HK12 Ultra 4 AMOLED Smartwatch

HK12 Ultra 4 smartwatch with an AMOLED touchscreen, Bluetooth and everyday activity features, according to the supplier listing. GPS is described as smartphone-assisted. The seller describes NFC for use as a compatible access card, not for payments.

The supplier details conflict: the title claims 4G, but the technical sheet says there is no SIM slot. The app name, display dimensions and resolution, and battery capacity also vary across the listing. We cannot guarantee cellular connectivity or these specifications; confirm the variant and manual before purchase. The seller limits water exposure to occasional rain and splashes and says not to swim, bathe, or immerse the watch.

HK12 Ultra 4 is a model name, not an Apple product. Strap compatibility with other devices is unverified. Heart-rate, blood-pressure and wellness readings are simulated or indicative according to the supplier and are not a substitute for medical devices or advice.
