Casio Multi Alarm BA-80 Men’s Vintage Digital Sports Watch Module 462 JDM 1980s

Up for sale is an extremely rare vintage Casio Multi Alarm BA-80 men’s digital watch, produced for the Japan Domestic Market (JDM) during the 1980s and powered by Module 462. This uncommon variation of the Multi Alarm series is an exceptionally difficult-to-find model from Casio’s golden era of digital watchmaking. What makes this particular example especially desirable is the inclusion of its original Casio Alarm Booster attachment, an extraordinarily rare accessory that is almost never encountered alongside surviving examples of the BA-80. The watch is in full working condition, and all features and functions are working properly, including the alarms, dual time, chronograph, timekeeping, and backlight. All parts of the watch are original, including its original Casio strap. Most notably, the watch comes complete with its extremely rare and highly desirable original Casio Alarm Booster attachment. This ingenious accessory clips directly onto the speaker grille on the front of the watch and is designed to amplify the sound of the alarm. The Alarm Booster is an unusual example of Casio’s experimental approach to digital watch technology during the 1980s, and finding one still accompanying its original watch is exceptionally uncommon. The attachment can also be removed, allowing the watch to be worn in its standard configuration. The watch has signs of use and age. The photos best describe its physical condition.
