Casio Edifice EFK-200DG-5AER Automatic Bracelet Watch - W17606
Ref. EFK-200DG-5AER
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-200 sits within Edifice's longer-running argument that a mechanical watch can wear like a dress piece without the fragility. The brown gradated dial is produced by electroforming and layered lacquering, a process borrowed from high-end automotive interiors that gives the surface a depth no printed dial achieves — it shifts under light in a way that reads differently at the desk than it does outside. The Miyota movement inside is a capable, widely trusted calibre running at 21,600vph with a hacking seconds hand for clean synchronisation, and the exhibition caseback means the owner gets to see it work. At 38mm across and 43.6mm lug to lug, it sits neatly on a mid-sized wrist without crowding it, and 11.9mm of thickness keeps it manageable under a shirt cuff. The H-link bracelet has its inner edges polished smooth, which matters on a watch this heavy — 153 grams is substantial, and the difference between rounded and square link edges becomes apparent by midday.

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.
