Up for sale is an extremely rare vintage Casio GM-10 men’s digital game watch, produced for the Japan Domestic Market (JDM) during the 1980s and powered by Module 165. This iconic model is part of Casio’s early game watch lineup, combining classic digital timekeeping with an integrated interactive game display, making it one of the more distinctive and collectible pieces from the brand’s golden era.
The watch is in full working condition, and all features and functions are operating properly, including timekeeping, game mode, and all button functions. The display is clean and clear with no signs of screen bleed.
The watch is fitted on an aftermarket strap that suits the watch well. A small shim is present internally where the top right pusher engages the module. This was not a repair performed by me, and it is unclear whether it is necessary; however, the watch functions properly with no issues in use.
The watch is in good physical condition, showing signs of use and age consistent with a worn vintage watch. The photos best describe its overall appearance and should be reviewed carefully.
This is an iconic and extremely rare Casio model, especially difficult to find in working condition, making it a standout addition for collectors of vintage digital and Casio game watches.

► 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.
