Overview
This is a classic mid-1980s Seiko Quartz 100 wristwatch featuring a highly stylized integrated stainless steel bracelet and a clean white dial with a dual-language day-date window. It represents the height of the 'Quartz Revolution' era when Japanese engineering combined sleek, futuristic industrial design with unmatched timekeeping precision.
Story
In the 1980s, Seiko was conquering the global watch market by making ultra-precise quartz technology accessible and incredibly stylish. This model features a dual-language day wheel, a signature touch for Seiko's international market, allowing the wearer to toggle between English and Kanji or Spanish. It represents a moment when a watch wasn't just a tool, but a sleek piece of wearable technology.
Maker / Origin
Founded in 1881 by Kintaro Hattori in Tokyo, Seiko (originally Seikosha) has been a pioneer in horological history, famously introducing the world's first commercial quartz wristwatch, the Astron, in 1969. This single innovation disrupted the entire Swiss watchmaking industry, establishing Seiko as a global powerhouse of precision manufacturing.
Condition & Value
The watch appears to be in very good cosmetic condition with light surface scratches on the stainless steel case and bracelet consistent with age. The dial and hands are clean and free of moisture damage, though the movement should be tested with a fresh battery to ensure the quartz circuit is fully operational.
