Management Number 0610 0527E3855 511 #36 A timepiece from SEIKO — Japan's proudly world-renowned watch brand — this is a slim and stylish men's wristwatch representative of the early 1980s. It embodies the high-precision, ultra-thin quartz movement technology with which SEIKO was leading the world at the time, and offers a light, comfortable fit that sits smoothly on the wrist. The watch is currently running accurately as a working piece. The timeless round case features clean, uncluttered bar indices and a practical date (date) display, offering outstanding legibility. It fits elegantly at the cuff of a business suit, and equally complements a smart casual look on days off — a timepiece that adds a sincere and intellectual impression to the adult wrist.
