Stepping up in the same dial colour
The A700 series is Casio's answer to the calculator-watch aesthetic of the late 1970s and early 1980s, stripped back to its essentials and pressed into a stainless steel case that sits just 6mm from the wrist. At that thickness it is closer to a bracelet than a watch in profile, and it disappears under a shirt cuff in a way that chunkier digital watches simply cannot manage. The mesh bracelet is the right choice for this format. It adjusts by sliding the folding clasp along the band rather than extracting links, which means sizing takes seconds and fits anyone between wrist sizes without visiting a jeweller. On the wrist, silver on silver reads as a single continuous object — the 35.5mm rectangular case flows into the bracelet without a visual break. The backlight is amber rather than green, which suits the warm metallic finish better than the cold glow found on most digital watches. Battery life runs to around three years on a CR1616, which is the kind of figure that makes the watch easy to forget about in the best possible sense.

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?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Will the glass scratch?
Yes, but it polishes out. Acrylic marks easily and a scratch can be buffed away at home, which is why vintage-style watches still use it.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
What size strap does it take?
18mm. 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.
Will it fit my wrist?
Lug-to-lug is 37.4mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
