Casio G-Shock GR-B300-1AER GravityMaster Mens Watch

The Casio GRAVITYMASTER GR-B300 from the renowned G-SHOCK "Master of G" series is a watch that has been specially developed for demanding situations and extreme conditions. Inspired by aviation, the watch combines innovative technologies, robust materials and a variety of functions that make it an indispensable companion for professionals and adventurers.
The GR-B300 is characterised by its Carbon Core Guard construction, which ensures shock resistance, rigidity and corrosion resistance. This technology, originally used in aircraft construction, gives the watch its exceptional durability. The case is made of carbon fibre-reinforced plastic, which is not only extremely resistant but also lightweight. The seamless bezel, inspired by modern aeroplanes, contributes to the striking and powerful appearance of the watch and effectively protects the movement from shocks and external influences.

The GR-B300 offers a variety of functions that are specially tailored to the needs of pilots and frequent travellers. With the flight log memory function, users can record their current location and time and simultaneously display the time in two different time zones. This enables simple and intuitive operation, especially when travelling internationally, where a quick change between home and local time is required. The large indexes and metal bezel significantly improve readability, which is crucial in aviation. Pilots need to be able to read the time quickly and accurately, and the GR-B300 fulfils this requirement with flying colours.

The design of the GR-B300 is both functional and aesthetically pleasing. The rotating disc at 9 o'clock indicates the alarm status, stopwatch and battery status and gives the watch a modern, technical look. The black and white colour scheme with subtle colour accents is reminiscent of an aircraft cockpit and underlines the aeronautical inspiration of the watch.
Another notable feature is the use of bio-based resin for the main components of the case, bezel and bracelet. These eco-friendly materials help reduce the environmental impact and demonstrate Casio's commitment to sustainability. The technical specifications of the GR-B300 are impressive and offer everything you would expect from a high-quality G-SHOCK watch. With a case size of 59 × 54.7 × 15.7 mm and a weight of only 71 g, the watch is surprisingly light and comfortable to wear despite its robustness. The watch is shock-resistant and features the proven Carbon Core Guard structure for added durability.

The GR-B300 is water-resistant to 20 bar, making it suitable for all water sports. It is powered by Tough Solar technology, which provides a reliable and environmentally friendly source of energy. Thanks to Bluetooth® connectivity, the watch can be connected to a smartphone and automatically adjust the time to ensure accurate timekeeping.
The Bluetooth® function of the GR-B300 enables wireless connection to the CASIO WATCHES app, which offers a variety of useful functions. The app enables automatic time adjustment, simple watch settings and access to around 300 time zones worldwide. In addition, the app offers a flight log function and a phone finder, which can be used to quickly find a misplaced smartphone.
