Produced by the **Suwa Seikosha** factory during a golden era of fierce industrial pride, this legendary timepiece was regulated to an elite, near-chronometer standard. It was engineered specifically to project power, prestige, and executive success for top-tier Japanese business leaders during the soaring mid-Showa economic boom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Grand-Tier 35-Jewel Caliber 6218 Masterpiece:\u003c\/b\u003e This watch is powered by the magnificent **35-jewel Caliber 6218** (specifically Cal. 6218A\/B), a highly sophisticated automatic movement operating at **18,000 vibrations per hour (vph)**. In **1965**, a **35-jewel count** was a spectacular over-engineering statement, utilizing an incredible number of synthetic rubies to eliminate friction within the gear and calendar trains. Featuring a high-end **tadpole micro-regulator (fine adjustment lever)** and Seiko’s famous **Magic Lever** system, this caliber directly served as the mechanical architecture for the first-ever Automatic Grand Seiko (62GS).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"8950\"\" Muscular Executive Case Geometry:\u003c\/b\u003e The reference **6218-8950** is celebrated globally for its commanding, heavy-set case presence. The stainless steel case features extraordinarily thick, broad lugs and an expansive bezel profile that perfectly previews Taro Tanaka's foundational **\"\"Grammar of Design.\"\"** Complete with the signature **crown entirely recessed at 4 o'clock** to signal that manual winding was visually obsolete, this robust geometry maximized wrist presence while slipping perfectly under a tailored tailored sleeve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFlawless \"\"Weekdater\"\" Dial Purity and Symmetry:\u003c\/b\u003e The dial of the **6218-8950** is a masterclass in mid-century clinical clarity, showcasing a radiant silver sunburst finish and **hand-applied, multifaceted chunky block indices** with black contrast tracks. The dual-calendar layout provides immense visual authority: a framed date aperture at 3 o'clock and a distinctively large, **independent arched day window sitting proudly at 6 o'clock**. This immaculate layout ensured split-second legibility for high-stakes corporate negotiation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Golden Lion Legacy:\u003c\/b\u003e Produced in the historic milestone year of **1965**, the 6218-8950 remains an absolute \"\"holy grail\"\" cornerstone for purist vintage Seiko collectors worldwide. It represents the crucial historical peak before Grand Seiko absorbed Seiko's ultimate automatic output. Most famously adorned with the prestigious **solid gold Lion Medallion** on the case back—the universal mid-century symbol reserved solely for Seiko's highest-grade luxury achievements—it stands as a profound testament to an era of uncompromised micro-engineering.\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\/l1231024666.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.
