Seiko - Lord Matic 銀波 (Ginpa) – Silver Wave - No reserve price - 5606-7070 - Men - 1970

Available now on auction by Second Vintage This Seiko Lord Matic represents a significant chapter in the history of Japanese horology, offering a blend of sophisticated design and robust engineering that defined Seiko's rise in the late 1960s and early 1970s. Positioned just below the Grand Seiko and King Seiko lines, the Lord Matic series was designed for the aspiring professional, featuring high-grade automatic movements and sharp, grammar-of-design case lines. This specific example features the desirable front-loading monocoque case design, ensuring better water resistance and a slimmer profile, making it an exceptional choice for collectors seeking a versatile and historically significant dress watch. Brand: Seiko Model: Lord Matic Reference Number: 5606-7070 Serial Number: 0N2800 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 shows honest signs of wear consistent with its age, particularly on the case, while the dial remains in attractive condition. Timegrapher results indicate the movement is running between -10 and -14 seconds per day, which indicates healthy movement performance. Dial and Hands The silver sunburst dial is the highlight of this timepiece, presenting a clean and sophisticated aesthetic that catches the light beautifully. It features applied silver baton indices with black inlays, matching the slender handset for excellent legibility. The applied "Seiko" and "LM" logos are crisp and raised, adding depth to the face. A framed day-date window is positioned at 3 o'clock. The dial shows very minimal aging, retaining a bright and fresh appearance that defies its production year. Case and Crystal The stainless steel case features the clever "Open Thru Glass" monocoque construction, meaning the movement is accessed from the front to minimize entry points for moisture. The case flanks and bezel show visible scratches and marks typical of a watch that has been enjoyed over several decades, though the distinctive case geometry remains intact. The caseback features the period-correct "Water Proof" text, a detail that was phased out shortly after this watch was produced in favor of "Water Resistant," adding a layer of collectibility. The crystal exhibits some surface marks and hazing consistent with vintage wear. Movement Powering this Lord Matic is the highly regarding Seiko Caliber 5606, a 23-jewel automatic movement known for its reliability and slim profile. This movement was a workhorse of the era, offering hacking capabilities and a day-date complication. The watch is currently functioning well, with timegrapher readings showing a rate of -10 to -14 seconds per day, offering reliable vintage performance. Strap The watch is fitted with a black leather strap featuring contrasting white stitching and an embossed texture. The strap is in very good condition and complements the monochrome aesthetic of the silver dial and steel case, making the watch ready for immediate wear. Condition This timepiece is in good vintage condition. While the case shows evident surface scratches and wear from decades of use, the structural integrity remains strong. The dial is well-preserved, serving as a bright focal point against the patina of the steel case. The movement is mechanically sound based on the provided timegrapher data. Dimensions With a case diameter of 36 mm excluding the crown, the watch sits comfortably on the wrist in a classic vintage proportion. The monocoque case design allows for a relatively slim profile, allowing it to slide easily under a shirt cuff while retaining enough presence for casual wear. Remarks This specific example dates to November 1970, placing it right at the transition period for Seiko's caseback nomenclature. Finding a "Water Proof" stamped 5606-7070 is becoming increasingly difficult as collectors snap up these transitional pieces. The combination of the monocoque case, the robust 5606 movement, and the clean sunburst dial makes this a quintessential example of Seiko's mid-century design philosophy. History Introduced in 1968, the Lord Matic (LM) line was Seiko's mid-tier offering, sitting essentially as the daily wearer for the successful salaryman, just beneath the King Seiko. The 5606 movement used in these watches became legendary for its accuracy and durability, serving as the base for many higher-end Seiko movements. The Lord Matic series played a crucial role in establishing Seiko's dominance in the automatic watch market of the 1970s, offering high style and high performance at an accessible luxury price point. / Second Vintage SKU: SEI-SLJ-0038
