Casio Full Metal 5000 Series 43.6mm Mens Watch Gold
Ref. GMW-BZ5000GD-9ER
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 £799 across 128 Casio watches in stock.The original G-Shock square — the DW-5000 from 1983 — was a plastic watch built to survive being dropped. The GMW-BZ5000GD-9ER is what happens when that same case geometry is remade entirely in stainless steel and finished in gold ion plating: same silhouette, substantially different proposition. The resin shock absorber sits inside now, hidden behind metal on every surface, and the screw-lock caseback seals it to 200 metres. At 172 grams on the wrist, it is a deliberate presence. The MIP display rewards the weight — eight selectable layouts mean the dial can read as a clean seven-segment classic or a denser informational screen depending on mood, and the Super Illuminator makes either legible in the dark without hunting for the button. Timekeeping resolves itself through Multi-Band 6 radio reception or the Bluetooth link to Casio's app, whichever signal finds it first, pulling from a pool of around 300 city presets. The solar cell keeps the whole system running indefinitely in normal use, or holds charge for up to 22 months in Power Saving mode if the watch is put away.

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.
