Casio G-Shock GM-S2100GB-1AER is an addition to the popular "CasiOak" series, which is characterized by an octagonal case. Newly made of steel and with a smaller diameter.
The Casio G-Shock GM S2100GB-1A comes, as we have come to expect from the series, with workmanship that makes it stand up to exposure to harsh conditions. Even with the newly processed case, it loses none of its high durability (there is a metal case on the plastic base).
The watch has a combined (analogue and digital) dial that displays the date, day of the week, stopwatch, alarm and many other functions that you can use for sports and leisure.
The watch case is completed with a rubber strap, excellent for high durability and long life. Despite the materials used, the weight of the watch is at just 55 grams. The dial is protected by a mineral glass. For easy readability in low-light conditions, the watch is equipped with luminescent hands and dual LED illumination, which illuminates both the analogue and digital parts of the dial when the button is pressed. The digital display shows not only the selected mode, but also related data. The case diameter of 40.4 mm makes it one of the larger watches. The water resistance of this model is 200 m, so you can swim with the watch without any problems.
If you and your partner share a fondness for sports watches, it is possible to create a set in combination with the Casio G-Shock GM-2100G-1A9ER men's model, which will be a suitable gift for an anniversary or other unique occasions.
The Casio G-Shock model range offers a suitable watch for anyone looking for a combination of a durable, sporty watch in an attractive design, coupled with a wide range of features. All models in this globally popular range are more resistant to shocks and impacts than conventional watches. They also demonstrate increased resistance to magnetic fields.

G-Shock Unisex Watches CasiOak Watch gift for woman Casio Laides durable Watches
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.
