Rare Vintage Casio Weather Station Barometer BM-500W Men’s Digital Sports Watch

Up for sale is a rare vintage Casio Weather Station BM-500W men’s digital sports watch, a Japan Domestic Market (JDM) release from the late 1980s powered by Module 923. This model is highly sought after by collectors because it predates the G-Shock line, and many of the design cues and functional ideas later seen in early G-Shock models were influenced directly by this watch. Part of Casio’s innovative Weather Station series, the BM-500W combines rugged styling with advanced technology for its era, including a built-in barometer alongside Casio’s full suite of digital timekeeping functions. The watch is in full working condition, and all features operate properly, including timekeeping, alarm, stopwatch, calendar, hourly signal, and barometer. I am unsure if the strap is original to the watch. The watch is in excellent physical condition, showing only the most minor signs of use, but the photos best describe its physical condition and should be reviewed carefully.
