The AOYBWK smartwatch pairs a listed 1.85-inch screen with Bluetooth calling and fitness tracking. Its feature claims include heart-rate, blood-pressure and sleep monitoring, but the supplied specifications do not confirm all of these functions or the headline IP68 rating.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the technical specifications give a 400 Milliamp Hours battery and a 15 days battery-life claim, while feature text instead claims a 250 mAh battery, 7 days of normal use and 30 days standby. The listing also names AOYBWK in the product details but calls the watch AcclaFit in feature copy, and its Wear OS 3.0 claim is not reconciled with the described smartphone-app pairing. IP68 and swimming or diving use appear in promotional text, while the technical field only says Waterproof. Check the selected listing for the exact model and supported use before relying on these claims.

Aggregate ratings are entirely five-star across the supplied rating distribution, but there is no customer-comment summary to show what owners liked or how the watch performs. The rating alone cannot confirm the calling, health-tracking, battery or water-resistance claims, so buyers should weigh those listing inconsistencies against their needs.

Frequently asked questions

Can this watch make and answer calls?

The feature text claims Bluetooth calling using a built-in microphone and speaker, with a smartphone connection. Confirm compatibility with your phone before buying.

How long does the battery last?

The technical details list 15 days and a 400 Milliamp Hours battery. Feature text instead claims 7 days of normal use, 30 days standby and a 250 mAh battery, so runtime is unclear.

Is it suitable for swimming?

The feature text claims IP68 and mentions swimming, but the technical specification only says Waterproof. The listing also warns against hot water, including hot showers. Check the selected model's water-use guidance.

Are the health measurements medical-grade?

No such status is established in the supplied listing. Treat the heart-rate, blood-pressure and blood-oxygen features as consumer tracking claims, not medical measurements.
