Allentian Hk87 AMOLED Smart Watch

The Allentian Hk87 is a compact wearable designed for men who want health tracking and Bluetooth calling on a 29 to 35 mm round AMOLED dial. It pairs with Android and iOS devices and weighs 150 g with a silicone sports strap. The magnetic charger reaches full power in 15 to 21 days of typical use.

Thermals Noise and Power Draw

The aluminium alloy case stays cool against the skin during continuous heart rate, blood pressure and blood oxygen monitoring. No moving parts mean silent operation in any environment. The magnetic charging system keeps the sealed life-waterproof rating intact while topping up the battery over the 15 to 21 day cycle.

Build Fit and Freedoms

The 29 to 35 mm case slips under shirt cuffs and fits narrow wrists without extra bulk. Bluetooth calling and remote camera control free the phone from your hand during workouts or commutes. Life-waterproof sealing handles sweat and rain but is not rated for swimming or diving. Buyers who need built-in GPS, onboard music storage or swim-grade water resistance should look elsewhere.

Questions about this item

How do I charge the Hk87 watch and what mistake should I avoid?

Align the magnetic charger pins with the contacts on the case back; forcing the cable the wrong way can bend the pins and stop charging.

Which parts of the Hk87 will need replacement over time?

The silicone sports strap will wear first; the magnetic charging cable can also fray, while the aluminum alloy case and AMOLED screen are not user-serviceable.

What limit appears first during continuous use of the Hk87?

The battery typically lasts 15 to 21 days per charge, so runtime is the first constraint under sustained heart-rate, blood-oxygen and Bluetooth-call monitoring.
