Description
The Casio G-Shock GBM-2100A-4BER is a versatile men's watch that combines rugged outdoor durability with a refined business aesthetic. The high-contrast burgundy dial ensures excellent legibility, while the distinctive stainless steel bezel lends the case a sophisticated touch. The case, bezel and strap are crafted from carefully selected bio-based resin, uniting eco-conscious material choices with proven G-Shock toughness.
The reliable Tough Solar charging system powers the watch via light for continuous operation. Through the Smartphone Link function via Bluetooth, the GBM-2100A-4BER connects to the CASIO WATCHES App and automatically sets the time based on approximately 300 world time cities. A stopwatch, countdown timer, 5 daily alarms and world time across 38 time zones make it a feature-rich companion for everyday life and travel. The analog-digital display with dual LED illumination (Super Illuminator with Neobrite) ensures excellent visibility even in the dark. Water resistance to 20 bar guarantees outstanding resilience.
