Seiko Dolce was presented as a long-service award for Kajima Corporation (鹿島建設株式会社) on February 22, 1986, as beautifully documented by the custom caseback engraving. Manufactured in October 1984 (Serial: 4O1700), it features a highly specialized SHA (Silver Hard Alloy) case, which was engineered to provide superior scratch resistance and a lasting, brilliant luster. The dial is a work of high-end JDM art, featuring a vertically brushed silver texture and an elegant gold-trimmed inner bezel that adds a sophisticated "tuxedo" contrast to the sharp geometry.

This piece is powered by the Caliber 9521, a high-precision quartz movement that represents the technical excellence Seiko's Dolce line was famous for in the mid-80s. With its ultra-slim profile and unique architectural lugs, it remains a quintessential daily driver for the discerning professional who values both historical pedigree and refined proportions.
