Sourced in the pre-1964 numbering era, this Suwa Seikosha flagship introduced the world's very first automatic movement featuring a full day-of-the-week spelled out in an arched aperture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Ultra-High Jewel 33-Jewel Caliber 400 Automatic Engine:\u003c\/b\u003e Powering this historic treasure is the legendary **33-jewel Caliber 400** (later designated as the 6218 caliber family), operating at a steady frequency of **18,000 vibrations per hour (vph)**. Equipping an automatic watch in **1963** with a monumental **33-jewel count** represented the pinnacle of mechanical luxury engineering, scattering synthetic rubies across gear-train pivots and winding components to virtually eliminate wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"J13080\"\" Heavy Case Geometry and Recessed Crown:\u003c\/b\u003e Sourced in a robust, heavy-gauge stainless steel case, the reference **J13080** features bold, sweeping lugs with thick polished chamfers.

It proudly showcases the iconic **curved full-day window positioned above 6 o'clock**—spelling out days like \"\"WEDNESDAY\"\" in crisp typography—perfectly balanced by the independent date window framed at 3 o'clock and the script **\"\"Seikomatic\"\"** logo.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Solid Gold Dolphin Case Back Medallion:\u003c\/b\u003e The ultimate seal of prestige sits embedded on the case back: the iconic **solid gold-embossed Seiko Dolphin medallion** (or deeply etched early crown\/dolphin crest). Certifying its elite factory-regulated chronometric standards and water-resistant construction, the 1963 J13080 33-jewel Seikomatic Weekdater stands as an indispensable, holy-grail cornerstone reference for vintage watch 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\/f1240311103.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.
