Stepping up in the same colour and case shape
A large resin case — 49.6 mm long, 47.8 mm wide and 15.7 mm thick — gives this G-Shock a substantial presence on the wrist, though at 65 grams the all-black build wears lighter than it looks. The dial pairs analogue hour and minute hands with a negative LCD panel in the lower portion, keeping the dual-time readout clearly separated from the main timekeeping. Neobrite lume coats the hands, and an electroluminescent backlight illuminates the digital section in low light. The mineral crystal sits above, while a black resin strap with a buckle clasp secures the watch comfortably. Water resistance reaches 200 metres, and the structure is both shock and magnetically resistant to ISO 764.

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.
