KUALA LUMPUR, 6 AUGUST 2026 —
Casio’s G-SHOCK unveiled the DW-H5600 Series on Monday, adding optical heart-rate and blood-oxygen sensors to the brand’s signature octagonal case.
Market Impact
The two new models, DW-H5600MB and DW-H5600EX, pair the retro octagon with bio-based resins, including the first carbon-fibre-reinforced resin used in a G-SHOCK. Black and blue IP metal bezels offer a premium finish while cutting weight, according to the company.
Activity tracking runs to running, walking, gym workouts and interval training, with real-time metrics displayed on the slimmed MIP LCD. Data syncs via Bluetooth to Polar’s algorithms for performance insights and training guidance.
Heart-rate accuracy is improved by pairing the watch with a smartphone so its GPS can correct the onboard accelerometer, Casio said. Blood-oxygen levels are also measured, but the company stressed the feature is for general wellness, not medical diagnosis.
USB charging covers training functions and notifications, while timekeeping remains solar-powered. Under typical use, one hour daily, a full three-hour charge delivers about seven days of runtime. Casio quotes roughly eight hours of indoor fluorescent lighting or two hours of direct sunlight per week as sufficient for solar top-ups.
