Health data without another screen
E900 starts from a simple observation: the wrist is the right place to read the body, but the wrong place for one more glowing display. So SBW-101 drops the screen entirely. A quiet vibration and a small LED are all you feel and see — every waveform, trend and report lives in the G band app, where there is room to actually understand it.
The heart of the band is a Goodix 3228T electrocardiograph sampling at 500 Hz. Rest a finger on the stainless-steel contact and it records a medical-style ECG with HRV analysis in seconds — the kind of reading that used to require a chest strap. Around it, a PD2325 optical front end tracks heart rate, blood oxygen and skin temperature around the clock.
Beyond the vitals, the band screens blood composition — lipids, uric acid and a non-invasive blood-sugar assessment — and reads body composition through the same sensor array. Nothing here replaces a lab test, but as a daily early-warning companion it gives wearers and their families something concrete to act on.
A 180 mAh cell sips power for 7 to 15 days per charge, and IP68 sealing means rain, showers and swim laps are all fine. Six strap options — three braided, three silicone — let it disappear into office, gym or sleep. For brands, every surface from strap colour to app splash screen is open for customisation.
