[Seiko] A late-1940s Extra Flat from Seiko’s early post-war years
Here is one of the earliest Seikos in my collection: a late-1940s Seiko Extra Flat.
The Extra Flat appeared around 1948, when Seiko was rebuilding its civilian watch production after the war. It was powered by the hand-wound 10B movement from Daini Seikosha’s Kameido factory, with the traditional small-seconds layout that Seiko used before introducing its first centre-seconds watch, the Super, in 1950.

The history is interesting, but the dial is what really attracted me. The bold sector-style chapter ring, raised gold numerals and markers, small seconds and little applied “Snake S” give it much more personality than I expected from such a compact dress watch. There is plenty of ageing, but I think the patina suits the design rather than detracting from it.
“Extra Flat” is also a wonderfully literal name. The watch is small and slim by modern standards, but the long curved lugs give it surprising presence on the wrist.
Nearly eighty years later, it still looks remarkably stylish—and very different from the Seiko designs most people know today.
