Casio BH-100W-6V Bio Graph – Vintage NOS / New Old Stock

A particularly rare and unusual Casio Bio Graph BH-100W-6V, preserved in New Old Stock (NOS) condition.

This watch has never been worn and comes as a complete original vintage set with its original Casio box, original period tag and original warranty documentation.

The BH-100W belongs to Casio’s fascinating Bio Graph series and features the distinctive biorhythm graph function. By entering a date of birth, the watch calculates and displays three different biorhythm cycles — Physical, Sensitivity and Intellect — directly on its digital display. The watch can store up to four birth dates, making this one of the most unusual digital Casio models from its era.

It is equipped with Casio module 946, 50 m water resistance, 1/100-second stopwatch, three daily alarms and hourly time signal.
