Stepping up in the same colour and case shape
A large-cased analog-digital G-Shock built around a Carbon Core Guard structure, giving the resin case genuine lightness despite its size — 51.2 × 47.0 × 14.1 mm and 64 grams on the wrist. The black and yellow colourway carries through the dial and resin strap, which fastens with a buckle and features a quick-release slide lever for strap changes. The mineral crystal is scratch-resistant, and a double LED Super Illuminator lights the display at the press of a dedicated button, while Neobrite coating covers the analogue hands. The hand-shift function moves the analogue hands clear of the digital screen when needed. Timekeeping runs via Module 5590, covering 31 time zones across 48 cities, with five daily alarms, a 1/100-second stopwatch, a 24-hour countdown timer, and an auto-calendar valid to 2099. 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.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 200m it is rated for swimming, snorkelling and recreational diving.
Water resistance explainedWill the glass scratch?
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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
24mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
