Up for sale is an ultra-rare vintage Casio BP-400 men’s Ana-Digi wristwatch featuring integrated blood pressure and pulse monitoring, powered by Module 770. Produced exclusively for the Japan Domestic Market (JDM) in the 1990s, this groundbreaking model remains one of the most advanced and collectible examples of Casio’s medical-tech digital watch engineering. The watch is in full working condition—all functions operate properly, including timekeeping, analog hands, digital display, pulse sensor, and blood pressure monitoring system. This hybrid design combines traditional analog movement with innovative digital health monitoring technology from the golden era of Casio. Unlike other Casio blood pressure monitor models, the BP-400 was designed without a sound function, so there is no audio output for alarms or button presses.

The caseback also bears a special engraving commemorating the 60th Anniversary of Kokushin Co., Ltd. (October 1995), adding to its historical and collectible appeal.
