Produced during the peak of Tanaka’s "Grammar of Design" influence, this timepiece features the desirable monocoque front-loading case structure and remains in spectacular preservation. It offers a unique opportunity to acquire a piece of horological history that sits comfortably between the standard lineup and the prestigious Grand Seiko models of its time. Brand: Seiko Model: Lord Matic Reference Number: 5606-7000 Serial Number: 057477 Movement: Automatic Caliber 5606 Dial: Silver Sunburst Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Near-mint vintage condition. Timegrapher reading indicates +17 to +22 seconds per day, which indicates healthy movement operation. Dial and Hands The silver sunburst dial is preserved in flawless condition, showcasing a radiant finish that catches the light beautifully. It features polished applied baton indices with black central inlays that match the slender handset, ensuring high legibility and a sharp aesthetic. The applied "Seiko" and "LM" logos are crisp and raised, adding depth to the face. A framed day-date window is positioned at three o'clock, and the dial is signed with the Suwa Seikosha hourglass symbol, denoting its high-quality origin. Case and Crystal The stainless steel case is a standout feature of this reference, utilizing a "monocoque" or one-piece construction where the movement is accessed through the crystal, increasing water and dust protection. The case geometry is incredibly sharp, retaining its original factory brushing on the upper surfaces and high-polish finishing on the sides. The lugs display crisp, defined edges that suggest the watch has seen minimal use and likely remains unpolished. The crystal is clear and free of distracting marks, maintaining the watch's pristine profile. Movement Powering this timepiece is the reliable Seiko Caliber 5606, a sophisticated 23-jewel automatic movement that was a staple of the Lord Matic line. This movement offers both hand-winding and hacking capabilities, features that were advanced for the era. The movement is running efficiently within acceptable vintage tolerances, backed by the timegrapher results provided in the listing description. Strap The watch is fitted with a new black leather strap featuring an alligator-style grain pattern. It complements the dressy nature of the Lord Matic perfectly and is secured with a silver-tone buckle, making it ready for immediate wear. Condition This timepiece is in near-mint vintage condition, which is rare for a model of this age. The specific "Waterproof" stamping on the caseback confirms its early production status before the industry switch to "Water Resistant." The dial shows no signs of aging, spotting, or patina degradation. The case retains its architectural integrity with only the faintest handling marks visible upon close inspection, presenting as a highly collectible example. Dimensions With a case diameter of 35mm, the watch wears classically on the wrist, offering a refined presence that slides easily under a dress cuff. The distinct lug shape and one-piece case design give it a slightly more substantial feel than typical dress watches of the period. Remarks This reference 5606-7000 is often cited as one of the purest expressions of late 1960s Seiko design. Finding a "Waterproof" stamped monocoque example in this state of preservation is becoming increasingly difficult for collectors. It combines historical significance, robust mechanical engineering, and elegant styling in a package that has appreciated steadily in the vintage market. History Introduced in 1968, the Lord Matic (LM) line was positioned just below the King Seiko and Grand Seiko models, offering high-grade movements and superior case finishing to the aspiring professional market. The LM series played a pivotal role in solidifying Seiko's reputation for automated manufacturing precision. The 5606 movement inside this watch was so successful that it served as the base for many higher-end chronometer-grade movements in the years that followed.
