Discover the Casio G-Shock GA-2100-7A7, part of the acclaimed Tone-on-Tone series that reimagines the iconic "CasiOak" silhouette in a clean, monochromatic white finish. The case and bezel are crafted from carbon and bio-based resin with Casio's Carbon Core Guard structure, delivering serious shock resistance in a shape that measures 48.5 x 45.4 x 11.8 mm and weighs just 51 grams for comfortable all-day wear. A mineral glass crystal protects the analog-digital display, which includes a hand-shift feature so the digital readout is never blocked by the hands. Built for real-world use, this watch offers 200-meter water resistance, a double LED Super Illuminator light for visibility after dark, world time across 31 time zones, a 1/100-second stopwatch, a 24-hour countdown timer, five daily alarms with hourly time signal, and a full auto-calendar programmed through the year 2099. With a battery life of approximately three years and accuracy within ±15 seconds per month, the GA-2100-7A7 combines dependable performance with the versatile, street-ready style G-Shock is known for.
