Casio G-SHOCK GMW-B5000D-1ER Full Metal Solar Bluetooth Watch - W17646
Ref. GMW-B5000D-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 129 Casio watches in stock.The square case that started G-Shock in 1983 was always resin — tough, light, deliberately rough around the edges. The GMW-B5000 takes that same geometry and rebuilds it in stainless steel, which required a genuine engineering solution: shock resistance in an all-metal case is achieved by fitting fine resin cushioning between the bezel and the case beneath it, so the structure absorbs impact without growing to accommodate it. The result weighs 167g and reads as a serious industrial object rather than a sport toy, while remaining unmistakably the DW-5000C's descendant. On the wrist it is a dense, considered thing — the dimple-processed bracelet mirrors the texture of the original rubber band, which is a quiet piece of continuity most wearers will not immediately place. The DLC-treated screw-back resists scratching in a way the front will not, which is an honest set of priorities for a watch used hard. Radio synchronisation across six stations worldwide, Bluetooth pairing for time correction wherever signals do not reach, and solar charging together make manual time-setting essentially irrelevant for daily wear.

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.
