Born from the prestigious **Suwa Seikosha** factory under reference **5626-7120**, this executive timepiece was engineered specifically to challenge the finest international chronometer houses, serving as a proud status symbol during the heights of the Showa economic miracle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe High-Beat 25-Jewel Caliber 5626 Automatic Heart:\u003c\/b\u003e This masterpiece is powered by the legendary **25-jewel Caliber 5626**, an in-house automatic engine operating at a swift high-beat frequency of **28,800 vibrations per hour (8 beats per second)**. Highly celebrated by vintage purists for its remarkably slim architecture and superior daily stability, this movement deploys a lavish **25-jewel specification** to control gear-train friction. It integrates modern executive conveniences including **hacking seconds**, quick-set dual calendar functionality, and smooth manual-winding capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eArchitectural \"\"7120\"\" Grammar of Design Case Geometry:\u003c\/b\u003e The reference **5626-7120** is globally distinguished among vintage collectors for its textbook execution of Taro Tanaka's foundational **\"\"Grammar of Design\"\"** philosophy. The solid stainless steel case features extraordinarily sharp, muscular facets and robust, broad-shouldered lugs finished with zero-distortion mirror polishing. This low center-of-gravity design allows the mechanical instrument to sit completely flush against the wrist, sliding weightlessly under a tailored shirt cuff.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eImmaculate Weekdater Dial Harmony and Bilingual Utility:\u003c\/b\u003e The dial of the **5626-7120** is a masterclass in mid-century visual restraint, showcasing a radiant silver sunburst canvas. It features **hand-applied, multifaceted rectangular block indices** with elegant black insert details and razor-sharp hands that catch light with high-contrast legibility. Symmetrically framed at 3 o'clock, the dual-calendar window houses a **bilingual (English\/Kanji) day disk** alongside a quick-set date configuration for high-efficiency daily legibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Gold KS Medallion or Engraved Case Back Heritage:\u003c\/b\u003e The ultimate hallmark of this 1972 treasure sits proudly on the case back: the iconic **King Seiko (KS) medallion or deeply engraved KS crest**. This emblem historically certified its elite manufacturing status and factory-regulated timing accuracy. Built to an uncompromising heirloom standard that easily transcends passing fashion trends, the 5626-7120 stands as a profound, investment-grade testament to the golden age of Japanese mechanical design.\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\/b1235892431.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.
