I bought a mid range (~$200) smart watch pretty recently. It's the amazfit t-rex 2. I didn't want to pay what Samsung and Google were charging, but I wanted more than basic. The battery lasts like a week, it's water resistant (I wore it in a pool and it was fine), it buzzes for calls and texts, and it tracks sleep and activity. The app is meh but works fine. The watch itself isn't always intuitive to navigate since what you're looking for could be in any of like five separate locations, but you'll only find it in one of them.

Anyway, I love it. For the price, it's surprisingly close to what premium shit is doing, and premium shit is double the price. I get annoyed at times, but everything is annoying at times. It might be out of your price range, but if you're on the fence, I've banged it up a few times at work and it's still like new. However, I have a coworker who was impressed by it when I showed it to him, so he bought one and it died on him after like 2 months. So maybe I got lucky, maybe he got unlucky. Keep it in mind and hold onto your receipt so you can do a return if my recommendation goes south.
