Today, Casio G-SHOCK unveiled its latest Bluetooth connected models with the new BLE Connected G-STEEL.

Designed to feature a new layer guard case structure that is slimmer than previous G-STEEL watches, the new connected timepieces represent the top range of the G-STEEL line. The new models will be available in silver stainless steel (GSTB100D-1A), black resin with a silver stainless steel bezel (GSTSB100-1A), and a special edition black resin with a black, carbon fiber bezel (GSTB100X-1A).

Each BLE Connected G-STEEL model utilizes Bluetooth low energy technology to pair with smart phones via the G-SHOCK connected app, giving the user the ability to use the Phone Finder feature, change time zones, check the battery level, and set a timer or alarm from the app. Each watch also features solar-powered charging capabilities, a new functional face design with a "turbine inspired" level indicator disc and a super LED light for maximum visibility.

In addition, the special edition GSTB100X-1A will offer premium features such as a sapphire crystal, as well as a neo-matte black coating on the metal band loop and forged buckle. This particular model also boasts a Nanoalloy bezel, which is specially molded with 40 layers of carbon sheets to create a unique light weight, shock resist structure.

Each model also comes equipped with standard G-SHOCK technology of shock resistance and 200M water resistance, as well as neo-brite luminous hands, world time / dual time display, daily alarm, stopwatch, countdown timer, date display and a full auto calendar -- all in a 53.8mm case.
