Casio G-SHOCK GST-B1000D-1AER G-Steel Solar Bracelet Watch - W17586
Ref. GST-B1000D-1AER
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 153 Casio watches in stock.The GST-B1000D-1AER traces its outline directly to the DW-5000C of 1983 — the octagonal bezel profile and the brick-patterned dial are both deliberate quotations from that first G-Shock — but it arrives with the logo stripped from the bezel entirely, a decision that reads as unusual restraint from a brand that rarely underplays itself. Three finishing techniques run across the case and bracelet: vertical hairline, circular hairline, and mirror polish, which means the watch reads differently depending on where the light comes from. What makes the proportions work is the Carbon Core Guard construction beneath the steel exterior. The stainless shell sits over a bio-based carbon-reinforced resin inner case, which keeps the total weight at 118 grams and the thickness at 11.6mm — compact enough for a watch carrying a perpetual calendar, GMT, chronograph, Bluetooth pairing and a power reserve that runs to five months on a full solar charge. The urethane buffers at the bracelet junctions do double duty, absorbing shock at the joints while taking some of the rigidity out of what would otherwise be an entirely hard-metal experience on the wrist.

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.
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?
No. It charges from light, and the cell behind that is designed to last a decade or more.
Quartz, automatic and solar comparedWhat size strap does it take?
14mm. 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 46.9mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
