Available now on auction by Second Vintage This Seiko Lord Matic represents a distinct era of Japanese watchmaking, combining the sharp "Grammar of Design" case lines with the robust engineering that defined Seiko's rise to global prominence in the late 1960s and early 1970s. With its clever monocoque front-loading case design and a pristine silver sunburst dial, this reference 5606-7000 is a wonderful example of why the LM series remains a favorite among collectors who appreciate value and style. Brand: Seiko Model: Lord Matic Reference Number: 5606-7000 Serial Number: 053371 Movement: Automatic Caliber 5606 Dial: Silver sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Good vintage condition. The watch presents an honest aesthetic with visible wear to the case consistent with its age, while the dial remains in exceptional condition. Dial and Hands The silver sunburst dial is the highlight of this timepiece, preserved in excellent condition with a bright and clean finish. It features applied silver baton indices with black inlays that match the handset perfectly. The applied "SEIKO" and "LM" logos are crisp and raised, adding depth to the face. A framed day-date window sits at the 3 o'clock position, displaying both English and Kanji days, a desirable feature for collectors. The dial is signed with the Suwa Seikosha whirlpool logo above 6 o'clock. Case and Crystal The stainless steel case features the unique "Open Thru Glass" monocoque construction, meaning the movement is accessed from the front to improve water resistance and structural integrity. The case retains its distinctive shape with angled lugs, though it shows visible surface scratches, marks, and signs of use throughout, typical of a watch enjoyed over several decades. The caseback engravings are deep and fully legible, proudly displaying the "Waterproof" designation which helps confirm its early 1970 production date. The crystal is clean and presents well. Movement Powering the watch is the reliable Seiko Caliber 5606 automatic movement, featuring 23 jewels. This movement is renowned for its durability and was a higher-end caliber for the domestic market at the time. Timegrapher testing shows the watch running between +10 and +17 seconds per day, which indicates a healthy movement performing well within vintage tolerances. Strap The watch is fitted with a unique black leather strap featuring an embossed scale-like texture with subtle iridescent green and purple highlights. The strap is finished with white contrast stitching and a stainless steel buckle, giving the watch a distinct and sporty personality on the wrist. Condition This timepiece is in good vintage condition. While the case shows clear evidence of its history through surface wear and scratches, the dial is remarkably well-preserved, creating a pleasing contrast between the honest exterior and the fresh face. Dimensions The case measures 36 mm in diameter excluding the crown, offering a classic vintage fit that slides easily under a cuff while maintaining presence on the wrist. Remarks This Lord Matic is a charming example of Seiko's golden era, featuring the desirable "Waterproof" caseback text that was phased out shortly after this watch was produced. It is a stylish daily wearer that combines historical significance with reliable mechanical performance. History The Lord Matic line was introduced by Seiko in 1968 as a mid-tier offering, positioned just below the Grand Seiko and King Seiko lines but above the standard automatic models. It utilized the high-grade 5606 movement, which brought hacking and hand-winding capabilities to a wider audience. The LM series played a crucial role in establishing Seiko's reputation for accuracy and avant-garde design during the 1970s.
