Casio Full Metal 5000 Series 43.6mm Mens Watch Silver
Ref. GMW-BZ5000D-1ER
Sits in Casio’s upper tier here — more premium than three quarters of the Casio watches we list, which start at £25.
Price range £25 to £919 across 170 Casio watches in stock.The GMW-BZ5000D sits at the end of a lineage that begins with the original square G-Shock of 1983. Where that first model was a plastic tool built to survive a drop, this iteration rebuilds the same octagonal silhouette entirely in stainless steel, with the resin shock absorber retained inside the case so the toughness is preserved even as the exterior becomes something considerably harder to ignore. It is the BZ5000 generation's main distinction from its predecessor: Bluetooth synchronisation added alongside the existing six-band radio reception, so the time can be corrected either automatically from a terrestrial signal or manually through the Casio app, whichever the wearer finds useful. At 172 grams on the wrist, it announces itself immediately, and the 49.3mm lug-to-lug measurement means it sits large. The MIP display is the right choice for a screen this size — readable at an angle, readable in direct sun, and capable of rendering the retro layout that recalls the 1983 original for those who want it. The solar cell can run the module for six months in darkness on a full charge, or stretch to 22 months in power-saving mode, which means managing the battery is essentially not a consideration.

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?
No. It charges from light, and the cell behind that is designed to last a decade or more.
Will it fit my wrist?
Lug-to-lug is 49.3mm, 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.
