Driven by the legendary 25-jewel Caliber 4502 ultra-high frequency manual-winding movement, this masterpiece beats at a staggering 36,000 vibrations per hour. This caliber was built to compete at the highest levels of chronometer trials, offering a silky-smooth sweep and technical sophistication that rivaled Grand Seiko.\u003c\/p\u003e\n\u003cp\u003eHaving undergone a comprehensive service, the movement winds with crisp, tactile fluidity and operates with optimal high-frequency vigor. The original silver-white dial remains entirely untouched, developing a gentle, warm patina that reflects its authentic vintage journey. This natural aging lends an unmistakable charm to the face, while the sharp applied indices, gilded handset, and framed date display at 3 o'clock retain their executive presence.\u003c\/p\u003e\n\u003cp\u003eThe SGP case is beautifully preserved, retaining its original factory geometry with the powerful, sharp-edged lug lines of the 7001 profile. Unlike many gold-plated pieces of this era, the gold layers remain remarkably intact, providing a rich, warm canvas that captures light beautifully. A standout feature is the original King Seiko gold medallion on the caseback, which remains remarkably well-preserved. The watch head is factory-correct, keeping its original dial, crystal, case, crown, and medallion intact. It comes paired with a premium black leather strap.\u003c\/p\u003e\n\u003cp\u003eCollectors fiercely pursue the 4502-7001 for its legendary 36,000 BPH hand-wound caliber, instant date change, and dominant role in the golden age of Japanese watchmaking. This 1970 specimen provides a perfect balance of raw technical sophistication and refined gold elegance.\u003c\/p\u003e\n\u003cp\u003e💵 Price: $500 + $40 shipping (via USPS\/Singapore Post)\u003cbr\u003e💳 Payment via PayPal F\u0026amp;F or G\u0026amp;S, Payoneer or Wise\u003c\/p\u003e\n\u003cp\u003e#KingSeiko #VintageSeiko #Seiko4502 #HiBeat36000 #ManualWinding #GoldMedallion #KS #SGP #GrammarOfDesign #SeikoCollector #AvailableNow #hnvintagepieces\u003c\/p\u003e","brand":"HN Vintage Pieces","offers":[{"title":"Default Title","offer_id":50429848322241,"sku":"WATCH-99","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/7250\/0161\/files\/IMG_0882.jpg?v=1785081484","url":"https:\/\/hnvintagepieces.com\/products\/serviced-rare-vintage-1970-king-seiko-ks-hi-beat-36000-sgp-medallion-25-jewels-4502-7001","provider":"HN Vintage Pieces","version":"1.0","type":"link"}
