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).
The Grand Seiko’s 9F quartz movement is assembled entirely by hand by two expert craftsmen. In 1973, Seiko announced the world’s first LCD quartz watch with six-digit digital display. Grand Seiko’s vast resources and immense passion for the art of horology enable it to have a unique operational structure that allows its watchmakers to innovate and obsess over new technologies and complications. This is how significant technologies like Spring Drive (after 28 years of R&D) and its Kodo Constant-Force Tourbillon (that won the GPHG Chronometry Prize) were created. Grand Seiko is celebrated by collectors for its ability to offer many of its popular Sport, Heritage, and Evolution 9 models in titanium, a metal that is lighter and harder than steel.
