The Edifice line has always sat at the intersection of office and outdoors — built for people who need timing functions that work, in something that can cross from a desk to a weekend without looking out of place. This particular variant, with its deep blue sunray dial, leans towards the dressy end of that range. At 11mm thick it sits flatter on the wrist than most chronographs of this footprint, and that matters more than the case diameter might suggest: it disappears under a cuff in a way that sporty watches rarely do. The three sub-dials are arranged cleanly enough that the face reads clearly at a glance rather than requiring a moment of orientation, and the brushed outer bezel, kept deliberately narrow, lets the dial claim most of the space. The bracelet adjusts on a pin-and-collar system — straightforward to size at home — and the deployment clasp releases with a single press rather than requiring two hands. At 128 grams the whole thing has enough presence on the wrist to feel considered without becoming fatiguing across a long day.

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?
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 48.6mm, which suits wrists from roughly 16.5cm (6½ 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.
