Casio G-Shock G-Steel

Description

The Casio G-Shock GM-2100YM-8AER from the exclusive Fine Metallic Series combines indestructible G-Steel toughness with an elegant, monochrome silver design. The glass-fibre reinforced resin case is topped by a meticulously forged, cut and polished stainless steel bezel in the signature octagonal design. The bezel features distinct hairline and mirror-finish surfaces that create a premium metallic appearance. The silicone strap in a matching silver tone receives a shimmering metallic look through a vapour-deposited urethane coating, while remaining pleasantly soft and flexible to wear.

As an ana-digi watch, the GM-2100YM-8AER displays the time via two analogue hands as well as a digital display. Its extensive feature set includes world time across 31 time zones, a 1/100-second stopwatch, a countdown timer, five daily alarms and a fully automatic calendar valid until 2099. The dual LED illumination (Super Illuminator) ensures optimal legibility even in the dark. The watch is shock-resistant and water-resistant to 20 bar, making it a reliable companion for demanding situations.
