Born from the legendary **Daini Seikosha (Kameido)** factory under reference **4502-7001**, this historic masterpiece was engineered explicitly to challenge the elite Swiss watchmaking houses. Positioned to deliver world-shaking mechanical precision, it served as an uncompromising status symbol for Japan's visionary leaders and top-tier executive class.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Legendary 25-Jewel Caliber 4502 Ultra-High-Beat Heart:\u003c\/b\u003e This watch is powered by the magnificent **25-jewel Caliber 4502**, a high-grade manual-wind engine operating at a blistering frequency of **36,000 vibrations per hour (10 beats per second)**. Sharing its elite architecture with the world-renowned Grand 45-series and the historical observatory chronometers that conquered international Swiss trials, this over-engineered movement deployed **25 jewels** to tame the immense kinetic friction of high-frequency operation, integrating a **seconds-hacking mechanism** and an instantaneous date-change system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Ultimate Geometric Execution of the \"\"Grammar of Design\"\":\u003c\/b\u003e The reference **4502-7001** is globally celebrated among vintage purists as a textbook monument of Taro Tanaka's revolutionary **\"\"Grammar of Design\"\"** philosophy. The solid stainless steel case features **incredibly sharp, wide, and angular multi-faceted lugs** finished with zero-distortion mirror polishing and precise contrasting brushed textures. This low center-of-gravity, muscular structure was drawn explicitly to master the interplay of light and shadow, defining the aesthetic soul of luxury Japanese watchmaking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eClinical Calendar Dial Legibility and Balanced Harmony:\u003c\/b\u003e By utilizing a date-only layout instead of a dual-calendar disk, the dial achieves a magnificent level of **refined visual balance and clean symmetry**. The radiant silver sunburst canvas features **hand-applied, multifaceted chunky block indices** paired with razor-sharp Dauphine hands, ensuring split-second professional legibility. The face is beautifully completed by a neatly framed date window at 3 o'clock, the proud applied **\"\"KS\"\" shield emblem**, and the bold typography proclaiming its **\"\"HI-BEAT 36000\"\"** velocity at 6 o'clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe Sovereign Glory of the Gold KS Medallion:\u003c\/b\u003e Manufactured in the milestone mechanical year of **1970**, the 4502-7001 remains one of the most highly coveted, universally respected \"\"holy grails\"\" for serious vintage enthusiasts worldwide. The ultimate hallmark of its premium internal pedigree sits embedded on the screw-down case back: a **solid gold, crisply embossed \"\"KS\"\" Medallion** designed to officially guarantee its high-luxury manufacturing credentials. It stands as a profound testament to an era when Kameido perfected the high-frequency instrument to an eternal, heirloom standard.\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\/w1233304831.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.
