Stepping up in Casio's range
The EFR-S108D draws an obvious line back to the integrated-bracelet sports watches of the 1970s — the kind where case and bracelet read as a single architectural object rather than two separate components bolted together. At 39.9mm it sits at a size that works across most wrists without pressing the point, and 7.8mm thick is genuinely slim for a steel sports watch rated to 100 metres: it disappears under a shirt cuff where most watches in this category will not. The octagonal bezel with its brushed hairline finish carries that industrial aesthetic through to the dial, where the green is worked with a similar brushed treatment rather than left flat. In direct light the surface has some movement to it; in shade it reads as a clean, legible face. The lume on hands and indices is adequate for finding the time in a dark room but is not the heavy-duty compound found on dedicated dive watches, which is an honest reflection of what this watch is.

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 100m it is rated for swimming and snorkelling, though not for diving.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
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 44.8mm, which suits wrists from roughly 16cm (6¼ 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, though at 39.9mm it sits in the range that suits anyone.
