First smart watch, I like it
This watch is pretty great. I bought it was a renewed watch since I wasn't sure how much I'd like having a smart watch, but I'm pretty happy with it. It's my first smart watch; I bought it originally to keep track of my steps/general fitness and for the obvious time function itself. For the most part, I haven't had issues with it. I've dropped it a couple of times, I've dropped something onto it and smacked it into something when swinging my arm around, but there's no obvious damage to it at all, it still functions as intended. The wristband is also holding up surprisingly well, given that I've had it for over a year from when I originally bought the watch (ordered it 5 Feb 24). My ONLY real grievance about this watch is, because I wear it on my left wrist, when I bend my hand back enough it'll trigger the buttons. During exercise, this'll pause my workout tracker; outside of exercise, it can trigger one of the trackers to start tracking something I'm not actually doing. Both are annoying, but they're minor inconveniences. Otherwise, it does what I want it to: tracks my steps, fits correctly, tracks my workouts, tells me the time. The "AI" function on it, Bixli, is kind of useless? I don't know. You have to yell at her to make her listen, and even that's a struggle. I've tried her out a couple of times and it didn't go well, so I just disabled the function. The other features are good though, and there's apps you can download if you want to really personalize your watch face. Otherwise, Samsung does have a lot of good ones to choose from in the watch itself. Oh, I've also taken this watch swimming and into the shower and it did just fine. The water might trigger a sensor to where it thinks you're trying to do something on the watch if it hits it just right, but otherwise no issues. It also has a water "remover" function that you can scroll to and it'll vibrate to shake the water out. The battery life is pretty good. I usually charge it every night or every other night, especially if I know I'm going to the gym, but general use it goes around 2-3 full days before it needs another charge. Obviously, the more you use it, the sooner it'll need to be recharged. You can just slap it onto the charger base and you're good, it doesn't take long to recharge at all. For example: right now, my watch is on standard power mode and says 88% battery left. It estimates it has 2 days, 5 hours, and 21 minutes of battery life left. It was fully charged this morning, before I put it on and went to the gym. The text function is also good, you can read texts pretty quickly and it has quick responses for you to send, or you can write something out on your watch face, but that obviously is a little more time consuming. Phone calls also go through and you can answer them on your watch, so that can be a handy function as well, but I rarely use it. It obviously has other functions/apps you can add to it, but I'm just telling you what I use and what works for me. Overall, I'm happy with this watch. I recommend it if you just want something simple for time and tracking things.

Very durable. Has enough compatibility with an iPhone 12 and 15 pro. 2 day battery life.
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.

Great watch, iffy refurbishing
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.

Works as it should.
This was purchased as a gift for my boyfriend. His original.wat h finally died after living the blue collar life. I purchased this one as a replacement. He says it works well, no issues with the device itself. The only real issue he had was that standard universal watch bands weren't wide enough for it where the connect to the unit itself. Not a device problem but just something to be aware of. Definitely measure the device and compare sizes before purchase. Overall its been great for him. *I did purchase a refurbished unit.

Feature rich fitness/smart watch
There are already many reviews for this generation of Samsung fitness/smart watch so I'll just hit the highlights of why I like it. First, I find the S3 to be a feature rich and stylish watch. I very much like being able to access the watch's features using the bezel wheel. No tapping the screen or swiping to see information if I don't choose to. I have a Samsung phone so the watch and App were easy for me to set up and understand. The watch's screen is bright, sharp, colorful, and there are many modifiable watch faces available. I don't keep the GPS feature turned on so my battery life is a good 2 days. I have tried a couple of other fitness watches over the years, some with much longer battery life, but I have mostly used a version of Fitbit watch since 2015. Because I wanted to try something new and after watching/reading a number of reviews for this watch, I purchased a renewed one for around $100. I have been having fun with the watch and have nothing bad to say about it except step counts and some fitness info does not match up with my Fitbit watch results. I guess I will have to calculate a fudge factor in my head for the difference. Anyway, I liked the watch enough to buy a renewed S4 {next gen} watch that offers a few more features over the S3 such as an important new OS. Luckily, the Samsung App allows me to enable 2 watches so I can keep 1 watch charged all the time and switch back and forth between them. Samsung has promised 4 years of software updates so I will have plenty of time with these watches to try out the Samsung ecosystem before I have to decide to move on {or not} to their next gen watch. I believe S3 support updates end the Fall of 2023. The last thing I will say is that the $399 Samsung wanted for these premium watches brand new is way out of my cost to value price range so I was happy to be able to purchase them renewed. The good news is that their 5th gen fitness watch is more reasonably priced. But if you want to kick the tires on a premium Samsung fitness/smart watch without it costing an arm and a leg, I'd recommend you buy it renewed {excellent condition} to see if it just might become your new favorite watch.

Does exactly what it's meant for!
Hello, long review alert. 1. I use this watch all day to track my step count and physical activities, to receive phone calls and notifications without having to pull out my phone at work, and to track my sleep at night. So far, this has proven to be an amazing investment. 2. Battery life was very low the first few days(half a day or less) but I realized that I was maybe letting too many notifications go through. Once I reduced the amount of notifications (sms,calls,some other apps), it now lasts a day and a half. I don't use the always on screen also btw. 3. I don't like to tighten the bracelet too much because it's kind of a leather type bracelet and looks like it could wear after a while. The watch stills does the readings very well even so. I bought a replacement bracelet so I could preserve this one for other occasions. 4. Speaker and mic are awesome, people hear me very well and without distortion and I hear them clearly also. Bluetooth also works very well. I did not try adding a eSIM yet but once I do I will update the review. 5. It came without scratches or apparent signs of tear and wear. My kids dropped it at least twice and it did not scratch. 6. It glitched once(quick panel wouldn't show) but after reading somewhere that I should just restart the watch, it works just fine now. In conclusion, I would recommend this watch for people who won't need it for heavy usage. Would make an awesome gift for people who work a lot and need a good track of when to take a little break and stretch. Very easy to use and with a variety of beautiful watch faces to download.

Still strong in 2025?
UPDATED: Still works with iPhone but Samsung dropped support for them in October 2025. You can no longer add watch faces or apps to the watch, end of life, no longer recommend. Original Review: Bought reconditioned in 2023 to use with iPhone, as newer versions are not compatible. Unit i received is flawless and allows me to receive notifications from all of my iPhone apps such as MS teams, outlook, SMS, FB messenger, Spotify, etc automatically. I can answer and reject calls and use built in mic/speaker. Has a SM for cell service but u donโt use that feature. Vibrate alerts/alarms, customizable faces. Voice recognition with Bigby app. No complaints, for a $90 smart watch way better than the other cheap options. Attractive, durable, highly functional. I use a black steel band for dress and Velcro band for play. UPDATE 6 months later: very happy with my purchase. Battery life has been good, no problems other than occasionally an app can somehow run battery out if not on low power mode. If i charge each night, not an issue. When i use low power mode has battery for days. No regrets for my uses., amazing value for the hard earned $$$.
