Born from the prestigious **Daini Seikosha** factory under reference **4402-8000**, this second-generation King Seiko was engineered specifically as an uncompromising rival to Suwa's Grand Seiko line, capturing the supreme corporate ambition and horological pride of the era.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Over-Engineered 25-Jewel Caliber 4402 Manual Heart:\u003c\/b\u003e Powering this historic timepiece is the legendary **25-jewel Caliber 4402A**, a robust in-house manual-wind engine operating at a classic frequency of **18,000 vibrations per hour (vph)**. Celebrated by vintage purists as one of Daini's most durable manual movements, it deploys a lavish **25-jewel specification** to control gear-train friction. It incorporates an advanced **hacking seconds mechanism** (stop-second function) alongside an integrated quick-set date configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"8000\"\" Grammar of Design Case Mastery:\u003c\/b\u003e The reference **4402-8000** is globally revered among serious collectors as a foundational textbook implementation of Taro Tanaka's **\"\"Grammar of Design\"\"** guidelines. The solid stainless steel case features extraordinarily bold, razor-sharp facets and muscular, flat-surfaced lugs finished with zero-distortion mirror polishing. This geometric architecture allowed the mechanical instrument to sit completely flat and authoritative against the wrist.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eImmaculate Calendar Dial Harmony and Crisp Legibility:\u003c\/b\u003e The dial of the **4402-8000** is a study in clinical mid-century visual balance, showcasing a brilliant silver sunburst canvas. It features **hand-applied, multifaceted rectangular block indices** with a prominent double index at 12 o'clock and razor-sharp dauphine hands that capture light with striking contrast. Framed neatly at 3 o'clock, the quick-set date window provides instant split-second legibility, proudly signed with the applied **\"\"SEIKO\"\"** logo and Daini lightning bolt emblem above 6 o'clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Gold Shield Medallion of Kameido's Heritage:\u003c\/b\u003e The ultimate hallmark of this 1966 treasure sits proudly on the screw-down case back: a **pristine, solid gold-embossed King Seiko shield medallion**. Featuring the iconic cross-hilted sword and crown crest, this emblem historically certified its factory-regulated precision and elite manufacturing standard. Built to an uncompromising heirloom quality, the 4402-8000 stands as an eternal, investment-grade cornerstone reference for collectors worldwide.\u003c\/li\u003e\n\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003cdl style=\"margin:0 0 34px 40px\"\u003e\n\u003cdt style=\"font-size: 24px;font-weight: bolder;\"\u003eFor more information, please look at the pictures.\u003c\/dt\u003e\n\u003cdd\u003e\u003cdiv style=\"margin: 14px 0 40px 0;\"\u003e\u003cimg src=\"https:\/\/nonkun.boy.jp\/img_ebay\/h1235818600.jpg\"\u003e\u003c\/div\u003e\u003c\/dd\u003e\n\u003cdt style=\"font-size: 24px;font-weight: bolder;\"\u003eNotes\u003c\/dt\u003e\n\u003cdd\u003e\n\u003cul style=\"margin-bottom: 18px;\"\u003e\n\u003cli\u003e\n\u003cb\u003eBefore buying.\u003c\/b\u003e\u003cdiv style=\"padding-left : 30px;\"\u003eThe vintage watches we sell are inspected and adjusted so they work fine.
