Men's watch Casio G-Shock GDF-100-1AER with barometer, altimeter, and thermometer

Men's Casio G-Shock GDF-100-1AER Watch with Barometer, Altimeter, and Thermometer

A professional wrist device designed for use in extreme field, sports, and tactical conditions where data accuracy and overall structural durability are crucial. The signature polymer plastic case with a special complex geometry provides shock absorption during falls from heights and mechanical collisions. The black matte finish of the construction details makes the accessory inconspicuous on the wrist, preventing unwanted glare in the sun. The image image_2eecfd.jpg shows the complete set of the original device, including a dense cardboard sleeve, a branded closed box, a printed user manual for module 3255, and the electronic device itself. The model is in stable demand among military personnel, tourists, climbers, and rescuers due to its autonomy and complete independence from cellular networks or GPS signals.

Measurement Potential of the Twin Sensor

A miniature high-sensitivity twin sensor is integrated into the left protruding part of the case, continuously monitoring environmental parameters. The obtained data is displayed on a monochrome liquid crystal display in real-time, allowing for quick reactions to weather changes during transitions.

Specialized built-in sensors provide the following measurement functions:

• The altimeter determines the current altitude above sea level based on atmospheric pressure readings.

• The barometer records the current air pressure and displays the change dynamics on a circular graphic indicator with a red scale.

• The thermometer measures the ambient air temperature over a wide operating range with a step of one-tenth of a degree.

A special sensor block isolation system prevents the penetration of dirt particles, fine dust, and moisture into the measurement chambers during sudden pressure changes.

Design Parameters of Autonomy and Ergonomics

The device's electronic board is optimized for minimal energy consumption, ensuring uninterrupted operation from a single lithium power cell for several years. For convenience in complete darkness, a powerful Super Illuminator LED backlight with afterglow time adjustment is provided.

The physical elements of the case and strap provide the following operational advantages for prolonged wear:

• An elastic polymer strap with a double metal buckle ensures a secure fit on any wrist circumference.

• Reinforced mineral glass is recessed into the protective bezel, virtually eliminating scratches when in contact with rocks or equipment.

• Large textured buttons with anti-slip notches allow easy control of the device's functions without removing thick tactical gloves.

The high level of water resistance of the case allows the device to be used without fear during heavy rain, swimming, and short-term water immersion.
