Allentian Tk12 smart watch

The Allentian Tk12 is a compact smart watch with a 28 mm aluminium-alloy case and a TFT touch screen. It weighs 150 g and uses a TPU strap with a classic buckle. The device pairs with Android and iOS phones to deliver Bluetooth calling, message alerts and voice-assistant access. It is designed for adults and teenagers who want a lightweight daily companion.

Build and daily wear

The square aluminium case and magnetic charging cable give a tidy desk setup, while the TPU strap resists sweat during workouts. Life-waterproof rating handles rain and hand-washing but not swimming. Touch and button controls let you answer calls, trigger a remote selfie or check notifications without reaching for the phone. Battery life stays under seven days per charge.

Health upgrade path

The watch adds non-invasive blood-glucose estimation, ECG, PPG heart-rate tracking, blood-oxygen and blood-pressure readings to basic step and sleep data. SOS alerts can notify contacts in an emergency. Buyers who need clinical-grade diagnostics or multi-day expeditions without charging should look elsewhere. The feature set suits users moving up from a simple step counter to broader wellness insight.
