Compact 28 mm smartwatch for daily health tracking

The allentian ET381 fits wrists that prefer a smaller 28 mm round dial and an aluminum alloy case. It pairs with Android and iOS devices to deliver call, message and app alerts directly to the AMOLED touchscreen. A silicone sports strap and magnetic charging complete the package for everyday wear.

Up to 21 days runtime with magnetic charging

A single charge lasts between 15 and 21 days, reducing the need for frequent top-ups. Life-waterproof sealing handles sweat, rain and hand-washing without extra bulk. The magnetic data line snaps on quickly, keeping the 195 g unit ready for continuous heart-rate, blood-oxygen and temperature monitoring.

Health suite includes ECG.

Beyond standard step counting and sleep analysis, the watch offers on-demand ECG, blood-pressure, blood-oxygen, body-temperature, uric-acid and blood-lipid readings. Buyers who need clinical-grade accuracy or a dedicated medical device should look elsewhere.

Questions about this item

How do I charge the ET381 smart watch and what step do people often miss?

Align the magnetic charger with the contacts on the back of the 28 mm case until it clicks; the step users miss is cleaning both surfaces first so the connection holds through a full 15-21 day cycle.

Which part of the ET381 will need replacement first with daily wear?

The silicone sports strap stretches and discolours before the aluminum alloy case or AMOLED screen, so plan to swap the band after several months of sweat and UV exposure.

What limits the ET381 during a long workout with GPS and heart-rate tracking active?

Continuous Bluetooth calling, heart-rate monitoring and the AMOLED display draw the 195 g unit down well before the 15-21 day standby rating, so expect a recharge mid-day.
