Overview

This is a classic piece of 'wrist-top' computing from the 1990s, featuring a multi-lingual data bank and a full membrane keypad. It represents the pinnacle of pre-smartphone utility, designed to store phone numbers, schedules, and perform calculations on the fly.

Story

In the 1990s, this wasn't just a watch; it was a status symbol for the tech-savvy professional. Before the iPhone, having your entire contact list on your wrist felt like living in the future. It was the ultimate nerd-chic accessory.

Maker / Origin

Casio revolutionized the watch industry by treating timepieces as wearable computers rather than just mechanical tools. Founded by Tadao Kashio, the company transitioned from making mechanical calculators to digital icons, defining the aesthetic of the 80s and 90s.

Condition & Value

The watch appears functional with a clear display, though there is visible wear on the keypad's bottom right corner and some surface scuffing on the resin case. This honest wear suggests it was a daily companion, which slightly lowers the value compared to a 'New Old Stock' example.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
