Brand: Seiko Model: Lord Matic Reference Number: 5606-7360 Serial Number: 404633 Movement: Automatic Caliber 5606A, 25 Jewels Dial: Emerald green sunburst with faceted applied indices, exceptionally clean and well-preserved Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1974 Condition: Excellent vintage condition with a pristine dial and sharp case lines Dial and Hands The dial is an absolute visual delight, featuring a rich emerald green tone that radiates with a vibrant sunburst finish. Depending on the lighting, the color shifts dynamically from a deep forest green to a brilliant jewel tone. The dial furniture is beautifully executed, featuring tall, faceted applied silver-tone indices with crisp white central channels that perfectly match the sleek baton hands. The applied "SEIKO" and "LM" logos add a premium sense of depth, while the printed "AUTOMATIC" text and the Suwa factory symbol remain perfectly crisp. A framed day-date aperture sits cleanly at the three o'clock position, displaying a vibrant red Sunday indicator. Crucially, the dial is in stunning, near-mint condition, showing no visible spots, staining, moisture marks, or edge degradation, making it a premium example for discerning collectors. Case and Crystal The 36mm stainless steel case features a classic 1970s tonneau profile, characterized by its hooded lugs and seamless flow into the bracelet. The case retains excellent definition, showcasing crisp vertical brushing across the upper surfaces that contrasts beautifully with the brightly polished case flanks. Honest, light handling marks and micro-scratches are present, entirely consistent with careful vintage wear, but the case remains thick and well-preserved without any signs of heavy over-polishing. The watch is fitted with a spectacular, highly elevated faceted crystal, cut with intersecting geometric planes that create a kaleidoscopic effect over the green dial. The crystal is clear and intact, showing only very minor superficial surface wear that does not detract from its impressive visual impact. The screw-down caseback is sharply engraved with the reference, serial number, and Seiko branding. Movement Powering this timepiece is the esteemed Seiko Caliber 5606A, a 25-jewel automatic movement that was a workhorse of the Lord Matic family. Visual inspection of the movement reveals a clean, well-maintained mechanism with bright rhodium-plated surfaces and a cleanly signed rotor bearing the "SEIKO", "25 JEWELS", and "JAPAN 5606A" engravings. The gears and bridges present beautifully, showing no signs of heavy oxidation or moisture intrusion. The caliber represents Seiko's commitment to robust, high-performing automatic movements during this highly competitive era of watchmaking. Strap The watch is presented on its original period-correct stainless steel flat-link bracelet. The bracelet integrates perfectly with the hooded lugs of the tonneau case, maintaining the uninterrupted sleekness of the 1970s design. The folding clasp is proudly stamped with the raised "SEIKO LM" branding, confirming its authenticity. The bracelet shows moderate, age-appropriate wear and stretch, retaining a comfortable and fluid drape on the wrist. Condition This timepiece is in excellent vintage condition. The case retains strong factory lines and attractive alternating finishes, with only normal, light signs of previous enjoyment. The star of the show, the brilliant green dial, is exceptionally preserved and free of any notable flaws or discoloration. The original faceted crystal elevates the entire presentation, and the matching signed LM bracelet completes a highly collectible package. Dimensions The stainless steel case measures 36 mm in diameter excluding the crown. The integrated-style bracelet is sized to accommodate a wrist up to 18 cm comfortably. Remarks Vibrant colored dials paired with faceted crystals are among the most highly sought-after configurations in the vintage Seiko collecting community. This Lord Matic captures the absolute essence of that flamboyant 1970s aesthetic while remaining an incredibly wearable and reliable daily vintage companion. The preservation of the dial and the presence of the signed bracelet make this a particularly compelling acquisition. History Introduced in the late 1960s, the Seiko Lord Matic (LM) series was an integral part of Seiko's catalog, aimed at the ambitious middle-class professional. Manufactured primarily by the Suwa Seikosha factory, the LM line utilized the advanced 56-series automatic calibers, which were thin, reliable, and capable of high precision. The Lord Matic shared much of its mechanical DNA with the higher-tier King Seiko models of the same era, offering exceptional value and an incredible variety of case shapes, dial textures, and crystal designs that have cemented its legacy as a favorite among vintage enthusiasts. / Second Vintage SKU: SEI-SLJ-0131
