Over a year ago now I ordered a galaxy watch 3 from Amazon. It was "renewed", so Amazon's version of refurbished. I had pretty low expectations for it due to its age, but I've been pleasantly surprised.

Tizen os was already at its end of life, but surprisingly I've gotten a few software updates over my year with it.

It can do pretty much everything I need it to. Sleep tracking works well enough, I can take calls/send texts and interact with media playing on my phone. Heart rate monitoring seems to be pretty accurate when testing against the one at the doctor. I can install games to play on it for when I'm extremely bored lol. Watch faces are a bit limited due to tizen os being basically abandoned, but digital dashboard is so good that I don't need anything else.

Battery life is around 2 days with always on turned off, one day with it on. The main thing I was concerned about was the water proofing of it. It's refurbished, and that typically means the seals have been tampered with and it's not quite as water proof as it should be.

I work as a car detailer, and for the past full year this watch has been submerged in a wash bucket many times per day, sprayed with extremely harsh chemicals, pressure washed at point blank range and never once has it caused issues.

This thing was $35. Over a year ago now. Best $35 I've ever spent
