Up for sale is an extremely rare vintage Casio Rookie Adventure Club RKA-506 men’s flip-top ana-digi watch, powered by Module 358 and produced for the Japan Domestic Market (JDM) in the 1980s. This is one of Casio’s most unique hybrid designs from the era, featuring a flip-top cover that opens to reveal an analog dial with a digital display tucked below — a signature feature of the Adventure Club lineup.
The watch is in full working condition, and all features and functions operate properly, including the analog timekeeping, digital display, and mode functions. It is currently fitted on an aftermarket black leather strap and all other parts of the watch are original.
The watch is in good physical condition, but shows signs of use and age consistent with a vintage worn item. The photos best described its physical condition.

► 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.
