Apple, Google, and Samsung are all running deals this Prime day on their smartwatches. Unlike some sales events, we're seeing good prices today on the current, newest models from each brand. Apple's watches are all at the lowest prices I've ever seen for the Series 11, SE 3, and Ultra 3. Below are the best deals I've found, along with deals for accessories like wireless charging stations.

If you're trying to decide between the Pixel and Samsung watches, check out my reviews: the Pixel Watch 4 has ultra-fast charging and a convenient dock. The Samsung Galaxy Watch has thoughtful design in its health and fitness apps. I prefer the Samsung from a fitness point of view, but they're both good watches and there's a strong argument for getting one that matches your phone. Each brand has a few extra features that you can unlock when you use a Samsung Galaxy watch with a Samsung Galaxy phone, or a Pixel watch with a Pixel phone.

Apple's current models of watch are on sale for up to $100 off:

• The Apple Watch Series 11 starts at $279, originally $399.

• The Apple Watch SE 3 starts at $199, originally $249.

• This Apple Watch Ultra 3 is now $649.99, originally $649.

Some accessories worth looking at:

• This keychain charger for $12.14 (down from $15.99) can store enough juice to charge an Apple Watch 2-3 times (or two times for an Ultra).

• This charging station for $15.30 (down from $25.99) can charge your Apple Watch, iPhone, and AirPods.
