Spicer Greene Jewelers Seiko

The story of Seiko began in 1881, when a 21 year old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. Today, after more than 130 years of innovation, Kintaro Hattori’s company is still dedicated to the perfection that the founder always strove to achieve.
