Story & Heritage
Founded in Japan in 1881 by Kintaro Hattori, Seiko has become one of the most influential names in the history of watchmaking, recognised worldwide for its innovation, precision and exceptional commitment to quality.
In 1969, Seiko introduced the Astron, the world's first commercially available quartz wristwatch, marking a revolutionary moment in horological history.

This technological breakthrough transformed the watch industry, making highly accurate timekeeping increasingly accessible and establishing Japanese watchmaking as a major force in the global market.
During the following decades, Seiko developed an extensive collection of quartz wristwatches, combining advanced Japanese movements with elegant designs inspired by both contemporary fashion and traditional European watchmaking.
The rectangular Tank-style watch became an enduring symbol of sophistication.
Originally popularised during the early twentieth century, this distinctive case shape offered an elegant alternative to conventional round watches. Its geometric proportions, balanced dial and refined appearance made it a favourite among those who appreciated timeless design.

This Seiko Tank Quartz reflects that tradition. Its gold-plated rectangular case, two-tone dial and stylised Arabic numerals create a harmonious composition that recalls the elegance of classic European design, while its Japanese quartz movement provides practical everyday precision.
The restrained two-hand configuration reinforces the minimalist character of the watch, allowing its carefully proportioned dial and architectural case to remain the central design elements.
Unlike oversized contemporary watches, this model offers discreet proportions and a sophisticated vintage aesthetic that works beautifully on both men's and women's wrists.

Today, vintage Seiko quartz watches are appreciated by collectors for their reliable engineering, distinctive period designs and excellent representation of Japanese watchmaking heritage.
With its elegant rectangular case, refined two-tone dial and classic black leather strap, this Seiko Tank remains a timeless accessory that combines style, history and practicality.
A charming vintage piece for collectors of Seiko, Japanese quartz watches and elegant rectangular timepieces.
