Product Details
Description
The Casio G-Shock Pro GST-B100-1AER is a rugged men's wristwatch from the G-STEEL line, combining bold design with cutting-edge functionality. Its resin and stainless steel case featuring a Layer Guard structure reliably protects the inner workings, while the rotating disc dial at 9 o'clock — inspired by jet engine turbine blades — gives the model its unmistakable character. A battery indicator is visible through the gap between the disc blades.
The watch is powered by the Tough Solar system, which converts both natural and artificial light into stable energy, ensuring a reliable power supply even for energy-intensive functions. Via Bluetooth, the GST-B100-1AER connects to your smartphone and automatically synchronises the time. Additional practical features include dual world time display, stopwatch, countdown timer, daily alarm, and a bright LED backlight (Super Illuminator). The mineral glass and screw-lock crown complete the professional appearance.
