Available now on auction by Second Vintage This Seiko Lord Matic is a vibrant exemplar of 1970s Japanese watchmaking, defined by its prismatic "Cut Glass" crystal and striking emerald hue. Positioned as a sophisticated mid-tier offering during Seiko's golden era, this Reference 5606-7360 combines geometric daring with high-grade mechanical performance. The faceted crystal acts as a kaleidoscope for the deep green sunburst dial, creating a dynamic interplay of light and shadow that changes with every movement of the wrist. Preserved in remarkable condition, this timepiece captures the essence of "funky" 1970s JDM design while maintaining the refined finish expected of the Lord Matic lineage. Brand: Seiko Model: Lord Matic Reference Number: 5606-7360 Serial Number: 4N9440 Movement: Automatic Caliber 5606A Dial: Emerald Green Sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1974 Condition: Excellent vintage condition, running and operational, offering reliable vintage performance (see timegrapher). Dial and Hands The dial presents a mesmerizing emerald green tone finished with a fine sunburst texture that radiates from the center. It is adorned with high-relief applied baton hour markers, each faceted to catch the light, and features a framed day-date window at the 3 o'clock position with a bilingual English and Kanji wheel. The applied "SEIKO" logo at 12 o'clock and the stylized "LM" emblem at 6 o'clock are crisp and metallic, floating above the "25 JEWELS" text. The handset consists of polished, flat-topped batons with central white inlays for legibility. The visual experience is dominated by the factory-original faceted mineral crystal, often referred to as "Cut Glass," which features a central flat plane surrounded by angled geometric facets, distorting and refracting the dial elements in a distinct vintage fashion. Case and Crystal The stainless steel case utilizes a "helmet" or cushion-style architecture that integrates seamlessly with the bracelet design. The upper surface of the bezel area exhibits a strong, factory-applied radial brushed finish, which transitions sharply into high-polish case sides. The lug profile is short and hooded, emphasizing the continuous flow of the metalwork. The case geometry remains sharp with well-defined edges, showing only honest signs of vintage wear. The faceted mineral crystal sits proud of the case, serving as the focal point of the watch's silhouette, and remains clear with the distinct geometric cuts well-preserved. Movement Driving the watch is the Seiko Caliber 5606A, a robust automatic movement featuring 25 jewels and Diashock protection. This specific caliber was a cornerstone of Seiko's engineering in the 1970s, offering a thinner profile and integrated automatic winding capabilities. The rotor is clearly signed, and the movement architecture is clean and utilitarian. Timegrapher results reflect current performance; the movement is running and shows very healthy results with a deviation of -5 to -15 seconds per day. Strap The watch is fitted with its original stainless steel link bracelet, authenticated by the "SEIKO LM" signed folding clasp. The bracelet features a five-link construction with a vertical brushed finish that matches the case top, tapering comfortably toward the clasp. It is currently sized to accommodate a wrist circumference of approximately 19cm. The links articulate smoothly, and the clasp closes securely, completing the authentic period aesthetic. Condition This vintage timepiece is in excellent condition, showcasing a vibrant and flawless dial that has resisted the effects of aging. The faceted crystal is remarkably clean, preserving the intended optical effects without significant obstruction. The stainless steel case retains its original factory finishes, with the radial brushing on the bezel remaining distinct and the polished sides showing only light handling marks. The movement is active and the day-date complication advances correctly. Dimensions The case measures 36 mm in diameter excluding the crown, a classic proportion that wears larger due to the cushion shape and the height of the faceted crystal. The lug-to-lug distance is compact, allowing for a balanced fit on a variety of wrist sizes, while the bracelet is sized for a wrist up to 19cm. Remarks The Lord Matic 5606-7360 is highly sought after by collectors for its specific combination of a colored "glam" dial and the elaborate faceted crystal. These "Cut Glass" models represent a specific design movement within Seiko during the mid-1970s, intended to bring a jewelry-like presence to the wrist. The emerald green variant is particularly desirable for its rich saturation and the way it highlights the prismatic effects of the glass. This example serves as both a reliable timekeeper and a stunning artifact of 1970s Japanese design culture. History Introduced in 1968, the Lord Matic (LM) series was developed to bridge the gap between Seiko's mass-market offerings and the prestigious Grand Seiko and King Seiko lines. Powered by the sophisticated 5600 series movements, the Lord Matic line became a playground for Seiko's designers to experiment with avant-garde case shapes, vibrant dials, and textured crystals throughout the 1970s. These watches played a pivotal role in establishing Seiko's reputation for combining mechanical reliability with daring aesthetics, leaving a legacy of designs that remain fresh and collectible decades later. / Second Vintage SKU: SEI-SAJ-0023
