Seiko Holdings Corporation (SEIKO) delegates a large portion of the manufacturing in its watch business to SII and EPSON. Most of watches manufactured by SII are sold through the Seiko Watch Corporation, a subsidiary of Seiko Holdings Corporation. In recent years Seiko Instruments has tried to establish its own marketing channel and brands – Sizukuishi Watch, appetime, J.SPRINGS, ISSEY MIYAKE, tsumori chisato, ALESSI, cacharel, etc.
On January 26, 2009, Seiko Instruments and Seiko Holdings announced that the two companies will be merged on October 1, 2009 through a share swap. Seiko Instruments became a wholly owned subsidiary of Seiko Holdings on October 1, 2009.
