A framed day-date window is positioned at three o'clock featuring a desirable English and Kanji day wheel. The defining feature of this timepiece is the original faceted mineral crystal which features distinct angled planes that refract light across the dial surface, creating a dynamic visual effect that is highly sought after by vintage Seiko enthusiasts. Case and Crystal The stainless steel case measures 36mm and follows the classic design language of the early 1970s with sharp lugs and a blend of brushed and polished surfaces. The case geometry remains well-preserved with defined edges that have not been over-polished. The faceted crystal is in remarkable condition for its age, allowing the unique geometry of the glass to be fully appreciated without the distraction of significant damage. The crown is recessed slightly into the case at the three o'clock position, maintaining the sleek profile of the watch. Movement Powering the watch is the reliable Seiko Caliber 5606 automatic movement.

The movement is clean and presents well, offering reliable vintage performance.

Remarks The Seiko Lord Matic "LM" series was positioned just below the King Seiko and Grand Seiko lines, offering high-end movement technology and superior finishing. This particular example, with its combination of a green gradient dial, gold accents, and the rare faceted crystal, represents the more adventurous and funky design ethos of the 1970s. It is a fantastic conversation piece that bridges the gap between dress watch elegance and retro flair. History Introduced in 1968, the Seiko Lord Matic line was essential in solidifying Seiko's reputation for manufacturing high-quality automatic watches for the upwardly mobile professional. The 5606 movement inside was a marvel of mass-production engineering, offering thinness and accuracy that rivaled Swiss competitors of the era. The Lord Matic series became a canvas for Seiko designers to experiment with bold dial colors and case shapes, leaving a legacy of some of the most attractive vintage watches available today. / Second Vintage SKU: SEI-SLD-0006
