■ STATUS: SOLD
THIS TIMEPIECE HAS FOUND A NEW HOME
► SELLER'S DESCRIPTION
For sale is a rare vintage Casio TRI-20W Tri Sport Gauge men’s digital sports watch from 1986, powered by module 793. Designed specifically for triathletes, this model features Casio’s unique multi-sport interface with swim / bike / run tracking and a vibrant analog-style gauge display — a standout design from the golden age of 1980s digital innovation.
The watch is new old stock (NOS) without tags and has never been worn. All functions operate correctly, including the digital time display, stopwatch, and tri-sport gauge meter. The watch is in outstanding physical condition — near flawless — and the photos provide the best representation of its cosmetic state.
A clean aftermarket strap is currently installed, as the original factory strap naturally deteriorated over time. The original strap is included for display or restoration purposes and is shown in the photos.

► ARCHIVE FILE: CASIO — BRAND HISTORY
Casio began not with watches but with calculation. Tadao Kashio founded Kashio Seisakujo in Tokyo in 1946, and with his three brothers developed the 14-A in 1957, the world's first compact all-electric relay calculator, incorporating the business as Casio Computer Co. that same year. The move into watchmaking came in November 1974 with the Casiotron, a digital watch whose claim to fame was an automatic calendar that knew how many days each month had, a small feat of logic that announced how an electronics firm would approach timekeeping.
