Blackview W40-Black Smartwatch, 1.43-inch AMOLED

Blackview W40-Black is a round Bluetooth smartwatch with a 1.43-inch AMOLED display, phone-call features, and fitness tracking. Its GPS is listed as smartphone-connected rather than built into the watch, so outdoor workout tracking depends on a compatible phone. The listing also claims an always-on display and up to seven days of use, but these are manufacturer claims, not independently verified results.

At a glance

Bluetooth calling and app notifications are presented as phone-linked features, not standalone cellular service.
The listing describes over 100 sports modes and GPS connection through a smartphone.
Health features include heart-rate, blood-oxygen, stress, and sleep tracking. The listing says results are for reference and the watch is not a medical device.
Two band styles are listed: silicone and nylon.

What to know before buying

Listing details to confirm

Listing details are inconsistent about water resistance: they call it waterproof, list IP68, and also state a depth of 10 meters. Confirm the applicable rating and usage limits before exposing it to water. The claimed seven-day use and approximately 25-day standby time are manufacturer estimates, and actual battery life may depend on use. The listed 128 MB storage and 481 KB RAM are separate figures, not interchangeable memory claims.

Aggregate ratings lean positive, with most ratings in the five- and four-star categories, but a notable share fall in the middle and lower categories. Without supplied review comments, specific customer-reported strengths or concerns cannot be identified. For buyers, the rating spread offers only a broad impression and does not establish call quality, tracking accuracy, battery life, or water performance.

Frequently asked questions

Does the W40-Black have built-in GPS?

The listing specifies GPS via smartphone. It does not substantiate standalone, built-in GPS.

Can it make and receive calls?

The listing claims Bluetooth phone-call features. This indicates phone-linked calling rather than cellular service from the watch.

What health measurements are listed?

Heart rate, blood oxygen, stress, and sleep tracking are described. The listing says the watch is not a medical device and that its results are for reference.

What bands are included?

The explicit contents list names one nylon strap and one silicone strap, along with a charging cable, product manual, and watch.

Is it suitable for swimming?

The listing's water-resistance details conflict, describing the watch as waterproof while also giving IP68 and a 10-meter depth. Confirm the intended water-use limits before swimming or submerging it.
