Up for sale is a stunning and historically significant piece of early Japanese horology: a rare ladies' mechanical wristwatch from the mid-1920s to 1930s, manufactured by Seikosha (K. Hattori & Co.), the precursor to the modern Seiko brand.This timepiece comes from the pivotal era when wristwatches were transitioning into daily fashion items, making it an exceptional find for collectors of vintage military, art deco, or early Asian horology.
The Movement: The watch features an authentic, manual-winding mechanical movement explicitly stamped with the historical SKS (Seikosha Kabushiki Kaisha) mark, alongside the highly desirable "SKS Adjusted" engraving, indicating factory tuning for enhanced accuracy.
The Bracelet: Comes fitted on a beautiful, period-correct engraved metal bracelet that perfectly complements the Art Deco aesthetic of the case.
The internal hinged caseback retains its rare, original Crane (Tsuru) stamp, which was Seikosha’s internal hallmark for premium domestic case manufacturing.
The watch is currently not running and the movement is seized. Being sold strictly as-is for a collector, watchmaker, or restoration project.
