Popular "CasiOak" now also in an all-steel version with solar power and the option of connecting to a phone via Bluetooth.
Casio G-Shock GM-B2100BD-1AER are a men’s sports model, bringing the popular design in the proven octagonal case already used on the legendary Casio G-Shock DW 5000C model, now in an improved all-steel version, with a solar-powered movement and the option of connecting to a mobile phone via Bluetooth. The G-Shock range has been offering durable watches with a large number of functions in a practical and timeless design for 35 years.
Casio G-Shock GM B2100BD-1A comes, as we are used to with the range, with workmanship thanks to which the watch will withstand exposure to demanding conditions.
The watch has a combined black dial. They place emphasis on good legibility and easy operation to allow full use of all the functions they offer. Among the most important is undoubtedly the option to synchronise the watch with a smartphone via Bluetooth technology. The connection, in conjunction with the use of the relevant mobile application (CASIO WATCHES), makes it possible to keep constantly up-to-date and accurate time under control, offers the option of easy watch settings, and offers world time, date, day of the week, stopwatch, alarm and many other functions that you will use during sport and leisure time.
The durable steel case of the watch is complemented by a steel strap, both with a black IP surface treatment. A special surface treatment using the DLC method was used on the case back, ensuring even higher durability. The dial is protected by a mineral crystal. For easy readability in poorer light conditions, the watch is equipped with hands with a luminescent layer and double LED lighting, which, after pressing a button, illuminates both the analogue and digital part of the dial. At the 9 o’clock position there is a sub-dial showing the currently used mode, the digital display shows data related to the selected mode. Thanks to the solar drive, in which the watch battery is charged by natural and artificial light, the need for regular battery replacement is eliminated; the battery life is around 7 - 10 years. The case diameter of 44,4 mm places the model among larger watches. The water resistance of this model is 200 m, so you can swim with the watch without any problems.
The Casio G-Shock model range offers suitable watches for anyone looking for a combination of durable, sports watches in an attractive design, together with a rich range of functions. All models from this globally popular range are more resistant to shocks and impacts compared to ordinary watches. They also demonstrate increased resistance to magnetic fields.

Casio, Japan is one of the best-selling watch brands in the world. The first watches from the Casia workshop were digital and at the same time the first in the world to display the date. Casio's digital watches are no longer popular today, although analog watches or watches with a combined time display already form a large part of the range.
Casio has made history with its range of super-durable G-Shock watches, which are equipped with a light but sufficiently durable construction (against falls of up to 10 m, shocks, vibrations, magnetic field and temperature fluctuations) and a great value for money. The glory of the G-Shock watch over time also required a lightweight women's version - Baby-G. The Casio Pro Trek or Casio Edifice outdoor watches are also very popular. Casio does not lag behind in modern technology either, as evidenced by models equipped with Bluetooth technology, the Tough Solar solar drive or the high-precision radio-controlled Wave Ceptor watch.
Helveti.eu is an authorized dealer and specialist of the Casio brand.
