Stepping up in the same dial colour
Built around a full-resin construction — case, bezel, and band — the GBD-200 sits at 48.4 × 45.9 × 15.0 mm and weighs 58 grams. The black MIP LCD dial offers high-contrast readability in bright conditions, with a fully customisable training screen layout. A high-luminance LED backlight with auto-light switching handles low-light use. Shock-resistant and water-resistant to 200 metres, the watch pairs via Bluetooth to sync time automatically and pull world time data for around 300 cities. The built-in accelerometer tracks steps, distance, speed, and pace, while the interval timer supports up to five countdown settings. Battery life runs approximately two years from a single CR2032 cell.

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.
