with only light, superficial handling marks consistent with careful wear. The watch is fitted with a dramatic faceted crystal that creates mesmerizing optical distortions over the green dial. The crystal is in excellent condition, allowing a clear view of the dial beneath its geometric cuts. The original crown is nestled cleanly against the case side. The screw-down caseback displays crisp, fully legible factory engravings, including the reference and serial numbers alongside the Suwa factory logo.
Movement

Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. The timegrapher results show a deviation of -14 to -18 seconds per day.
Strap

Condition
Excellent vintage condition. The case retains sharp geometry and factory finishes with only minor superficial scratches typical of normal use.

History
Introduced in 1968, the Seiko Lord Matic series was a cornerstone of Seiko's mid-to-high-tier lineup, heavily influenced by the Taro Tanaka "Grammar of Design" rules that governed Grand Seiko and King Seiko. The 5600 series movements were so successful that they eventually formed the base for the King Seiko and Grand Seiko lines of the era. The bold dials, faceted crystals, and angular cases of the 1970s Lord Matics perfectly encapsulate the daring and innovative spirit of Japanese watchmaking during that decade, making them highly sought after by modern collectors who appreciate both style and substance.
