  • Very durable. Has enough compatibility with an iPhone 12 and 15 pro. 2 day battery life.
Color: Mystic Black
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

  • 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

  • Great watch, iffy refurbishing
Color: Mystic Black
Watch itself is great, looks very nice, screen is great, functionality is good, especially for workout tracking. I use mine mostly for phone notifications, workout, health, and sleep tracking, checking the weather, and controlling music. Does all these very well and looks good doing it. Battery life is over 2 days, even when I've tracked workouts both days, which is a big step above my Galaxy Watch 1, which I would have to charge almost daily. And for the price (about 100$ right now compared to 300$+ for the newest generation) it's way worth it. I was a little worried about the size, but the 45mm Galaxy Watch 3 is just a bit bigger than the 41mm Galaxy Watch 1, so they were definitely more efficient with space this time around, fitting a much bigger screen on a slightly bigger watch. Unless you have very very thin arms, you'll probably be happy with the size. The only bad thing is that mine came with two noticeable scratches on the glass face, and a couple on the bezel. I thought about returning it but didn't want to go through the hassle, since the glass scratch (the one I cared about most) wasn't really taking away from my experience. It's mostly noticeable when the screen is off, but when the screen is on it becomes a lot harder to see. Also I'm not a huge fan of the leather band it came with, but it does the job well enough, and you can find plenty of replacements on amazon. ... show more

  • Excellent Condition. Loving it.
Color: Mystic Black
Writing this review after 4 months of usage.Arrived as advertised i.e. Refurbished but in excellent condition. No scratches were found. Battery lasts for good 2 days with average use. Came with new leather strap and screen protector. Works perfectly. Love the dial selector on the watch. Using it with Iphone 15 pro max, slight delay in notifications but i get notified of incoming messages/calls. Justifies the price. App on Iphone helps keep track of the daily health targets. ... show more

  • Overall, Quite Pleased.
Color: Bronze
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
