The Casio G-Shock GST-B1000D-1AER adds a model to the G-Steel range that continues the tradition of durable G-Shock watches while taking it in a modern, minimalist direction. Its high durability is supported by the proven Carbon Core Guard construction. It also features a solar-powered movement and can be connected to a phone via Bluetooth.
The watch features a more sharply shaped case and a clean bezel line, now without a logo for a modern appearance. The case shape and dial details incorporate elements of the legendary DW-5000C, the first G-Shock. These include a brick wall motif and colour accents. Red symbolises the courage to face challenges, blue water resistance and yellow exceptional shock resistance.
The Casio G-Shock GST B1000D-1A has a clear analogue dial displaying the date, day of the week, stopwatch, alarm and other functions for sport and everyday wear. The dial has only two subdials. At 3 o'clock is a 24-hour time display, while the subdial at 8 o'clock displays the current day in the standard mode, or the selected mode or values when using the stopwatch and countdown timer. The dial is protected by a mineral crystal.
Luminescence on the hands improves readability in low-light conditions. The watch also has LED illumination for the display.
The case's high durability is ensured by a combination of a metal exterior and an internal Carbon Core Guard structure. The inner case is made of resin reinforced with carbon fibres, allowing the case height to be reduced. This combination creates a more compact and lighter watch. The case is fitted with a steel strap.
The case diameter of 44,2 mm places the Casio GST-B1000D-1AER among large watches. Water resistance of 200 m allows swimming and use during various more demanding activities.
A key feature of the watch is its solar power, which eliminates the need for regular battery replacement. The rechargeable battery is charged by natural and artificial light and has a lifespan of around 7 - 10 years.
The watch can also be synchronised with a smartphone using Bluetooth and the CASIO WATCHES app. Once connected, you can easily synchronise the time, set world time (by selecting 1 of more than 300 cities), the alarm and countdown timers, or correct the hand positions.
Other useful functions include Phone finder – pressing a button on the watch makes your phone ring, making it easier to find.
The Casio G-Shock range offers watches for anyone looking for a combination of durable sports watches in an attractive design and 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.
Helveti.eu is an authorized dealer and specialist of the Casio brand.
