Overview
This is a classic vintage Seiko 5 automatic wristwatch featuring a robust 23-jewel movement and a distinctive sunburst silver dial. It showcases the iconic recessed crown at the 4 o'clock position and the lightning bolt logo of the Daini Seikosha division. A true workhorse of mid-century Japanese horology, it represents the peak of Seiko's mechanical innovation before the quartz revolution.
Story
In 1963, Seiko revolutionized the watch world by launching the 'Seiko 5' standard, built on five key innovations. This Daini-produced 5126 model features a lightning bolt on the dial, symbolizing a fierce internal rivalry between Seiko's two factories that drove both to perfection.
Maker / Origin
Seiko was founded in 1881 by Kintaro Hattori in Tokyo, evolving from a small clock repair shop into a global watchmaking giant. To foster innovation, Seiko split its production into two competing entities: Suwa Seikosha and Daini Seikosha.
Condition & Value
The watch appears to be in very good vintage condition with light, honest wear on the stainless steel case and bracelet. The dial and hands show minimal signs of aging, and the crystal has only minor surface scuffs. Excellent mechanical functionality and a recent service would push this toward the higher end of the value range.
