This is a vintage mechanical pocket watch signed “CHRONOMETER ZELMA (ZELMA)”, manufactured in Japan during the immediate post-war period, from the late 1940s to the early 1950s, by 精工舎, the predecessor of Seiko. ZELMA is known as one of Seikosha’s short-lived pocket watch lineages produced during Japan’s post-war reconstruction era. Due to the brief production period and historical circumstances, surviving examples are scarce, and documentation is limited. As a result, ZELMA pocket watches are today considered collectible vintage timepieces representing an important transitional phase in Japanese watchmaking. Model and Construction The dial of this watch is clearly signed “CHRONOMETER ZELMA”. The movement architecture and bridge layout correspond to what is generally referred to as a Zelma-type movement. This particular movement does not bear SEIKOSHA engravings or jewel count markings. However, multiple ZELMA pocket watches with identical construction characteristics have been confirmed, indicating that ZELMA was produced in multiple specifications and variants, rather than a single standardized configuration. Accordingly, this watch is best identified as a legitimate ZELMA variant, distinct from higher-grade or differently marked commercial versions. Please note: This individual watch does not feature any government, institutional, or commemorative engraving. There is no evidence indicating special-purpose or presentation use for this particular example. Historical Context In the late 1940s, Japan’s watch industry was undergoing reconstruction following World War II. During this period, Seikosha continued to manufacture reliable mechanical timepieces using established pre-war and wartime expertise. ZELMA pocket watches are regarded as products of this transitional era, bridging traditional Japanese pocket watch craftsmanship with post-war production realities. Today, they are appreciated by collectors as tangible artifacts of Japan’s horological history. Condition The watch shows age-related wear, scratches, and patina consistent with its age Dial shows visible aging and discoloration As a vintage mechanical timepiece, long-term accuracy and continuous operation are not guaranteed Offered in as-is condition Please review all photographs carefully before bidding. This watch is recommended for vintage pocket watch collectors seeking a historically significant Japanese timepiece.
