Men's Sport Watch Casio Gravitymaster GA-1000-1A with Temperature and Bearing Indication Black

Aviation Gravitymaster Series with Twin Sensor

This model belongs to the specialized G-Shock Aviation line and was developed considering the needs of pilots and extreme travel enthusiasts. The main feature of the device is the Twin Sensor technology, which combines a digital compass and a thermometer. The watch allows for instantaneous determination of direction and recording of the current bearing using the bearing memory function. This ensures reliable navigation even in conditions of limited visibility. The massive case with protective guards shields the internal mechanisms from vibrations, shocks, and centrifugal force.

Unique Lighting System and Data Visualization

An innovative Neon Illuminator lighting system is applied in the Casio GA-1000-1A. Unlike standard lamps, an ultraviolet LED is used here, which causes a special fluorescent coating on the hands and hour markers to glow. This creates a deep 3D effect and allows for reading the time in total darkness without blinding the eyes. The dial combines classic analog hands and two liquid crystal displays, which output stopwatch data, timer, world time, and sensor readings.

Functionality for Professional Use

The device is equipped with a full set of tools for monitoring time and the environment. The world time function allows for quick switching between 31 time zones, which is convenient during frequent flights. The stopwatch operates with an accuracy of 1/100th of a second, and the countdown timer supports settings up to 60 minutes. Five independent daily alarms help in planning tasks, and the automatic calendar does not require date correction until the year 2099. The watch case is hermetic and withstands water pressure up to 20 bar, making it suitable for professional swimming and diving.

Construction Materials and Ergonomics

The strap is made of a flexible polymer material that is not subject to corrosion from sweat or seawater and ensures a tight fit on the wrist. The spherical mineral glass has a curved shape, which increases its resistance to pressure and prevents glare. The control buttons have a ribbed surface for comfortable pressing even while wearing gloves. The steel back cover reliably protects the 5302 module from external influences.
