Morioka is a city nestled among forests and streams, and blessed with a panoramic view of the magnificent Mount Iwate. It was in this natural setting, one perfectly suited for watchmaking, that we established Morioka Seiko Instruments Inc. in 1970.
Today, as a watch-manufacturing base of the Seiko Instruments Inc. (SII) Group, we offer a variety of products to customers all over the world. Our inherent craftsmanship creates high classed watches with the world's highest accuracy. At the same time, our highly automated state-of-the-art production line produces movements for quartz watches.
We are proud of our pioneer spirit and our position as the world's top watch-manufacturing company. While uniting our technical skill and leading edge technology, and harmonizing with rich natural environment, we will continue to make a product enjoyable and beloved by the people of the world.
