Rare Vintage Seiko C515-5009 Men’s Classic Digital Calculator Watch JDM 1980s

Up for sale is an extremely rare vintage Seiko C515-5009 men’s classic digital calculator watch from the Japan Domestic Market (JDM), dating to the 1980s. This iconic model features a full keypad calculator layout integrated into a stainless steel case, representing one of Seiko’s most innovative and sought-after digital designs of the era. The watch has been lightly tested and appears to be in working condition across its functions and modes. However, when the backlight is pressed and held, the watch glitches and resets. This issue has not been diagnosed, and there may be additional underlying issues. Aside from the backlight reset issue, all other functions appear to operate properly based on limited testing. All parts of the watch are original. The watch is in good physical condition and has signs of use and age, but the photos best describe its physical condition and should be reviewed carefully.
