Product Overview

The G-Shock Men’s Tough Solar Black Resin Sport Watch is built for those who demand uncompromising durability and reliability in extreme conditions. Designed for military personnel, law enforcement officers, surfers, and outdoor enthusiasts, this watch delivers consistent performance where ordinary timepieces fail. Powered by an advanced solar-recharging system, it maintains operation using ambient light—even from fluorescent sources—eliminating the need for frequent battery changes. Its shock-resistant construction and 20-bar water resistance make it ideal for demanding environments, from rocky trails to deep-water activities. Whether you’re navigating rough terrain or braving the elements at sea, this watch is engineered to keep running when it matters most.

Key Features

• Shock Resistance: Engineered with a rugged internal structure that absorbs impacts and resists damage from drops, bumps, and vibrations. This makes the watch highly reliable during high-activity use such as hiking, climbing, or tactical operations.
• Solar Power System: Casio’s solar-recharging technology converts both natural and artificial light—including faint indoor lighting—into energy, ensuring continuous operation without battery replacements under normal use conditions.
• 20-Bar Water Resistance: Rated for depths up to 200 meters, this watch is suitable for swimming, snorkeling, surfing, and other water sports. It can also withstand daily exposure to water, including handwashing and showering.
• EL Backlight: Features an electroluminescent backlight that illuminates the watch face in low-light or dark environments, allowing for clear time reading at night or in dimly lit spaces.
• Durable Resin Band and Case: The black resin construction provides lightweight comfort while maintaining exceptional toughness against wear and tear in harsh conditions.
