Story & Heritage
Seiko is one of Japan's most influential watchmaking manufacturers, founded in 1881 by Kintaro Hattori. Celebrated for its technical innovation and precision engineering, the brand transformed modern horology with the introduction of the world's first commercially available quartz wristwatch, the Seiko Quartz Astron, in 1969.

During the 1980s, Seiko became particularly renowned for its elegant quartz dress watches, combining advanced Japanese technology with distinctive geometric designs and refined materials.
This vintage Seiko Tank reflects the sophisticated aesthetics of that era, when rectangular cases, integrated bracelets and two-tone finishes became symbols of modern elegance.
Its minimalist grey dial, architectural gold-tone details and slim rectangular proportions demonstrate Seiko's ability to combine practical precision with fashionable design. The original integrated bracelet adds to the watch's period character, creating a harmonious appearance between case and bracelet.
A refined vintage Japanese timepiece for collectors of Seiko, elegant quartz watches and distinctive 1980s design.
