An evolved version of the "G-LIDE" that features a heart rate monitoring function for the first time.
Since its launch in 1983, the "G-SHOCK" has evolved its functions, structure, and design based on its superior shock resistance. The "G-LIDE" is a popular model for extreme sports, equipped with functions useful for beach and waterside activities such as surfing, including a tide graph that shows the tides and moon data that displays the lunar phase and stage of the moon.
The newly announced GBX-H5600 is a shock-resistant watch that, in addition to features useful for beach activities, is the first in the G-LIDE series to incorporate a heart rate monitoring function. It is designed to meet a wide range of needs, from extreme sports such as surfing to daily workouts.

The various measured data are evaluated and analyzed using algorithms from Polar Electro, a company with a strong reputation in the sports and health fields. Measurement information can be easily viewed using the official smartphone app "CASIO WATCHES," and detailed analysis supports health management and performance improvement.

In terms of design, the use of translucent resin for the bezel creates a see-through effect that allows the internal structure to be seen through the clear color, resulting in a refreshing look that stands out on the beach. The main resin parts of the bezel, case, and band are made of biomass plastic, which is expected to reduce the environmental impact, thus demonstrating consideration for the environment.
Under its purpose of "bringing the joy of everyday life closer to everyone, and creating a joy that surpasses today's experiences," the company has created unprecedented value in its watch business. Moving forward, it intends to continue providing the joy and surprise of wearing watches not only through the practical function of telling time, but also through a variety of functions and uniquely designed pieces.
