Casio G-Shock GM-B2100VF-1ADR Porter Collaboration are a limited edition created in collaboration with the Porter brand and together they celebrate 40 years of G-Shock models on the market. The design of the octagonal case refers to the legendary Casio G-Shock DW 5000C. However, the current model is equipped with a solar-powered movement and the option of connecting to a mobile phone via Bluetooth.
Casio G-Shock GM-B2100VF-1ADR were created in collaboration with the Porter brand, a top Japanese bag manufacturer. Master craftsman Kichizo Yoshida founded YOSHIDA & Co. in 1935 and introduced the PORTER brand in 1962. With the company motto “heart and soul into every stitch”, PORTER continues to produce bags of exceptional workmanship made in Japan. The brand pays tribute to luggage carriers and reflects respect and dedication to the quality of products by true craftsmen.
The watch stands out mainly with its "used" look, which was achieved by applying a black IP surface treatment and then partially removing it, resulting in the special texture. The shade of the luminescence on the hands was also matched to the overall look. The logo on the case back designed by Eric Haze refers to the significant anniversary of the brand, while the folding buckle bears the Shock-Resist slogan indicating the high durability of the watch.
As part of this limited edition, Porter also introduced a unique collector's bag with an octagonal shape that reflects the design of the GM-B2100. This premium bag is made of densely woven water-repellent Ventile® fabric and has a leather tag marked G-SHOCK 40.
Casio G-Shock GM B2100VF-1A comes, as we are used to with the range, with workmanship thanks to which it can withstand exposure to demanding conditions. The watch has a combined black dial with distinctive coloured indices and hands. They emphasise good legibility and easy operation to allow full use of all the functions it offers. Among the most important is undoubtedly the option to synchronise the watch with a smartphone via Bluetooth technology. The connection, in conjunction with 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, which 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 that gives the impression of wear. A special surface treatment using the DLC method was used on the case back, ensuring even higher resistance. The dial is protected by a mineral crystal. For easy readability in poor lighting conditions, the watch is equipped with hands with a luminescent layer and double LED lighting, which at the press of 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 power, 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.

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.
