Stepping up in the same colour and case shape
The standout feature here is one that does not appear in any specification column: a vibration alarm. For anyone who needs a discreet alert — in a meeting, on a night shift, beside a sleeping partner — that silent pulse does a job no beep can, and it applies to the daily alarm, the countdown timer and the hourly signal alike. The ten-year battery life means the watch will run the better part of a decade before needing attention. At 47.1mm across it wears large, which suits the chunky resin construction, and at 50 grams it is light enough that it disappears on the wrist. The backlight is notably bright for this class of watch, with an afterglow that keeps the display readable after the button is released — useful when one hand is occupied.

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.
