Rare Vintage Seiko Unique J13013 Seikosha 17J Men’s Classic Dress Watch JDM 50s

Up for sale is a Rare Vintage Seiko Unique J13013 men’s classic dress watch, produced for the Japan Domestic Market (JDM) in the 1950s. Powered by a Seikosha 17-jewel manual wind movement, the Unique was one of Seiko’s early post-war dress watch lines and is highly regarded for its elegant styling and dependable mechanical design. The watch is in full working condition and is running and holding accurate time over a 24-hour period. I believe the original Seiko leather strap and signed Seiko buckle are original to the watch, but I cannot say for certain. It should be noted that the crystal is aftermarket and has not been seated correctly. It is slightly loose and will likely need to be adjusted so that it does not fall off. This should be a simple repair for any competent watchmaker. Beyond this issue, the watch is in good physical condition with signs of use and age. The dial has developed a beautiful natural patina that gives the watch exceptional vintage character. The photos best describe its physical condition and should be reviewed carefully.
