Casio G-SHOCK GM-2100BM-1AJF Analog-Digital Watch Black Dial
Casio G-SHOCK GM-2100BM-1AJF
The Casio G-SHOCK GM-2100BM-1AJF is part of the 2100 Series, combining an analog-digital display with a stainless-steel metal-covered bezel and G-SHOCK shock-resistant construction. This Casio quartz watch features a monochrome black and gray design with an industrial-inspired finish.
The watch is powered by Casio module 5611 and uses a resin case with a stainless-steel bezel, mineral glass, and a black resin band incorporating biomass plastic. The octagonal bezel features a textured checkering pattern, selected black ion-plated surfaces, and openings that reveal the glass-fiber-reinforced resin inner case.
Functions include world time, a 1/100-second stopwatch, 24-hour countdown timer, five daily alarms, double LED illumination, full auto-calendar through 2099, and a hand-shift function. Water resistance is rated at 20 bar, while the two SR726W batteries provide approximately three years of operation.
