The Casio Tactical G-Shock GD-010 Series Black & Red Collection Digital Watch pairs a bold blacked-out exterior with a high-saturation red LCD for stronger visual contrast and everyday toughness. Its large-case design uses bio-based carbon and resin materials with Carbon Core Guard structure, backed by shock resistance, 200 m water resistance, mineral glass, and an approximate 10-year battery life on CR2025 power. This digital model includes Multi Time for 4 cities, world time across 31 time zones and 48 cities plus UTC, a 1/100-second stopwatch, 24-hour countdown timer, 5 alarms, hourly signal, Super Illuminator LED backlight, and a full auto-calendar through 2099.
