Thin enough to forget, bright enough to trust
At 9 millimetres thick, SBW-103 slides under a shirt cuff and disappears on the wrist — no lump, no snag. The alloy case pairs with a 316 stainless-steel bottom shell whose in-mould steel plate keeps the ECG and optical sensors pressed close to the skin for clean readings.
The 500 Hz Goodix 3228T ECG channel records medical-style heart readings with heart-health analysis in seconds, backed by 24-hour heart rate, blood oxygen, blood-pressure trends and sleep staging. The micro-physical-examination mode extends screening to blood lipids, uric acid and non-invasive blood-sugar trends.
Then there is the party trick: a genuinely useful high-intensity flashlight, built into the case, for finding the keyhole or lighting the stairs. Bluetooth calling, NFC access control and offline Alipay payment handle the rest of the day.
Six finishes across silicone, leather and steel straps keep it versatile, and every surface — strap, crown, app splash, colour box — is open for OEM customisation.
