GREAT WATCH BUT NOW THE BAND FALLS OFF ALL DAY EVERY DAY
Rating: 5
I've had this watch for over a year now I believe, and now the band falls off all the time. the band isn't ripped or anything, just the little pin that pushes in to both sides of the watch face won't stay on.I am not happy about not being able to wear it. Can someone please help me?

Beautiful!
Rating: 5
I love this watch. I've been through a few smartwatches and always returned to the gear fit due to the size and shape. I then upgraded to the s2 for the functionality. This watch is the perfect mix of the two. The notifications, the agenda and the health features and exactly what I need. The classic feels much lighter than the s2 and the ridges on the bezel make it easier for me to use. But what I love is the look, it is gorgeous!

love this new piece of Tech
Rating: 5
I was very skeptical at first about getting a smart watch saying i would hardly use it. So recently i won a Gear s2 and been using it fr a few days. WOW what a gadget, HOW DID I SURVIVE WITHOUT this assistant on my hand giving me all my notifications on my wrist. Thanks a Million SAMSUNG. Now just waiting for my Free tablet to get here lol.

Samsung classic smart watch
Rating: 5
Hello Everyone, I have written before about things. I am not tech savvy and I don't really don't use my Samsung galaxy 6 edge the way that I am supposed to, but I love the combination of both my watch and phone together. I can't hear my phone all the time and missed 2 emergency calls. I bought the smart watch so that I don't miss anything. I can tell you it goes off with all notifications that are on my phone. I can program everything and anything and my watch lets me know. I realize that it sounds lazy but I have been able to program things for my job also. It vibrates and is non-intrusive. Not like the notification from the phone. Also, I can not carry my phone on my person at work... THIS IS AWESOME !!!!! My only thing against the watch is that there seems to be no thought process to women. The watch bands are either black or brown. I actually ordered one on the market that I changed it to. I would have like to have the Samsung brand to complete the watch and be able to change it easily. I hope that they consider this for their accessories soon.

This is truly a smart watch!
Rating: 5
Without looking garish and futuristic, this Gear S2 Classic truly is a smart watch. From turning it on for the first time, it links seamlessly with my Galaxy Note5 and complements it perfectly. The display is bright and clear, the apps from mail to uber are a joy to use. And all at the same time it looks like a proper watch. As an added bonus, it is water resistant. The battery life is excellent. So far I have managed 3 days without having to recharge the battery, and that's without setting it to greyscale mode.

I put my Swiss Timepieces on the shelf
Rating: 5
I would consider myself a watch enthusiast and collector with many Swiss Made high end timepieces. I have been waiting a long time for a smart watch that I could wear alone on my wrist instead of a watch on my left and a fitness band on my right. The Samsung Gear S2 Classic gives me both in a beautiful package and thousands less than any other watch in my collection. Well Done Samsung!!!!!

Almost Very Happy
Rating: 4
I am really pleased with the Gear S2 Classic. First and foremost, I wanted a good watch. I have already changed the band to one more of my liking. I usually have my phone with me anyway, and have basically been using in standalone mode, and get 3-4 days of battery before the next charging. It's snappy and responsive. There are a minimum set of apps that I have installed and use. I don't see me using a browser or even a map on my wrist since I have my phone. However, I would like to see in a future update...give the option for the watch to wake up to the last app open and in use!!! In other words, I use my stopwatch and timer quite often...it's a pain for the watch to come on, and the clock face is there and then I have to dig to open the app in use. I'd like to be able to open up and see some apps like timer or stopwatch greet me when the watch wakes up. This was a feature available in the Galaxy Gear S (original). Better way to access recent apps, like 2 finger option on Gear S1. Maybe ability to swap top and bottom physical buttons for functionality. Also, what's the deal with S-Health? Is there no way to sync up with my phone? A standalone compass would be nice, if possible with hardware. Otherwise, happy with my purchase.

