Up for sale is a rare vintage Seiko Unique J13005 men’s manual wind dress watch from the 1950s, produced by Seikosha for the Japan Domestic Market (JDM). The Seiko Unique series represents an important period in Seiko’s history as the company continued to establish its reputation for reliable and well-made mechanical timepieces during the postwar era. This example features the desirable 15 jewel movement and classic mid-century styling that remains highly sought after by collectors today.
The watch is in full working condition and is running and holding accurate time over a 24 hour period.
All parts of the watch are original, including the original expandable bracelet. The watch is in very good vintage physical condition with signs of use and age consistent with a vintage timepiece. The photos best describe its physical condition and should be reviewed carefully.
An especially interesting feature of this example is the original presentation engraving on the caseback. The engraving reads “ 勤続二十年 東洋高圧 ,” which translates to “20 Years of Service – Toyo High Pressure Industries.” This indicates the watch was originally presented to an employee in recognition of twenty years of service with Toyo High Pressure Industries, a major Japanese industrial company. Such presentation watches provide a unique connection to Japanese corporate history and add to the watch’s collectible appeal.

► ARCHIVE FILE: SEIKO — BRAND HISTORY
From Kintaro Hattori's 1881 Tokyo shop, Seiko grew into a vertically integrated manufacturer that reshaped both mechanical and electronic watchmaking. Grand Seiko, landmark dive watches, the 6139 automatic chronograph, and the 1969 Astron quartz watch chart a history of relentless competition and invention that left an unusually broad vintage catalog.
