NOS Rare Vintage Casio BP-400 Blood Pressure Monitor Men’s Ana-Digi Watch JDM

Up for sale is an ultra-rare vintage Casio BP-400 Ana-Digi Blood Pressure Monitor wristwatch, equipped with Module 770, produced exclusively for the Japan Domestic Market (JDM) in the 1990s. This model represents one of Casio’s most advanced and experimental medical-tech releases, combining traditional analog timekeeping with digital blood pressure and pulse monitoring. These were extremely expensive and niche when new, and full sets are virtually impossible to find today. This particular BP-400 is even more special: the caseback is factory-engraved as a 60th Anniversary commemorative edition for Kokuyo Co., Ltd. (October 1996), making it a documented corporate-issued, limited production piece. The watch is in full working condition, and all features and functions operate properly, including timekeeping, analog display, digital display, pulse monitoring/blood pressure measurement. As designed on this specific BP-400 model, there is no sound function for button presses. The watch is brand new in box with original paperwork and the original BP-400 VHS instructional tape — an unbelievably rare complete set. All parts of the watch are 100% original, including the stainless steel bracelet with dual-tone gold accents and Casio-signed clasp. The watch is in mint physical condition. The photos best describe its physical condition.
