Casio G-Shock GST-B100 Series

Perhaps the most popular and technological steel jishoks from the G-Steel line. The case is partially made of stainless steel with polyurethane inserts – now even stronger. In addition to the shockproof housing design, the module is protected from vibration by alphaGel shock-absorbing material. The design of the dial is very similar to the theme of aviation – the window at around 9 o’clock rotates like an airplane’s turbine, and both other windows look like instruments in the cockpit. The watch provides the ability to synchronize with a smartphone via Bluetooth – to configure functions and adjust the time. Pairing is done with just one click of a separate button. Do not worry about replacing the battery – the GST-B100 is powered by sunlight and daylight. The Smart Access crown allows intuitive and quick access to all watch functions.

Official Marketing Focus from Casio

From G-SHOCK, the watch that always strives for toughness, the first G-STEEL lineup models to offer chronograph performance in analog format.
Thought all the dials of these models are analog, they still boast G-SHOCK level shock resistance.
The dial at 9 o’clock has a multi-functional rotating disk that is cut to resemble the thick blades of a jet engine. Rotation of the blades reveals red coloring behind the disk, and this change in color is used to indicate the battery level and the alarm on/off setting. The blades also rotate in the Timekeeping and Stopwatch modes to with the passage of time.
A new layer guard structure houses resin cushioning parts inside the case, for a more elegant design and a better fit to the wrist. High density mounting technology makes it possible to create a module that is smaller and thinner, which also contributes to a better fit.
