Dial and Hands The dial is an absolute standout, featuring a rich emerald green tone with a distinct vertical gradient that transitions from a lighter, vertically brushed central band to darker, deeper green edges. This dynamic surface is adorned with applied silver-tone faceted baton indices, each detailed with precise black and white accents to enhance legibility. The applied Seiko and LM logos stand proud against the dial, complemented by crisp black printing for the automatic designation, jewel count, and the iconic Suwa factory symbol. A cleanly framed day-date aperture sits at three o'clock, showcasing a highly desirable dual-language Kanji and English day wheel. The faceted baton hands are perfectly matched to the indices, featuring central black stripes. Upon close visual inspection, the dial is in outstanding condition, remaining exceptionally clean and entirely free of moisture damage, spotting, staining, or print loss, presenting an immaculate and highly attractive face. Case and Crystal The 37 mm stainless steel case boasts a sharp, angular geometry quintessential to the era, featuring integrated lug profiles and flat planes that catch the light brilliantly. The transitions between the finely brushed upper surfaces and the highly polished case flanks remain well-defined and crisp, indicating careful wear over the decades. The watch is fitted with a spectacular, highly elevated faceted crystal that creates a kaleidoscope effect over the dial, adding immense depth and character. The crystal remains in very good condition, showing only minor, superficial micro-marks on the uppermost edges that do not detract from its striking appearance. The case exhibits honest, light handling marks and faint hairlines consistent with its age, completely avoiding the softened look of heavy polishing. The screw-down caseback is remarkably preserved, with all factory engravings, including the reference and serial numbers, remaining deep and fully legible. Movement Powering this timepiece is the esteemed Seiko Caliber 5606A, a 23-jewel automatic movement produced by the Suwa division. Close inspection of the movement reveals clean surfaces, a freely moving winding rotor prominently stamped with the Seiko branding and caliber details, and well-preserved mechanical components. Exhibiting remarkable accuracy and consistency, it performs brilliantly for a vintage timepiece. Timegrapher results show +8 to +10 seconds per day with strong amplitude. The movement has been serviced on 6/25/2026 and performs strongly. Strap The watch is presented on its original stainless steel block-link bracelet, a crucial detail for collectors seeking completeness. The folding clasp is proudly stamped with both the Seiko and LM logos in crisp relief. The bracelet exhibits normal, age-appropriate stretch and light surface wear, draping comfortably on the wrist and accommodating a size of up to 18 cm. Condition This timepiece is presented in excellent vintage condition. It has been wonderfully preserved, retaining its sharp factory case lines, its dramatic faceted crystal, and a genuinely flawless dial that remains free of any detrimental aging. The original branded bracelet completes the package, while the minor surface hairlines across the polished flanks are entirely consistent with careful, appreciative ownership over the past fifty years. Dimensions The case measures 37 mm in width, excluding the crown. The included original stainless steel bracelet is sized to accommodate a wrist of up to 18 cm. Remarks Finding a Lord Matic with its original faceted crystal intact and a colored gradient dial in such pristine condition is a rare treat for vintage enthusiasts. The interplay between the cut glass and the emerald green surface makes this watch incredibly dynamic in natural light. It is a superb acquisition for anyone looking to add a vibrant, structurally fascinating, and mechanically robust piece of Japanese horological history to their collection. History Introduced in 1968, the Seiko Lord Matic line was positioned perfectly in the upper-mid tier of Seiko's catalog, serving as the sophisticated bridge between the standard automatic models and the elite King Seiko and Grand Seiko ranges. Powered by the sophisticated 56-series calibers, the Lord Matic became a canvas for Seiko's most daring and fashionable designs in the 1970s. Models featuring colored gradient dials and cut-glass faceted crystals were highly prized in the Japanese domestic market, reflecting a period of immense optimism and stylistic freedom. Today, these expressive variants are celebrated by collectors for their unmistakable retro-futuristic charm and enduring mechanical quality.
