Product Details

Description

The Casio G-Shock GM-S2100BC-1AER combines the legendary toughness of the G-Shock line with a refined, feminine aesthetic. Thanks to advanced forging technology, the ion-plated bezel shines in bright yellow gold with a distinctive wave-relief pattern — a subtle yet extraordinary detail. The contrasting black resin strap lends this watch an effortless elegance that complements any style.

The resin and stainless steel case houses a high-quality mineral glass and a combined analog-digital display. The analog hour and minute hands sweep every 20 seconds to reveal the digital display beneath. With shock resistance and water resistance to 20 bar, the GM-S2100BC-1AER is fully equipped for everyday wear. Neobrite luminous coating ensures excellent legibility even in the dark.
