Now available at auction from Second Vintage This Seiko Lord Matic from 1973 is a captivating example of Japanese watchmaking design from the golden era of the 1970s. With its distinctive amber-gold gradient dial and sharp case architecture, this timepiece embodies the "Grammar of Design" philosophy while offering a unique aesthetic that changes character depending on the lighting. The Lord Matic line was positioned as a high-grade automatic series, sitting just beneath King Seiko, and this reference 5606-7300 captures the essence of that prestigious lineage. Brand: Seiko Model: Lord Matic Reference Number: 5606-7300 Serial Number: 382273 Movement: Automatic Caliber 5606A Dial: Amber Gradient Sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Good vintage condition. The watch shows honest signs of wear and age throughout the case and crystal, presenting as a genuine, unpolished vintage example. Dial and Hands The dial is the standout feature of this timepiece, presenting a rich amber to dark brown gradient sunburst finish that radiates from the center. It features applied gold-tone hour markers with white detail, offering excellent contrast against the warm background. The gold-tone hands coordinate perfectly with the indices. A framed day-date window is positioned at 3 o'clock, displaying a bilingual English and Kanji day wheel, a desirable feature for collectors of JDM (Japanese Domestic Market) timepieces. The dial retains the applied "LM" logo and "25 Jewels" text in crisp condition. Case and Crystal The stainless steel case measures 36mm and follows a classic 1970s silhouette with integrated lugs and sharp angles. The case surfaces show visible scratches and handling marks commensurate with its age and honest usage. The faceted crystal, a signature element of specific Lord Matic references, creates unique light reflections but does show noticeable scratches and surface wear upon close inspection. The caseback is clearly engraved with the reference and serial numbers, remaining legible. Movement Powering the watch is the reliable Seiko Caliber 5606A, a 25-jewel automatic movement known for its robust engineering. The movement is clean and features the signed Seiko rotor. Timegrapher testing indicates the movement is running with a deviation of -41 to -47 seconds per day, indicating the movement is functioning within an acceptable operational range for an unrestored vintage mechanism. Strap The watch is fitted with a period-correct vintage stainless steel bracelet that complements the case design perfectly. The bracelet is substantial and articulates well, securing firmly to the wrist. It is currently sized to fit a wrist circumference of approximately 18.5 cm. Condition This timepiece is in good vintage condition. It has been preserved in an honest state, showing visible wear to the metalwork and crystal that tells the story of its fifty-year history. The dial remains attractive despite the external wear, and the movement is operational. Dimensions With a diameter of 36mm, the watch offers a classic mid-size profile that sits comfortably on the wrist. The lug-to-lug length and case thickness ensure it slides easily under a cuff while maintaining a presence typical of 1970s design languages. Remarks This Seiko Lord Matic 5606-7300 is a characterful representative of 1970s style, combining a stunning gradient dial with a robust automatic movement. It is a piece that appeals to collectors who appreciate the unique Japanese design ethos of the era.
