As part of the famous 45~ series of King Seiko movements, the 4502 runs at 36,000 bph, or 5 Hz, which provides greater accuracy to the wearer.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe applied hour markers on the sunburst dial are beautiful and elegant, as is the handset. Both the markers and hands are executed without lume and instead the black inlay on the minute\/hour hands which sits underneath a sweeping silver second hand with the hour marker silver and through its centre a single black stripe. The case is curved and polished with a polished bezel. One of our favorite details is the gold King Seiko medallion placed in the center of the case back, a testament to the quality of construction and design present in the watch.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eA BIT OF TRIVIA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe inter-corporate competition between Grand Seiko and King Seiko in the 1960s and '70s is a story that has fascinated all who have heard it. At that point in time, Seiko had two factories to create watches. Grand Seiko was produced at the Suwa factory; King Seiko was produced at the Daini factory. The rationale between having these two separate factories was to promote internal competition in order to build the absolute best watches possible. This 1970 King Seiko is an excellent example of exactly that.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eCaliber 45 was also the last hand assembled King Seiko movement as the models that came afterwards were built on automated production lines. Perhaps, this means that the 45KS has a little more connection in collector’s minds with the Daini Seikosha artisans more than subsequent models. It is also the one and only high beat movement from the Daini factory and was also their last purely hand-wound movement.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eAA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe 45KS movement gave rise to another chronometer grade watch to follow on from the eariler King Seiko 4420-9990. By this time, the King Seiko chronometers were being independently certified by the Japan Chronometer Inspection Institute (JCII, established December 1968) to the same level as the old Swiss standards. At that time chronometer grade was defined to be a mean over five positions within -1.0 to +10.0 seconds\/day which corresponded to Seiko’s internal ‘A’ grade accuracy. This independent certification led Seiko to mark the dials with ‘Officially Certified'\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eSeiko also differentiated those watches that performed to the higher ‘AA’ accuracy grade which was aligned with the then Grand Seiko standard which since 1966 had been defined at -3 to +6 secs\/day. Some 4502-8010 examples met this higher ‘AA’ grade and were marked both on the dial and on the case back medallion with the words ‘Superior Chronometer’\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eOUR THOUGHTS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe King Seiko 4502-8010 Hi-Beat Superior Chronometer Officially Certified stands among the finest timepieces ever produced by Seiko. Celebrated for its exceptional accuracy, sharp design language, and rich horological history, this is a watch that truly represents the peak of vintage Japanese watchmaking. Carefully preserved and ready for its next chapter, this King Seiko has been carried from the past into the present, now ready to be worn, enjoyed, and appreciated well into the future.\u003c\/p\u003e","brand":"Past2PresentWatches","offers":[{"title":"Default Title","offer_id":58040229724547,"sku":"KS9736WO","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/2397\/4423\/files\/king-seiko-4502-8010-sup-front-_4.jpg?v=1778839221","url":"https:\/\/past2presentwatches.com\/products\/vintage-king-seiko-watch-4502-8010-hi-beat-superior-chronometer-certified-1969","provider":"Past2PresentWatches","version":"1.0","type":"link"}
