The King Seiko line was created by Daini Seikosha to compete directly with Grand Seiko. The first King Seiko was released the year after the first Grand Seiko, in 1961. The first King Seikos were made with unmarked, manual winding, 25 jewel movements, that were not internally tested chronometers. This was followed by the release of the ’44KS’ movement in 1964, a remake of the 44GS, a manual winding, 18,000 bph, movement with a screwdown case back. In 1968, the 45KS was introduced with a manual winding, 36,000 bph hi-beat movement – again meant to compete with the 45GS but generally less accurate and with less finishing.
King Seiko Certified Chronometer and Superior Certified Chronometers were released between 1968 and 1970. These first two were produced by Daini Seikosha but one of the most impressive King Seikos, the 56KS, was actually made by the Suwa Seikosha. The King Seiko 56KS movements were the same as those used in Grand Seiko’s 56GS series, Seiko Lord Matic watches, and Seiko chronometers. It was also introduced in 1968 and featured an automatic, 28,800 bph movement with 25 jewels and a 47-hour power reserve. These watches were all marked ‘Hi-Beat’ on the dial despite being only 28,800 bph (instead of 36,000).
