Casio is a watch brand that combines toughness, functionality, and design. Its models appeal to adventurers, athletes, and anyone looking for a reliable everyday timepiece. Through its G-Shock line, Casio delivers ultra-rugged, feature-packed watches that meet every need and preference. Discover the Black On Black GD-010-1A1ER, designed for men's wrists. Finished in black, it features a case crafted from bio-based resin reinforced with carbon fiber. Built on a Carbon Core Guard structure, the case weighs 65 g and measures 52 mm in diameter, 55 mm in length, and 16.10 mm in thickness. A mineral crystal sits over the dial and its indicators. Five push-buttons on the sides of the case handle all function adjustments. Finally, this shock-resistant watch features a screw-secured case back providing water resistance to 20 ATM.
This striking black round dial is bordered by key model specifications. It features a digital display showing hours, minutes, seconds, alarms, day, date, and month, along with additional functions depending on the settings. The brand name appears at 12 o'clock.
At the heart of this watch beats a Japanese quartz movement. Made by Casio, it is powered by a battery with a lifespan of up to 10 years. This quality mechanism ensures high performance and accurate timekeeping in every situation.
This strap, crafted in bio-based resin, fits men's wrists with a circumference ranging from 145 to 215 mm. It fastens with a tang buckle for a secure, reliable hold. The strap delivers optimal comfort and works with a variety of styles thanks to its black color.
With water resistance rated at 20 atmospheres - equivalent to 200 meters - this model confidently earns the title of dive watch. Watch experts agree it's more than up to the task for showers, baths, intense swim sessions, freediving, and recreational scuba diving. That said, it is not intended for extreme deep-sea diving, where pressure would exceed its water-resistance limits. For professional divers pushing depth records, we recommend models rated at 30 ATM or higher. We also advise against operating the push-buttons or crown while submerged, to maintain a perfect seal at all times.
