Casio G-Shock GM-B2100AD-5AER is a men's sports watch featuring the popular design in the proven octagonal case used on the legendary Casio G-Shock DW 5000C, now in an improved all-steel version, with a solar-powered movement and the option to connect to a mobile phone via Bluetooth. For 40 years, the G-Shock range has offered durable watches with a wide range of functions in a practical and timeless design.
As expected from the range, the Casio G-Shock GM B2100AD-5A is built to withstand exposure to demanding conditions.
The watch has a bronze analogue-digital dial. It is designed for clear readability and easy operation, allowing full use of all its functions. One of the most important is the ability to synchronise the watch with a smartphone via Bluetooth. Together with the relevant mobile app (CASIO WATCHES), the connection keeps the time accurate and up to date and makes it easy to set the watch, which offers world time, date, day of the week, stopwatch, alarm and many other functions for sport and leisure.
The durable steel case is complemented by a steel strap. The case back has a special DLC surface treatment for even greater durability. The dial is protected by a mineral crystal. For easy reading in low light, the watch has hands with a luminescent coating and double LED illumination, which lights up both the analogue and digital sections of the dial at the press of a button. A subdial at the nine o'clock position shows the current mode, while the digital display shows information related to the selected mode. Thanks to solar power, which recharges the watch's rechargeable battery using natural and artificial light, there is no need for regular battery replacement. The rechargeable battery lasts around 7 - 10 years. The case diameter of 44,4 mm places this model among larger watches. The model has a water resistance of 200 m, so it can be worn while swimming.
The Casio G-Shock range offers watches for anyone looking for a combination of durable sports watches in an attractive design with a wide range of functions. All models in this globally popular range are more resistant to shocks and impacts than ordinary watches. They also offer 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.
