Seiko’s Business

Watches are not all Seiko provides.

Watches are not all that Seiko has to offer society. Our business activities also include the provision of electronic devices and system solutions as well as the operation of a retail business.


In the founder's sprit of "Remain one step ahead of our time," Seiko has developed its watch business by combining its unique cutting-edge technology with traditional craftsmanship. To fully harness this uniqueness, we has remained one of the few manufacture d'horlogerie (full-scale manufacturers) in the world that consistently engage in parts production, assembly, and adjustment. Our main products are four global brands: Grand Seiko, which seeks the essence of watches, Seiko Astron, the world's first GPS solar watch, Seiko Prospex, descended from the first domestically produced diver's watch, and Seiko Presage, which exerts a made-in-Japan mechanical charm.
