Available now on auction by Second Vintage This Seiko Lord Matic represents the golden era of Japanese watchmaking from the 1970s, offering a perfect blend of sophisticated design and robust mechanical engineering.

This specific example features a pristine silver sunburst dial and the highly regarded 5606 movement, making it a compelling choice for collectors valuing condition and classic 1970s aesthetics. Brand: Seiko Model: Lord Matic LM Reference Number: 5606-8031 Serial Number: 519160 Movement: Automatic Caliber 5606A Dial: Silver Sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1975 Condition: Excellent vintage condition. The watch presents with a remarkably clean dial and a sharp case that retains its original geometry. Timegrapher results indicate the movement is running between +11 and +15 seconds per day, which indicates a healthy movement. Please notice that the crown is pulled out in the images, but everything functions as intended. Dial and Hands The silver sunburst dial is in exceptional condition, free from significant aging or spotting which is rare for this vintage. It features applied baton hour markers with black central inlays that match the handset, creating high legibility and a sharp contrast against the silver background. The applied "SEIKO" and "LM" logos are crisp and raised. A framed day-date window is positioned at 3 o'clock, displaying the day in English and red text for Sunday. The distinct Suwa Seikosha logo is printed clearly above the 6 o'clock marker. Case and Crystal The stainless steel case features the distinct architectural styling typical of 1970s Seiko design, with brushed upper surfaces on the lugs and polished sides. The case edges remain defined, suggesting the watch has been treated with care over the decades. The crystal is clear and allows for an unobstructed view of the dial. The screw-down caseback is clearly engraved with the reference number, serial number, and "Water Resist-G" markings, all of which are legible and deep. Movement Powering this timepiece is the Seiko Caliber 5606A, a 25-jewel automatic movement that was a staple of high-grade mid-tier Seikos of the era. The movement presents cleanly in the photographs and offers reliable vintage performance. Based on the provided timegrapher data, the watch is running between +11 and +15 seconds per day, which is a strong result for a vintage mechanical timepiece of this age. Strap The watch is fitted with a black leather strap featuring contrasting white stitching. The strap is in very good condition and complements the monochrome aesthetic of the silver dial and steel case, secured by a silver-tone pin buckle. Condition This timepiece is in excellent vintage condition. The case shows only minor surface handling marks consistent with careful use, while the dial remains virtually flawless. The movement is clean and operating within acceptable vintage parameters as evidenced by the timegrapher reading. The overall presentation is that of a well-preserved collector's piece. Dimensions With a case diameter of 36 mm, this watch sits comfortably on the wrist in a classic mid-size proportion. The lug design allows for a balanced presence that works well for both formal and casual wear. Remarks The Seiko Lord Matic 5606-8031 is a testament to the enduring quality of Seiko's 1970s production. Finding examples with such clean dials and well-preserved cases is becoming increasingly difficult. This watch offers the distinct "Grammar of Design" influence found in higher-end Seikos at a more accessible point, making it a smart acquisition for vintage enthusiasts. History Introduced in the late 1960s, the Lord Matic (LM) line was essential in solidifying Seiko's dominance in the automatic watch market. The 5606 movement inside was an upgrade from previous generations, offering a thinner profile and integrated automatic winding. These watches were often gifted for long service awards or corporate milestones in Japan, earning them a reputation for reliability and class. Produced in January 1975, this specific watch captures the essence of that era perfectly. / Second Vintage SKU: SEI-SLJ-0100
