Casio G-SHOCK GM-2100M-1AJF Analog-Digital Watch
The Casio G-SHOCK GM-2100M-1AJF is a metal-covered model from the G-SHOCK 2100 Series, featuring a modern industrial design in black and silver. It combines an octagonal stainless-steel bezel with G-SHOCK shock resistance and 20-bar water resistance.
The watch uses Casio module 5611, a quartz analog-digital movement with a black digital display, red functional markings, and a double LED Super Illuminator. Its inorganic glass, resin case, stainless-steel bezel, and textured biomass-resin band provide a practical and distinctive everyday configuration.
The bezel features a checkering pattern and openings that reveal the glass-fiber-reinforced resin center case. Functions include world time, stopwatch, countdown timer, five daily alarms, full auto-calendar, and a hand-shift function for improved digital-display visibility.
