This time, we adopted a reflector that reflects light even in the dark (GBA-800LU-1A1JF only phosphorescent material), and finished it with a design that can further enjoy fashion and activities in the night scene.
In terms of functions, it cooperates with the dedicated application “G-SHOC KConnected” to assist individual activities with functions suitable for workouts.
Step count measurement function with 3-axis acceleration sensor, multi-timer of up to 5 x 20 sets, lap memory up to 200, etc., useful for daily health management and improving physical fitness
In addition, it is easy to create a training menu and record activities such as step log with 5-step exercise intensity, calorie calculation and target step setting, timer menu creation + transfer, stopwatch measurement data storage, data batch confirmation, etc. Enjoy
In pursuit of the original value of the watch, such as automatic time correction by linking apps, it also has utility such as an auto LED light that is useful for workouts in dark places.
In order to improve wearability, the back of the band has a back wing and prevention of misalignment due to the ring, and a large number of band holes are provided for fine fitting adjustment.
This allows for subtle adjustments in size.

Brand introduction G-SHOCK has built a new concept of toughness on watches
It all started with a developer's passion for creating a watch that would not break even if dropped, and a reckless challenge that overturned the common sense of the time.
Over 200 prototypes have been repeated, and about two years have been spent, and the shock-resistant structure has been completed.
It is the birth of technology to play the core of toughness
Since then, G-SHOCK has continued to evolve endlessly
Structure, material, function
Pursuing further toughness in every aspect
