The GA-B010 sits at the point where G-Shock's familiar ana-digi format meets the kind of connectivity that used to require a separate device. It draws on the compact geometry the GA-2100 established but adds solar charging, Bluetooth sync, and a built-in step counter — making it less a tool watch with smart features bolted on and more a considered rethink of what a daily-wear G-Shock can do without a battery change in sight. Tough Solar modules have a strong track record for longevity, and the combination of that system with Bluetooth timekeeping correction means the watch largely runs itself. At 57 grams, it sits on the wrist with considerably less presence than the 49.3mm footprint suggests. The matte olive-green resin reads as deliberately muted — closer to field equipment than sportswear — while the vapour-deposited bezel ring and sunray dial texture introduce a degree of surface interest that keeps it from feeling purely functional. Dual LED illumination covers both the analogue and digital sections independently, so the watch is fully legible in the dark without relying on lume alone.

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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Will it fit my wrist?
Lug-to-lug is 52.3mm, which suits wrists from roughly 17.5cm (7 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's.
