Product Details
Description
The Casio G-Shock G-Steel GM-2100YMG-9AER from the Fine Metallic Series combines the iconic octagonal bezel of the GM-2100 family with a monochrome gold-tone aesthetic. The glass-fibre reinforced resin case is crowned by a gold-tone ion-plated stainless steel bezel, crafted through an elaborate forging, cutting and polishing process. The robust silicone strap is finished with a vapour-deposited urethane layer that creates a metallic shimmer while ensuring comfortable wear.
The watch combines analogue and digital timekeeping: two analogue hands for hours and minutes alongside a digital display featuring world time (31 time zones), stopwatch, countdown timer and a fully automatic calendar until 2099 make it a versatile companion. Thanks to shock resistance and water resistance to 20 bar, the GM-2100YMG-9AER is built for demanding conditions. The dual LED illumination (Super Illuminator) ensures excellent legibility even in darkness.
