Casio Computer Co., Ltd. will release the 'GBX-H5600' on May 15 as a new product in the shock-resistant watch "G-SHOCK" brand. This model, from the "G-LIDE" series supporting extreme sports, is the first in the series to be equipped with a heart rate measurement function.
Since its launch in 1983, "G-SHOCK" has evolved in function, structure, and design based on its outstanding shock-resistant performance. The "G-LIDE" series has gained popularity as a model for extreme sports, equipped with functions useful for activities at the beach or waterside, such as a tide graph showing tidal conditions and moon data displaying the age and phases of the moon.
The 'GBX-H5600' we are announcing today is a shock-resistant watch equipped with a heart rate measurement function for the first time in the "G-LIDE" series, in addition to functions useful for beachside activities. We have created a model that meets a wide range of needs, from extreme sports like surfing to daily workouts.
By being equipped with an accelerometer in addition to an optical sensor capable of measuring heart rate, it not only visualizes conditions during exercise in real-time but can also measure distance and calories burned. Effective workouts can be performed through training functions supporting four activities: running, walking, gym workouts, and interval training. Various measured data are evaluated and analyzed using algorithms from Polar Electro, a company with a proven track record in the sports and health fields. Measurement information can be easily checked on the official smartphone app "CASIO WATCHES," supporting health management and performance improvement through detailed analysis.
The LCD utilizes a high-definition MIP LCD, making the display easy to read even under direct sunlight or from oblique angles, demonstrating high visibility outdoors.
In terms of design, translucent resin is used for the bezel, creating a see-through look where the internal structure can be seen through clear colors, realizing a refreshing appearance that looks great at the beach. Biomass plastics, which are expected to reduce environmental impact, are used for the main resin parts of the bezel, case, and band, achieving both design and environmental consideration.
Under our purpose of "Bringing the joy of surpassing today to everyone through the power of making surprises familiar," Casio has created unprecedented value in the watch business as well. Going forward, we will continue to provide the joy and surprise of wearing a watch, not only for the practicality of keeping time but also with diverse functions and highly individual designs.
