Daini Seikosha ("the Second Seikosha") was founded in 1937 as a watch production operation for Seikosha K. Hattori & Co, Ltd., forerunner of today's Seiko. Morioka Seiko Instruments, founded in 1970, began producing watch movements two years later. It was brought together with Daini Seikosha to become Seiko Instruments & Electronics in 1983 and was brought into Seiko Holdings in 2009. Domestic watchmaking was brought to Morioka, Iwate in 1999 and a high-end watchmaking operation, Shizukuishi Watch Studio, was founded in 2004. Today, Shizukuishi is responsible for Grand Seiko and Credor.
