The reference **4402-8000** was produced during a landmark year when Seiko's internal competition led to world-leading precision. Positioned as a luxury instrument of clinical accuracy, it was the definitive choice for the elite Japanese professional who demanded a watch that could rival the finest Swiss chronometers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Robust 25-Jewel Caliber 4402:\u003c\/b\u003e This watch is powered by the **25-jewel Caliber 4402A**, a heavy-duty manual-wind movement operating at **18,000 vibrations per hour (vph)**. In **1967**, the 44-series was celebrated for its oversized balance wheel and high-torque mainspring, ensuring exceptional stability. Unlike the earlier 44KS models, the **4402 introduced a date complication with a quick-set function**, making it a highly practical tool for the modern, fast-paced business environment of the late 60s.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMastery of the \"\"Grammar of Design\"\" Geometry:\u003c\/b\u003e The reference **4402-8000** is a textbook example of Taro Tanaka’s design revolution. The case features **thick, powerful lugs** with broad, mirror-polished facets created using the legendary **Zaratsu (blade) polishing** technique. In **1967**, this architectural rigor was intended to make the watch \"\"sparkle\"\" with masculine elegance, establishing the visual DNA that still defines the modern Grand Seiko \"\"Heritage\"\" collection today.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Prestige of the Gold \"\"KS\"\" Shield Medallion:\u003c\/b\u003e A defining hallmark of the **1967** 4402-8000 is the **solid gold \"\"KS Shield\"\" medallion** inset into the stainless steel case back. This was the ultimate seal of high-grade craftsmanship, marking the watch as a masterpiece of Daini Seikosha. The dial, featuring a radiant sunburst silver finish and **hand-applied, multifaceted baton indices**, prioritized extreme legibility and a sophisticated, understated luxury that commanded respect in any boardroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA Landmark of Showa-Era Horological Art:\u003c\/b\u003e Produced in **1967**, the 4402-8000 remains one of the most significant \"\"Grail\"\" watches for vintage collectors worldwide. It represents the \"\"Purest Era\"\" of King Seiko, combining **heavy-duty mechanical engineering with timeless Japanese aesthetics**. It stands as a testament to the era when Daini Seikosha perfected the manual-wind movement, creating an enduring icon that remains as accurate and visually stunning today as it was over half a century ago.\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\/b1223117714.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.
