► SELLER'S DESCRIPTION
Up for sale is an extremely rare vintage Casio GAME-20 GM-20 men’s digital game watch, powered by Module 165 and produced for the Japan Domestic Market (JDM) in the 1980s. Casio game watches from this era represent some of the brand’s most creative and desirable digital designs, combining classic timekeeping with built-in interactive gameplay that has made these models highly sought after by collectors worldwide.
The backlight is not working, and some pixels on the seconds counter portion of the display appears to be faded/missing, which can be seen in some of the photos. Beyond these issues the watch is in full working condition and all other features and functions of the watch are working properly. The module is completely screen-bleed free, which is exceptionally rare to find on vintage Casio game watches.
All parts of the watch are original, including the original Casio stainless steel bracelet.
The watch has visible signs of use and age, but the photos best describe its physical condition and should be reviewed carefully.
