Rare Vintage Casio 31QR-20 Men’s Digital Chronograph Sports Watch JDM 1970s

Up for sale is a rare vintage Casio 31QR-20 men’s digital sports watch, produced exclusively for the Japan Domestic Market (JDM) during the 1970s. This early-generation digital model highlights Casio’s pioneering role in digital watchmaking, featuring a stainless steel case, clean digital display, and classic quartz technology from the era. The watch is in full working condition, and all features and functions operate properly, including timekeeping, day, date, and stopwatch functions. The digital display is clear and easy to read. Important note: on occasion, the bottom right pusher can become slightly stuck after a firm press. When this happens, lightly pressing the button again causes it to release back out normally. This does not occur on every press, but it does happen intermittently. All parts of the watch are 100% original, including the stainless steel case, bracelet, clasp, and internal module. The watch shows signs of use and age, consistent with a vintage piece from the 1970s. The photos best describe its physical condition and should be reviewed carefully.
