– Supports Range of Training Activities from Running to Gym Workouts –

MALAYSIA, KUALA LUMPUR, 19th May 2023 – Casio Malaysia has released the new addition to the sports-driven G-SQUAD line in the G-SHOCK family of shock-resistant watches today. The five new DW-H5600 watches inherit the iconic shape of the very first G-SHOCK and are equipped with an optical sensor to measure heart rate.

Developed in the quest to construct a watch that wouldn’t break, even if dropped, the first G-SHOCK debuted in 1983. Casio has continued ever since to advance G-SHOCK functions, construction, and design, with a constant focus on the shock-resistance of these watches. The iconic form of the very first model, the DW-5000C, has been passed down to subsequent generations of G-SHOCK timepieces, and the 5600 line, which inherits that form, has continually evolved, incorporating the most advanced functions available in each new era.

The new DW-H5600 timepieces retain the form of the first-ever G-SHOCK while delivering more advanced functions, all in a shock-resistant watch equipped with a heart rate monitor useful for sports activities. The new watches support four different activities or exercises — running, walking, gym workouts, and interval training — and they are equipped with an optical sensor and an accelerometer to measure heart rate, distance, and calories burned. They utilize algorithms from Polar Electro Oy, a pioneer in the industry that has spent nearly 50 years perfecting the art of personalized guidance in fitness, sport, and health, to provide analysis on training and sleep based on tracked data.

  • Sensors for Activity Tracking

The case back is equipped with an optical sensor that measures heart rate by emitting LED light to track changes in blood flow. The watch also includes an accelerometer to count steps. For even greater accuracy of distance measurement, the watch can be paired with smartphone GPS to fine-tune the data captured by the accelerometer.

  • Four Activity Modes

The watch supports running, walking, gym workouts, and interval training. An activity can be selected with the touch of a button to track and display a variety of measurements in real-time, including distance, speed, and calories burned.

  • Training Analysis and Sleep Tracking Using Polar Electro Oy Algorithms

The watch measures the burden on the heart and lungs according to training time and intensity, analyzes ratios of energy used separately for carbohydrates, proteins, and fats, and performs sleep tracking. This data analysis utilizes algorithms from Polar Electro Oy, a company with a well-established reputation for heart rate-focused training analysis.
