The worlds first production quartz watch was released in December 1969. Throughout the 1970s there was a cycle of rapid development to transform this new technology from a science like project, into a high-end, cutting edge form of haute-horology. 
 
Subsequently, these quartz pieces that gave Seiko so much success, cannibalised not just other brands mechanical pieces, but also Seiko’s. The Grand Seiko pieces, King Seiko, Lord Matic names all had to undergo revamping as sales of mechanical dropped off. As such these names shifted, with King Seiko now being revamped as King Quartz, making use of fresh quartz technology.
