    • Very durable. Has enough compatibility with an iPhone 12 and 15 pro. 2 day battery life.
Color: Mystic Black
Review Image by Tadd Tadd
This has been a very good watch. The battery life can go 2 days on a full charge. It gives me the basic notifications and functionality that I want in a smart watch. This size and weight are less than my Fossil watches. Extremely good value for the price and it looks great! I don't like the look or the price of the apple watch and ice been an android user until the last 3 years or so. I It stays connected and some time ago the find my phone feature stopped working. This model I believe is the last model that works with the iPhone as the newer ones are not compatible. The band that came with it didn't last more than a few months but that's okay. The first replacement only lasted a few months, the 3rd one lasted about 7 months as you can see in the picture. I would definitely buy this watch again. ... show more

    • This thing's lasted me since 2022. Good Memories.
Color: Mystic Black
This was one of the best purchases I ever made. I bought this in October of 2022 and it 9/14/25 and it been perfect. I would like to say this thing is bulletproof but it's very close. It has a good battery life, easy to read, like the notification layout, has great GPS, and accurately tracks steps. It stopped receiving updates back in the end of 2023 so might get a new one soon but worth the purchase. Use every day since I got it. Good memories. And it save those memories. ... show more

    • Beautiful and Functional
Color: Mystic Silver
The watch is Renewed, so some cosmetic imperfections should be expected. There's a few scuffs on the bezel dial, but otherwise everything is great. One of the reasons I wanted this watch - was actually for that bezel dial. While as swiping is effective, there's a very nice tactile subtle click as you turn the outside bezel which is so satisfying. It did take forever to actually finish setting up with my phone - but I've had other samsung smart watches and so there's no need for instructions or booklets. It came in a box with the charger and the watch and I knew what to do. Everything is peachy. I wanted it to show my text messages, incoming calls, and another messaging app I use for work. It does. It does everything my even older samsung smart watch did - just a bit better. I'm not trying to get top of the line. I'm not trying to do anything crazy. My phone is not glued to me and thus I just needed something that looks like a watch on my wrist to buzz and remind me that someone does in fact need my attention. It does the job, it's pretty, it's functional. I'm a happy camper! ... show more

    • 1 Star Removed for watch band's spring bars/dead skin cells on case and in bevel recesses~
The only real issues I had with this watch was that the spring bars used for the watch band were the type that are flush (single shoulder), and the amount of residue on the refurbished case. Since the band was installed using a single shoulder spring bar and there are no holes to poke the spring in, you have to actually cut the bar (or bend it with pliers which could damage the lug indents or scratch the case). I wanted to remove the band for the reason that the watch itself had a small (but noticeable) amount of sweat/skin buildup near the lugs and around the bezel/ buttons from the previous owner. I wouldn't say that I'm a germaphobe, but it was a bit unsettling seeing this. The watch had a small nick on the bezel (which I was going to cover anyway for shock protection) and a couple of nearly imperceptible scratches around the watch band installation area (that will be covered by a watch band); these wouldn't be worth noting except I try to be as accurate in my reviews as possible. The battery life is on par with any post or article I've read regarding the Galaxy Watch 3. I get about a day and a half with always on display at brightness level 5 and Samsung Health running its little algorithms in the background and using the app "Facer". It arrived in a decent enough box, with a charger that seems to work fine. I go from low (10-20ish %) to 100 in about 2 hours. The band that came with the watch itself is nice enough to keep and use at a formal outing [provided you use a better spring bar (double shoulder/double flange e.g.)]. Screen was flawless. Shipping came a day early. Price is top notch. ... show more

This was my first time buying a refurbished electronic item from Amazon, so i was a little sketched out and combed the reviews before i bought. Some of the other reviews stated their watch came scratched, but mine did not. Back and front of the watch are perfect, like new. Others stated they didn't get any instructions included, but who cares, that's literally what the internet is for. And anyway set-up was easy, it connected to my Note 10+ almost immediately. A few reviews mentioned that the battery life was not great. This is one point i can agree on. I can say that I'm a teeny bit disappointed at how fast it drained, but I'll chalk that up to setting the watch up and spending time customizing the watch's features. At any rate, even if the battery endurance doesn't improve, I could easily spend the money to have the battery replaced, and this watch would still be MUCH cheaper than other options at the same quality. So i would say it's still a great value. Other than that, I'm pretty happy with the watch. Sleep tracking seems accurate, as do the other biometric tools, and that was a big reason i wanted a Galaxy Watch (Samsung removed them from the Note 10 series, and I've missed it since i got this phone!) Another reason I specifically wanted a Galaxy Watch was because of the store. There are literally thousands of customization options and various apps that you can download from the Galaxy Store, and that's something you won't get with no name knock-offs. To me that makes this watch capable of being a thousand times more productive than some generic watch. This alone makes it absolutely worth it, in my book. Overall, VERY pleased with my purchase and I'd do it again in a heartbeat. No name knock offs may be half the price, but if you spend the extra money and go ahead and get the refurbed Galaxy watch, you won't be disappointed! ... show more
