Watch GBM-2100A-8BER

The Watch

The Casio G-Shock watch, model GBM-2100A-8BER, is defined by its boldly modern and rugged design. The octagonal case commands attention with its construction in brushed steel, stainless steel, and polished steel, accented by black resin for a contemporary edge. This blend of materials delivers not only a striking aesthetic but also exceptional protection against impacts and scratches, ensuring long-lasting durability. Casio's watchmaking expertise is on full display with a weight of 72 grams, providing optimal wrist comfort despite the commanding dimensions of 49.30 mm in length, 44.50 mm in width, and 11.90 mm in thickness. True to G-Shock tradition, this watch delivers impressive resilience thanks to its screw-secured case back, which also contributes to its 20 ATM water resistance.

The Dial

The dial of the Casio G-Shock features a guilloché finish that adds depth and elegance. Its mineral glass crystal ensures exceptional clarity and effective scratch protection. Information is cleanly laid out with a combined analog and digital display for easy, at-a-glance reading of the hour, minutes, and seconds. The hands and indices are coated with Neobrite, delivering optimal legibility even in the dark, while the Super Illuminator provides a powerful, bright backlight. The dial also houses an LCD screen showing supplementary information such as the date and day. All these elements are harmoniously framed by a robust bezel and shielded by mineral glass for outstanding shock resistance.