Great Watch
Rating: 4
The watch is great. The only down fall to me is the price. I feel that the tech. Side of it will improve in time so the price that you pay for it now might not be worth it since you are spending more than what you pay for a cell phone upfront. For the price you do wish it could do more. But it does have a lot of positives as far as uploading and controlling music and pictures. Tracks your health. The faces are the best, there's something out there for everyone. And the faces itself have unique programs.

very useful, notifications add value , no interruption created meanwhile your are in meetings, remote control in case that you need to open an application, application like health care will also get conscious about time sitting or walking for health sake , price is fare based on alll bennefits in your wrist

Additional Options

Currently all the designs reflect a more masculine style. It would be nice to have something like a rose gold to reflect a feminine style.

Exactly what i was waiting for
Rating: 5
i owned galaxy watch and i loved it except it was little too heavy. also, i do not like fitness type watches, so i was literally waiting for watch3. super light, works well with bixby, samsung pay, and a lot of customization you can do. i always wear watch to track my sleep, and it didnt bother me at all. at last, watch trade-in was really good promotion!

Familiar but lighter
Rating: 5
i'm happy with this. it's the best upgrade from my gear s3 frontier. feels the same but lighter in weight. only drawback is the strap cause it felt a bit cheap. i got myself a silicone strap for it later on.

Perfect
Rating: 5
i got this as a replacement for the 41mm size, which was too small. the bezel on the 45mm actually seems shorter than in the 41mm! it's easy to use (both the bezel and the touch screen). the battery life is superb. the screen is beautiful. and since i had a trade in (active 2 - no bezel - good riddance), the price was great, too.

Gr8 watch, superb gizmo,fitness kit not 4 every1
Rating: 5
this is as beautiful and functional watch, phone, info pod, music player, gadget, companion and alarm as you could want, worth every cent. the learning curve is minimal if you can find your way around a smartphone. but the fitness stuff, which is touted as the centerpiece of this timepiece's acumen is just for gym rats or runners and such. i garden, walk dogs, putter around the house, dance now and then and the watch's workout detection for my everyday regimen is quite confused and almost useless. for everything else it does, and there's a lot of it and the sheer snazz of it, i love it. i'd give it a 4.7 but you can only rate in whole numbers.

Great integration with smartphone
Rating: 5
this watch seamlessly integrates with my s20 ultra and i love how i can receive notifications from all my apps on the watch. i get about 2 days worth of battery life with normal use and the always-on display turned off. best surprise so far is being able to connect to my ultra's camera and see it on my watch face and take pictures!

Great watch - so so battery life.
Rating: 4
Upgraded to the Galaxy Watch 3 from the original Galaxy Watch. Love the larger screen. Love that it's slightly slimmer. Love the new sensors, including Blood Pressure Monitoring (Not officially activated in the US yet, but there are workarounds available). Only complaint is that I'm not thrilled with the battery life. Still easily get a full days worth of use even with sleep tracking, but nowhere near the life compared to the Original Galaxy Watch which could push 3 days.

Best looking watch on the market.
Rating: 3
the design is flawless and the rotating bezel is infinitely better then the touch one on the active 2. i am used to the subpar battery life when compared to let's say a versa 2, so i don't really fault it much because the tech and os is muchhhh better then fitbit. i can't excuse away the slow charging however. it is brutally slow and for this amount of money it is inexcusable.

Just Ok
Rating: 3
i regret upgrading from the galaxy watch as there is nothing worth the expense for this watch. the extra stuff they mentioned like the workout, sleep, etc., not that great. the other watch i had was better in doing my every hour stretch reminder this one is weird, it's a hit or miss. the few things i love about this watch are the lightness and also the look on the screen. bigger and aesthetically more pleasing. battery is fine as well, get two days or so. i don't think it is worth it and when i trade in i realized i should have kept my watch.

Disappointing new design and Wear App
Rating: 1
the protruding watch buttons on the right side is poor design if you want to wear the watch for road biking and during circuit training with weights and especially push-up. my s3 is much better with recessed buttons. i am returning it until they learn to get feedback from actual athletic customers. also, what's wrong with their app design, why does it have to combine the watch and phone steps? i want to be able to just use the phone or watch, not the cumulative, which could be double sometimes or 70% to 30% and the 30% is probably already in the 70% of the number shown. makes no sense at all, separate them out. don't buy this if you are going to use if for active life, go with fitbit or some other device
