Stepping up in Casio's range
The GBD-200 takes the original square G-Shock silhouette and turns it toward running without losing the toughness that defines the line. The accelerometer inside tracks pace and step count directly on the wrist, and a Bluetooth link to the G-SHOCK MOVE app lets it cross-reference phone GPS data to sharpen distance calculations — a practical solution given there is no internal GPS to drain the battery. At 58 grams it is strikingly light for a G-Shock, and the slimmed-down profile sits far closer to the wrist than the chunky reputation of the range might suggest. The khaki-grey palette is deliberately urban rather than tactical, and the MIP display is worth noting: unlike standard negative LCD screens it remains fully legible in direct sunlight, which matters when you are mid-run and checking your split. The ventilated strap aids breathability, though its angled lug architecture means it is not interchangeable with standard aftermarket straps. What reads as a backlight button on the front face also doubles as wrist-tilt activation for the Super Illuminator — the watch has no luminous paint, so night legibility depends entirely on that LED system, which proves bright enough that the absence of traditional lume is rarely felt.

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.
Will the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Is it a men's or women's watch?
Listed as men's.
