Key Features

• The Sovereign Peak of 1973 Executive Luxury (1973): Manufactured in 1973—a landmark historical year during Japan's mature post-war economic boom and peak mechanical dominance—the Seiko Lord Matic Weekdater reference 5606-7071 represented Suwa Seikosha's quintessential business-class flagship. Positioned directly beneath the King Seiko lineup, this refined reference provided corporate leaders with near-chronometer-grade mechanical performance wrapped in timeless Showa-era dress styling.
• The Over-Engineered 23-Jewel Caliber 5606 Automatic Heart: Powering this historic instrument is the revered 23-jewel Caliber 5606, an in-house automatic engine operating at a smooth frequency of 21,600 vibrations per hour (vph). Highly respected by vintage purists for its remarkably thin profile and long-term daily stability, this movement deploys a 23-jewel specification to minimize gear-train friction, complete with hacking seconds, quick-set dual calendar control, and smooth manual-winding capability.
• Architectural ""7071"" Grammar of Design Case Geometry: The reference 5606-7071 is globally distinguished among vintage Seiko collectors as an evolved, high-precision execution of Taro Tanaka's ""Grammar of Design"" guidelines. Executed in solid stainless steel, the case features razor-sharp angular facets, broad sweeping lugs, and zero-distortion mirror-polished Zaratsu planes that capture light with extreme contrast while resting completely flat against the wrist.
• Masterful ""Weekdater"" Dial Harmony and Bilingual Utility: The dial of the 5606-7071 showcases exemplary mid-1970s visual balance, featuring a radiant silver sunburst canvas set with hand-applied, multifaceted rectangular block indices and razor-sharp hands. Symmetrically framed at 3 o'clock, the dual-calendar window houses a bilingual (English/Kanji) day disk alongside a quick-set date wheel, offset by the applied polished ""LM"" emblem above 6 o'clock.
• An Investment-Grade Masterpiece of Suwa's Automatic Heritage: Manufactured in the milestone mechanical year of 1973, the 5606-7071 23-jewel Lord Matic Weekdater remains a highly sought-after, universally respected cornerstone reference for serious vintage Seiko collectors worldwide. Capturing the precise era where Suwa Seikosha perfected ultra-thin, high-utility automatic daily instruments right before the global industry shifted toward digital quartz technology, it stands as an eternal testament to 1970s Japanese horological design.
