Key Features

• The Sovereign Dawn of the Iconic Lord Matic Series (1968): Manufactured in 1968—a pivotal historical year during Japan's mid-Showa industrial boom—the Seiko Lord Matic Weekdater reference 5606-7040 represents an essential early cornerstone of the celebrated Lord Matic lineage. Born from the prestigious Suwa Seikosha factory, this first-year 56LM model debuted to offer corporate executives high-grade mechanical performance wrapped in sleek, forward-looking dress architecture.
• The Over-Engineered 23-Jewel Caliber 5606 Automatic Heart: Powering this historic timepiece is the revered 23-jewel Caliber 5606, an in-house automatic engine operating at a smooth frequency of 21,600 vibrations per hour (vph). Celebrated by vintage purists for its remarkably thin profile and daily rate stability, this movement deploys a 23-jewel specification to minimize gear-train friction, complete with hacking seconds, quick-set dual calendar control, and manual-winding capability.
• Architectural ""7040"" Capped Lugs and Grammar of Design Geometry: The reference 5606-7040 is globally distinguished among vintage Seiko collectors for its unique case architecture featuring prominent, broad-capped lugs. Executed in solid stainless steel, the case incorporates razor-sharp angular facets and zero-distortion mirror-polished Zaratsu planes inspired by Taro Tanaka's ""Grammar of Design"" guidelines, allowing it to sit completely flat against the wrist.
• Masterful ""Weekdater"" Dial Harmony and Bilingual Utility: The dial of the 5606-7040 showcases exemplary late-1960s visual balance, featuring a radiant silver sunburst canvas decorated with hand-applied, multifaceted rectangular block indices and 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 during the introductory release year of 1968, the 5606-7040 23-jewel Lord Matic Weekdater remains a highly sought-after, universally respected cornerstone reference for serious vintage Seiko collectors. Capturing the precise historical moment where Suwa Seikosha revolutionized ultra-thin automatic watchmaking, it stands as an eternal heirloom of Japanese horological history.
