Casio G-SHOCK GMC-2500-1AER G-Steel Black Resin Strap Watch - W17617
Ref. GMC-2500-1AER
Sits in Casio’s upper tier here — more premium than three quarters of the Casio watches we list, which start at £20.
Price range £20 to £919 across 152 Casio watches in stock.The GMC-2500 is G-Shock's first purely analogue reinterpretation of the DW-5000C, the original 1983 model that started the line. Where that watch was resin through and through, this one wraps a bio-based resin core in a stainless steel bezel, keeping the octagonal silhouette that collectors call the CasioNaut shape while producing something that sits at 68 g on the wrist — lighter than the construction suggests. The engineering underneath is worth understanding. The minute hand is held magnetically rather than fixed to the shaft, so a heavy impact deflects it and lets it return, rather than bending it. The small seconds subdial can be stopped entirely to push the battery life well beyond the standard two-year estimate. The matte black dial keeps the three-cell date wheel the same colour as the background, so it reads as texture rather than interruption, and Neobrite goes on the hands only — the amber backlight with afterglow handles the rest in the dark. At 46.7 mm lug-to-lug it wears more compactly than most G-Shocks of this rating, and the integrated lug design means the strap sits flush rather than hanging off the case in the usual way.

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?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat 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 46.7mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
