Created to establish internal rivalry and drive uncompromising accuracy, this legendary reference launched the historic \"\"KS\"\" line, setting the standard for Japanese high-grade luxury hand-wound watchmaking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Over-Engineered 25-Jewel Manual-Wind Caliber Heart:\u003c\/b\u003e Powering this historic flagship is the elevated **25-jewel manual-wind movement** (derived from the Cronos base architecture). Operating at **18,000 vibrations per hour (vph)**, it features Seiko’s proprietary **Diashock** anti-shock protection system. Engineered with a lavish **25-jewel specification** to minimize gear-train friction across every critical pivot, this movement delivers exceptional chronometric stability, long power reserve, and a satisfyingly smooth tactile manual-winding action.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"J14102E\"\" Heavy-Lug Case Geometry:\u003c\/b\u003e The reference **J14102E** is globally revered among vintage collectors for its distinctive, commanding case architecture. Available in solid stainless steel or heavy 14K gold-filled options, it features thick, sharp-faceted **\"\"thick-style\"\" dress lugs** and a clean, slim bezel profile. This muscular yet refined geometry creates a bold wrist presence that glides effortlessly under formal attire.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eImmaculate Non-Date Dial Balance and Carved Typography:\u003c\/b\u003e The dial of the **J14102E** is a study in early-1960s visual purity, set against a radiant silver sunburst canvas free from calendar clutter. It displays **hand-applied, multifaceted rectangular block hour markers** (with double-width indices at 12 o'clock) paired with razor-sharp, polished dauphine hands. The dial is proudly adorned with the iconic applied or carved **\"\"KING SEIKO\"\"** script and the special star symbol above 6 o'clock indicating solid SD (Special Dial) hour markers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Gold KS Crest Medallion Heritage:\u003c\/b\u003e The ultimate hallmark of this 1961 treasure sits proudly on the case back: the iconic, **solid gold-embossed King shield medallion** (or deeply stamped KS crest). This emblem historically certified its elite factory status and supreme hand-regulated precision. Standing as the foundational forefather of all King models that followed, the J14102E 25-jewel first generation remains an indispensable, top-tier investment-grade centerpiece for serious horological purists 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\/k1239023173.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.
