# 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.

## Cons

## Before you buy

- 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.

- Anyone relying on smartwatch health readings for medical decisions.
- Buyers who need clearly established water-use limits before purchase.

## Customer feedback

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.
