Seiko produced the first generation of Grand Seikos from 1960 to 1975. Seiko itself caused Grand Seiko’s demise: the company’s pioneering advances in quartz watch technology killed demand for mechanical watches. It stopped mak- ing Grand Seikos in 1975. By the early it halted virtually all mechanical watch production. Miraculously, a decade later, Seiko mechanicals came back, when the trusty tick-tock found new life as a luxury item.
