Seiko Corporation began developing quartz time-keeping devices in the late 1950s. By 1967, the company had developed a wristwatch prototype, and began marketing the 35SQ Astron, the first commercial quartz wristwatch, in 1969.  The idea was based on a discovery by Warren Marrison at Bell Labs in 1927, who developed the first quartz clock.
