Stepping up in Casio's range
The MTP-E740 series takes its cues from the scarce 1970s Seiko Time Sonar chronographs — not by copying their mechanics, but by borrowing their most arresting visual trick. The dial is semi-transparent orange, and the day and date wheels sit fully exposed beneath it, so the calendar numerals appear to float behind a coloured screen. It reads as a multi-layered mechanical object despite running on a 5339 quartz module that asks for nothing beyond a new battery every three years. At 8.7mm thick and 45mm lug-to-lug, the case disappears under a cuff in a way a standard 39.8mm steel watch usually does not, and the 103g total weight means the bracelet contributes without loading the wrist. That bracelet is a three-link design mixing brushed and mirrored surfaces, closed by a push-button deployant with micro-adjust holes in the clasp — the kind of fit detail usually absent at this category of watch. The day wheel reads in either English or Spanish, flipped by the crown, which makes it genuinely useful rather than decorative.

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?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
20mm. 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 45mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 39.8mm it sits in the range that suits anyone.
