About this watch
The Casio G-Shock GBM-2100A-4B puts the slim octagonal 2100 shape in a forged stainless-steel bezel with a circular hairline finish on top and mirror-polished sides. The burgundy dial carries a horizontal grid pattern applied with transparent printing and a metallic vapour-deposited texture, set off by silvery indexes, luminous hands and a compact digital display. A black bio-based resin strap keeps it light and comfortable, so it moves easily from weekend wear to the office.
Inside is Casio Module 5729 with Tough Solar charging and Bluetooth Smartphone Link through the CASIO WATCHES app, which sets the time automatically and adds around 300 world-time cities, a reminder and phone finder. Unlinked accuracy is ±15 seconds per month, and a full charge runs about 7 months in normal use without light. Functions include world time in 38 cities, a 1/100-second stopwatch, a countdown timer, 5 daily alarms, a full auto-calendar, a battery level indicator and a double LED light. The shock-resistant case measures 49.3 × 44.4 × 11.9 mm and weighs 72 g, with mineral glass and 200-meter (20 ATM) water resistance, suitable for swimming and snorkelling.
The Casio G-Shock GBM-2100A-4B offers solar power, phone-synced timekeeping and real G-Shock toughness in a dressier metal-bezel package, a strong choice for anyone who wants one watch for every day.
