New Old Stock NOS

This maybe the only complete full set of the yellow BP-100 in the world.

Original BP-100 straps

Unbeatable condition and everything works, sensor is 100% working

The Casio BP-100 Yellow is a highly collectible, distinctively vibrant variation of Casio's ground-breaking 1990s blood pressure monitoring timepiece.
Originally introduced around 1990–1992, this specific version departs from the clinical look of the standard black model by featuring an eye-catching, all-yellow resin case offset by black text and bold accents. 
A "complete full set" (often abbreviated by collectors as NIB / New in Box or NOS / New Old Stock) of a vintage Casio BP-100 Yellow means it survives with all the original accompanying materials Casio issued in the early 1990s.
Finding a full set is incredibly rare today and commands a massive price premium among vintage collectors.
A genuine, completely full 1990s set for the BP-100 must include the following specific components:
1. The Outer Packaging & Presentation Case
  • The Cardboard Outer Sleeving: A dark black cardboard box featuring bold red and pink "heartbeat/pulse wave" graphics sprawling across the front, alongside massive stylized "BP-100" lettering.
  • The Hard Plastic Clamshell Case: Inside the cardboard sleeve sits a rigid, black plastic presentation box. The top lid is embossed with the Casio logo and "BP-100". The lower interior features a custom, fitted red plastic or velvet tray insert molded specifically to hold the watch head securely alongside the instructional media.
2. The Period-Correct Instructional Media
  • The Blood Pressure Instruction Cassette Tape: The most unique piece of the full set. Casio included a physical audio compact cassette tape housed in its own clear/pink mini-case. This audio cassette contains recorded voice instructions guiding the user on how to correctly place their finger on the sensor and interpret the pulse readings.
  • The "How to Begin" Quick Start Guide: A small, bright white and red paper pamphlet titled "How to begin your Blood Pressure/Pulse monitoring". It displays a graphical layout of an ECG heart rhythm on the front cover.
  • The Main Owner's Manual: The official thick, multi-language booklet detailing Module 900 operation, settings, and health tracking storage limits.
Yellow Design Variations

The "yellow" designation for the BP-100 generally refers to one of three aesthetic states found in the collector community:
  • The Yellow Case Version: This is the factory-released solid colour model. It features a bright yellow resin bezel and strap paired with black lettering. It perfectly encapsulates the bold, neon-influenced fitness aesthetic of the early 1990s. 
  • The Black & Yellow Accent Version: A sportier iteration of the standard black model that features bright yellow highlight lines encircling the LCD screen and front buttons. 
  • The "Yellowed" White Version: Due to the age of vintage resin, the rare off-white/light-grey version of the BP-100 frequently suffers from severe UV degradation and oxidation, causing the resin to turn a yellowish hue over time. These are often sought after for chemical retro-bright whitening restorations.
Key Features & Core Technology

The watch is famous for trying to compress early health-tracking technology into a standard digital watch frame:
  • Dual-Sensor Pulse Monitoring: Unlike modern smartwatches that use optical sensors solely on the wrist, the BP-100 utilizes a two-step process. It has an optical photo sensor on the front plate (where you rest your index finger) and a metal contact sensor on the backplate resting against your wrist. It calculates blood pressure by measuring the pulse wave velocity between those two points.
  • Data Logging: The watch can store up to 30 individual blood pressure and heart rate logs directly into its built-in memory, alongside basic biometric data.
  • Standard Features: Beyond its health sensors, it operates as a full-featured digital watch of its era, containing a 1/100th-second stopwatch, countdown timer, dual daily alarms, and a standard microlight.
