Description

Monitor your health, track your fitness, and match your style with the Galaxy Watch3 GPS Smartwatch from Samsung. This smartwatch features a rotating bezel that makes it easy and intuitive to navigate through available apps and manage your music on the full-color 1.4" display. Some apps let you keep track of your health as you work out and throughout the day. You can use them to monitor your heart rate (ECG), blood pressure, and VO2 Max (blood oxygen) with a SpO2 sensor. Other apps can track your workouts and deliver detailed results of exercises, activities, and sports. Meeting your fitness goals requires that you get a good night's rest and the Watch3 can help with that too. Wear it throughout the night and use the sleep tracker to generate an overall Sleep Score. Based on this score, the Watch3 will give you recommendations on how to achieve better rest in the future. When you're full of energy and ready to exercise, the Galaxy Watch3 can play your favorite music to get you motivated without the need for a mobile phone. Just load up your favorite tracks on its 8GB of built-in storage and pair your favorite Bluetooth headphones.

    • First smart watch, I like it
Color: Mystic Black
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. ... show more

    • Best watch for so many functions.
Color: Mystic Black
Great watch. I needed something for my husband that would be easy for him to use and navigate through the functions and this watch is perfect. It tracks steps, heart rates, has calendar, messaging and answering capabilities plus its waterproof and durable. The multitude of functions are easily accessed too. Just overall its great and comfortabletowear since its not bulky either! ... 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

    • 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
