Waterproof specification: 20 ATM waterproof function
Mobile link function that can be linked with BluetoothⓇ communication with compatible smartphones
A mission log function that automatically records the altitude acquired by the watch and the route acquired by the smartphone's GPS in the app, and plots the altitude points on the trajectory.
The calorie consumption is calculated from the altitude + step count value, taking into account the elements of climbing, and is recorded as an activity log. From the G-SHOCK Master of G series "Gravity Master", which continues to evolve in pursuit of toughness, the mobility of a helicopter Introducing a model equipped with essential functions for flight missions and a carbon core guard structure.

A case made of carbon fiber reinforced resin with high strength and excellent weather resistance uses a strong carbon core guard structure to protect the module, and in addition to the shock-resistant structure that is G-SHOCK's core technology, the vibration-resistant structure has also been strengthened.

A three-layer structure with a carbon fiber sheet inserted is used for the resin that forms the bezel.

By making the top layer a skeleton resin, the bezel is finished with a carbon texture and improved wear resistance.

The design motif is a helicopter control stick, and three buttons are placed at the 3 o'clock side.

It also has practicality that pursues operability by blind touch.

The dial is colored with the iconic orange and blue colors used in the uniforms of the Air Rescue Team.

In addition to the standard black color, the band has a lineup of blue and orange finished with bold color blocks.

The face design is accented with orange everywhere to express the strength and spirit of the Air Rescue Team.

In terms of functionality, it is equipped with a quad sensor that includes a small sensor that can measure direction, altitude/barometric pressure, and temperature, as well as an acceleration sensor that can measure steps.

Easily understand changes in the natural environment and activity history to support flight missions.

Additionally, in addition to time correction through collaboration with the G-SHOCK dedicated app, it is also equipped with a "mission log function".

Automatically records the altitude acquired by the watch and the route acquired by the smartphone's GPS in the app.

Plot manually acquired altitude points on the trajectory

Furthermore, based on the altitude and number of steps measured, the calorie consumption is calculated taking into account the climbing factor and recorded as an activity log.

With the "Location Indicator Function", if you record your current location on the app by pressing a button on the watch, you can also display the direction to the recorded point on the second hand and the distance on the LCD.

In addition, with the "mode switching/customization function", you can set the mode ON/OFF and display switching on the app, and customize it by using only the necessary functions or changing the display order according to the purpose.

Introducing the "Gravity Master" GR-B200, which has an evolved toughness structure designed for use in harsh environments, and supports quick decisions and accurate actions during flight missions through sensor functions and collaboration with smartphones.

*The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude.

If the atmospheric pressure changes due to weather conditions, the altitude of the measured value will also change.
