Everyday smartwatch for health tracking

The allentian ET280 is a lightweight wearable designed for daily wellness monitoring. It suits users who want continuous heart-rate, blood-oxygen, blood-pressure and temperature readings on the wrist. Bluetooth calling and smart notifications keep the phone in a pocket. The square AMOLED face and silicone strap fit a sporty, neutral style.

15 to 21 day battery with magnetic charging

A single charge lasts between 15 and 21 days depending on call and sensor usage. Heavy Bluetooth calling or constant sensor polling will shorten the window toward the lower figure. The magnetic cable snaps on without fiddly pins. There is no fast-charge spec quoted, so plan an overnight top-up when the battery runs low.

Square 28 mm aluminium case fits slim wrists

The case measures 28 mm across and weighs 195 g, making it compact enough for smaller wrists. It pairs with Android and iOS via Bluetooth for calls, remote shutter and alerts. Life-waterproof rating handles sweat and rain but not swimming. The package includes the watch, magnetic cable, manual and box — no extra straps or charging brick.

Questions about this item

Will the 28 mm case and 195 g weight feel balanced on a narrow wrist alongside a traditional metal watch?

The square aluminum-alloy case measures 28 mm and the complete watch weighs 195 g, so it sits close to the wrist without the bulk of larger smart watches.

How can I verify the AMOLED touchscreen and magnetic charger are functioning correctly after the first charge?

The AMOLED display lights up instantly on wrist raise, touch and button inputs respond without lag, and the magnetic cable snaps into place with a visible charging animation on screen.

Which items arrive in the box and what must I supply myself?

The package contains the ET280 watch, a silicone sport strap, a magnetic data cable, a printed manual and the retail box; a USB power adapter for the cable is not included.
