Stepping up in the same colour and case shape
The MDV-107D sits in a long line of Casio divers built around the Duro chassis — an unusually capable platform for the price bracket it has always occupied. This reference updates the formula quietly: the marlin logo that once decorated older Duro variants is gone, the licensing behind it having lapsed, leaving a cleaner dial that reads as more contemporary without altering the underlying architecture. The screw-down crown and solid caseback remain. On the wrist it wears considerably smaller than 46.3mm suggests, because that figure includes the crown guards; the bezel itself runs closer to 44mm, and at 12.1mm thick with a 49.5mm lug-to-lug span, it sits flat and close rather than proud. The unidirectional bezel turns with enough resistance to feel deliberate, and the bracelet's built-in micro-adjustment holes in the clasp housing mean fit can be dialled in without tools. The Neobrite lume on hands and indices charges quickly and gives useful initial legibility in darkness, though it fades faster than the material used on ISO-rated dive watches — honest enough performance for a watch at this level of the category, and no worse than most of its direct competition.

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.
What size strap does it take?
22mm. 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 49.5mm, 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.
