While the watches are marked "Limited Edition" they are unnumbered so I do not know how many are made. I posted the case sizes above from other sources, but they do not seem to match up with my own inspection. Will try to get the correct case size measurements. 


About Seiko. In 1881, when Kintarō Hattori opened a watch and jewelry shop called "K. Hattori" in Tokyo, Japan. Eleven years later, he began to produce clocks under the name Seikosha. The first K. Hattori wristwatches were produced in 1913. The Seiko brand was first used in 1924. Today the company is named Seiko Holdings Corporation.
