Casio Edifice EFK-200D-4AER Auto Red Electroform Dial Bracelet Watch - W17598
Ref. EFK-200D-4AER
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 EFK-200D sits at an interesting angle within the Edifice range, which built its reputation on large, function-dense quartz chronographs with motorsport branding. This model steps away from all of that: no pusher crowns, no tachymetre ring, no digital complications. Just a self-winding mechanical movement — almost certainly a Miyota, hacking and hand-windable at 21,600vph — inside a 38mm case that fits a cuff without a fight. The dial is the reason to choose this one over its siblings. The electroforming process used to create it builds the surface layer by layer, producing a red gradation with visible depth rather than a flat colour. Under different light it shifts considerably, which makes the 11.9mm case thickness easy to forgive — at that dimension it is genuinely slim for something housing a rotor assembly, and it closes on the wrist at 43.6mm lug-to-lug in a way a chunky sports watch simply cannot. The bracelet alternates brushed and mirrored surfaces along each link, and the caseback is exhibition glass over the movement rather than a blank steel lid. Forty-two hours of power reserve is adequate for a weekend off the wrist, and the watch will wind itself again by Monday without a second thought.

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 100m it is rated for swimming and snorkelling, though not for diving.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Will it fit my wrist?
Lug-to-lug is 43.6mm, which suits wrists from roughly 15cm (6 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, though at 38mm it sits in the range that suits anyone.
