Up for sale is a rare vintage Seiko Seikomatic Slimdate men’s 30-jewel automatic dress watch, produced for the Japan Domestic Market (JDM) during the 1960s. The Seikomatic Slimdate series represents some of Seiko’s refined automatic dress watches of the era, combining an elegant slim-profile design with a high-jewel automatic movement and classic mid-century styling. The watch is in full working condition and is running and holding accurate time over a 24-hour period. The watch features a special commemorative engraving on the case back from Toyo Rayon, which translates to “Commemorating 30 years of service” and “Presented to Mr. Yosankichi/Yosakichi Iwamoto.” This engraving adds an especially interesting piece of Japanese corporate history and provenance to the watch, indicating that it was presented in recognition of 30 years of service with Toyo Rayon. The watch is fitted on an aftermarket black leather strap, which complements its gold-tone case and classic dress-watch appearance. The watch is in good vintage physical condition with signs of use and age. The photos best describe its physical condition and should be reviewed carefully by interested buyers.
