Up for sale is an ultra rare vintage Casio × Nike SDB-300W men’s digital sports watch powered by Module 503, produced for the Japan Domestic Market (JDM) in the 1980s. This highly collectible collaboration combines Casio’s classic digital sports watch design with Nike branding, resulting in one of the more unusual and seldom-seen partnership models from the era. The watch is in full working condition, and all features and functions of the watch are working properly, including timekeeping, alarm, chronograph, lap memory, recall functions, and backlight. All parts of the watch are original aside from the strap, which has been replaced with a brand new genuine Casio strap as the original strap deteriorated from age. The watch is in good physical condition, but has visible signs of use and age. The photos best describe its physical condition and should be reviewed carefully.
