Great watch, maybe even best
Great watch, great battery life, fast processor(s), good connectivity, great addition to my Pixel phone and works flawlessly. I mostly use it for health and fitness tracking but having it be able to do many other things is really nice and it's just a nice watch when used just for the time. Looks great, feels great wearing it.

The perfect companion for my Pixel
After using the Google Pixel Watch 4 for a good while, I can say it’s been an excellent purchase. For me, it’s the best smartwatch if you have a Google phone specially if you use a Pixel 9a, like I do. The connection is smooth, notifications arrive instantly, and everything just feels natural in everyday use. One thing that really surprised me is the call audio quality voices sound clear and crisp, even when I’m outside. Battery life is also very solid; I don’t have to worry about charging it all the time, which is a big plus. You can also personalize it easily by changing watch faces and adjusting it to your style, which makes it feel unique. Overall, it’s a comfortable, and well-rounded smartwatch. I’d definitely recommend it if you’re looking for something that works great and looks good too

Upgraded to the Pixel Watch 4 from the 2!
Absolutely love the new watch!! Upgraded from the Pixel Watch 2 to this Pixel Watch 4! My 2 was the 41mm and I decided to go with the 45mm on the new one. At first I wasn't sure how to feel about it but after a couple days it's actually more comfortable then the 41mm was! The amount of things this watch can track and do is actually mind blowing! Also the battery life is much better then the 2 and lasts way longer! I love the new charging style for it too! Very useful information and pleased with the purchase!
