Stepping up in Casio's range
An octagonal utility bezel frames the matte military green case, which is built around a Carbon Core Guard structure using carbon-reinforced resin. At 48.5 × 45.4 × 11.8 mm and roughly 51 grams, it sits broad but light on the wrist. The analogue-digital dial pairs a green face with Neobrite-treated hands and indices, backed by hard mineral glass. The green resin band fits wrists from 145 to 215 mm. Functions include world time across 31 zones, a 1/100-second chronograph, countdown timer, five daily alarms, and a hand-shift feature that clears the analogue display for unobstructed LCD reading. Water resistance is rated to 200 metres.

Learn more about Casio
Tadao Kashio founded Kashio Seisakujo in Tokyo in 1946 as a machine shop. The company's first success was a finger ring that held a cigarette, and its second was the 14-A of 1957 — the world's first all-electric compact calculator, which used solenoids rather than gears.
Casio entered watchmaking in 1974 with the Casiotron, a digital watch with an automatic calendar that knew the varying lengths of months. The company approached watches as an electronics manufacturer rather than a horological one, and that difference produced the G-Shock.
The G-Shock came from a single engineer, Kikuo Ibe, who broke a watch his father had given him and set out to build one that could not break. The specification was three tens: survive a ten-metre drop, ten bars of water pressure, and ten years of battery life. It took over two hundred prototypes, and the solution was suspending the module inside the case on a cushioned internal structure rather than mounting it rigidly. The DW-5000C shipped in 1983.
It became one of the most durable product designs in any category, adopted by militaries, emergency services, and skateboarders alike, and Casio has since added solar charging, radio and GPS timekeeping, Bluetooth, and full-metal and carbon variants.
Casio also produces the Edifice, Pro Trek, and Oceanus lines, and remains an independent Japanese public company.

It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?

Listed as men's.
