The Casio GMQ-100 Moon Graph is an ultra-rare, vintage digital desk alarm clock released by Casio in 1985.
It was originally produced in very limited numbers, often distributed as a promotional companion piece alongside Casio's iconic astronomy-themed wristwatches of that era
Key Features & Design
- The LCD Display: It features a complex, retro-futuristic digital display that mimics Casio's astronomy watches. The screen includes an animated moon phase graphic, sun phases, and a background matrix complete with flashing decorative stars.
- Core Functions: It includes a standard time display (supporting 12 and 24-hour formats), a daily alarm, and a built-in digital stopwatch.
- Physical Layout: The clock is scaled up to function as a desk or bedside piece, but its internal programming and operational layout closely match a digital watch. It features four main adjustment buttons located on the reverse side of the casing for setting the time and toggling modes.
Collector Status
Today, the GMQ-100 is highly sought after by vintage tech and watch enthusiasts. Because it was sold in scarce quantities compared to standard Casio travel alarms, units in functional condition (especially "New Old Stock" with their original packaging) command a premium price on collector platforms.
It belongs to a rare trio of 1980s Casio graphic clocks, sitting alongside its sister models: the TGQ-200 (Tri-Graph) and the CGQ-300 (Cosmo Phase).
