Presented for auction by Second Vintage This Seiko Lord Matic reference 5606-7191 is a captivating example of 1970s Japanese horology, distinguished by its rare and vibrant emerald green sunburst dial. The Lord Matic line was positioned directly beneath King Seiko, offering high-grade movements and sophisticated finishing. This specific example features the clean, smooth crystal variation rather than the faceted glass often found on these models, allowing for an unobstructed view of the dynamic dial which shifts from deep forest green to bright teal under different lighting.

The dial is furnished with applied silver baton indices featuring white contrast inlays, matched by slender polished hands. A framed day-date window is positioned at 3 o'clock, featuring both Kanji and English day options. The applied silver 'Seiko' and 'LM' logos remain crisp and bright, and the dial surface appears remarkably clean and well-preserved. Case and Crystal The stainless steel case measures 36 mm and exhibits the classic sharp lines characteristic of Seiko's "Grammar of Design" influence from this era. The surfaces show a blend of polished and brushed finishes, preserved in very good condition with only minor handling marks consistent with its age. Notably, this model is fitted with a flat crystal, providing excellent legibility and a sleek profile. The caseback engravings, including the reference and serial numbers, remain deep and clearly legible. Movement Powered by the robust Seiko Caliber 5606 automatic movement, this 23-jewel mechanism is known for its durability and engineering quality, serving as a base for higher-end King Seiko models of the era. The movement is clean and is currently running within vintage tolerances, offering reliable vintage performance. Strap The watch is paired with a vintage-style brown leather strap featuring an alligator grain pattern and matching stitching. The strap is secured by a silver-tone pin buckle, and the rich brown leather complements the green dial tones perfectly, offering a sophisticated dress-watch aesthetic. Condition This timepiece is in excellent vintage condition. The dial is exceptionally clean, retaining its original vibrancy without visible spotting or aging. The case retains strong definition with no significant dents or heavy damage, showing only light surface wear appropriate for a watch from 1973. The crystal is clear and free of distracting scratches. Dimensions The case measures 36 mm in diameter excluding the crown, offering a classic vintage fit. The lug width is 18 mm, allowing for easy strap changes if desired. Remarks The green dial variant of the 5606-7191 is significantly harder to find than the standard white, silver, or black versions, making this a desirable piece for collectors. The combination of the '70s green aesthetic with the clean, unfaceted crystal makes for a highly wearable and stylish vintage daily driver that captures the essence of the era. History Introduced in 1968, the Lord Matic series was a core part of Seiko's lineup, utilizing the 56xx series of movements which were also used as the base for King Seiko and Grand Seiko chronometers of the time. The line represented a perfect middle ground of luxury and practicality, often featuring sophisticated case designs and high-quality automatic movements that helped cement Seiko's reputation for mechanical excellence during the 1970s.
