Since its founding in 1881, Seiko has adhered to the spirit of “Always one step ahead of the rest” and has continuously provided innovative products that have moved ahead and touched hearts. Seiko has proactively created whatever is needed to produce these products and deliver them to the world.

At the end of the 1960s, watchmakers competed to develop quartz watches. Despite their efforts, there were no prospects for the commercialization of low-power-consuming CMOS-ICs that were superior for use in watches. Under these circumstances, Seiko Instruments Inc. and a U.S. venture company jointly completed the first CMOS-IC model and launched the Seiko 36SQC as the world’s first quartz watch to integrate a CMOS-IC in 1970.

Subsequently, we advanced toward further power saving and higher-function CMOS-ICs and thus expanded applications beyond watches to industrial and household equipment. Today, we have broadened our lineup to ICs for power sources, sensors and memories and boast a world top-level share for lithium rechargeable battery protection ICs and a top share of the domestic market for vehicle-mounted EEPROMs. These products are used in various fields.
