Overview
This is a classic vintage Seiko 5 automatic wristwatch featuring a sunburst silver dial, day-date complication, and the distinctive lightning bolt logo of the Daini Seikosha factory. Powered by the robust 23-jewel 5126 automatic movement, it represents the golden age of Japanese mechanical watchmaking.
Story
In 1963, Seiko revolutionized the watch world by launching the Seiko 5, built on five key innovations. This Daini-produced model features a lightning bolt logo, symbolizing a fierce internal rivalry that drove Seiko to beat the Swiss.
Maker / Origin
Seiko's history is unique for its internal competition between two independent factories: Suwa Seikosha and Daini Seikosha. This healthy rivalry was intentionally fostered by Seiko management to spur innovation, ultimately leading to Seiko winning Swiss chronometer competitions.
Condition & Value
The watch appears to be in excellent cosmetic condition with light surface scratches on the stainless steel case and bracelet consistent with age. The dial and hands are remarkably clean with no visible corrosion or water damage.
