Waterproof specification: 20 ATM waterproof function Mobile link function that can be linked with Bluetooth - R 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 al..
