Casio G-SHOCK GA-B010-1AJF Men's Watch Black

The GA-B010-1AJF is a modern G-SHOCK designed for everyday durability and smart functionality. Featuring a bold big-case design with an easy-to-read analog-digital display, this model combines rugged performance with practical lifestyle tracking.

Powered entirely by Tough Solar technology, the watch supports step tracking without the need for battery replacements. A newly developed low-power module and optimized algorithm reduce energy consumption, enabling efficient step counting and display using only solar energy.

The design incorporates a metallic-finished ring bezel, sunray dial, and metallic inner dial accents, delivering a refined yet sporty look that suits both casual and work styles. Large front buttons and a high-brightness double LED light ensure excellent usability and visibility, even in low-light conditions.

Bluetooth® connectivity allows seamless pairing with the CASIO WATCHES app, providing automatic time updates and enhanced functionality. Biomass plastics are used in key resin components, supporting a more environmentally conscious design.
