    • Great price, great watch
Size: 46 mm Color: Black
And to think you can buy a top of the line smartwatch from a few years ago that compares to the price of regular watches. I paid 400 when this watch released back In 2021, It got water damage. Then I decided to buy this refurbished watch, it was great but I lost it in a week, but Keep in mind it didnt come with the original cable, but that was okay to me because I still have the original cable from the other watch, and if youre wondering. Yes, it has the same charging speed. So after I lost the watch, I decided to buy it again. Make sure to turn on remote protecting & anti theft, and turn on Location sharing so other people can find your watch if you lose it. And try to keep it away from water if you want it to last you a long time, we dont really know how good that refubrished waterproof seal is, but even my brand new one is bought on release got water damage after a few months, so just keep it away from water if you want it to last a couple years. Final thoughts, just buy it, its 60 and the perfect balance between functionality and price, or you can wait 4 years until today's top of the line Samsung watches sell for under 100, Your choice! ... show more

    • Like These Enough I Bought a Second
Size: 46 mm Color: Silver
I've had a 4 Classic since 2021 and there's enough to like about it that I haven't seen a watch I'd rather have. The battery life is the biggest downside. You can stretch it by running very few of its features continuously, but then what is the point of having it at all in that case? Using all the features to track your personal health journey, it is possible to get nearly full day charges, but you have to time a period of inactivity in which to fully recharge the watch in order to get through the night for sleep tracking and through the typical day. It charges relatively quickly, but this can still be hard to accomplish. Because of this, I bought a second watch here in refurbished condition. My plan is to let my day watch charge overnight while I switch to this watch for sleep tracking and use as a general backup. The Samsung Health App seems to deal with this well so far. I just turn the watch I'm going to charge off, then turn on the next watch. I never charge them while they are on. The condition of the watch was indistinguishable from new. It even came with a charger and a new band. The band is not my favorite, but it isn't uncomfortable either and will serve my purposes well. I looked at a new Watch 7 and Watch 7 Ultra, but even with longer battery life, the main problem that it eventually needs to be charged is not solved. I'm liking the solution of just having two identical watches best. As for the watch itself, I like it a lot. It isn't 100% accurate in all circumstances with all features, but it is close enough to be informative. If you need medical grade information, I'm sure you'll never find it on any watch to date. This is a heavy watch. If you don't like those, this isn't for you. My first Watch 4 Classic has survived over 3 years of use and I work blue collar type jobs. I've been surprised how tough and durable the screen is, mine still doesn't have a scratch. I think the dial bezel, which is a great feature in use, does a great job of adding protection. I got the silver color and it just looks like a classic watch with a modern flair. The grey on the band takes away from the cr hrome a bit. A black band would put more focus on the watch itself. ... show more

Review Image by P.O.P. P.O.P.
Yesterday I received the Samsung Watch 4 -10/2024. I bought it used and it came as expected a few micro scratches nothing important. I paid about $90 dollars for it. The watch came with 66% of the battery and after setting it up (which was easy) I can say I was impressed by the amount of things the watch can do. However, that's as far as it goes right to this point. I charged the watch, after setting it up, to 99% battery. I went to bed wearing it to check the sleep monitor at work. It did work as expected. I slept for about 5-6 hours and watch was at about 40% battery. I did not like that at all. It let me know that in full use I probably will not make it through the entire day. I will update on that today because I got full day of work plus gym workout. A serious, and why the 3 stars, is because Samsung failed to alert people (its watch customers at least) that without a Samsung phone you can not use about 40% of the advertised features in this watch, which as I said before there are lots of them. I have a Motorola Razr 2023 and I can not install the Samsung Health Monitoring app on my phone because it is not a Samsung phone (something that it would have giving me paused to buy it). The Samsung Health Monitoring is preinstalled in the watch but it will not work if not installed on your phone. There are some features that still can be used through the SAMSUNG HEALTH app (not to be confused with the monitoring app which measures blood pressure, glucose and the works). You can install Google Fit which is nice for me since I use it for workouts. I have a Samsung tablet which I use for work, but there you can not install the SHM app either, it is only allowed to be installed in phones. I will give an update in couple of weeks. Update 4 days after purchase. After wearing the watch for couple of days I increased my rating to 4 stars. The amount of customization in this watch is impressive. Connectivity is strong it won't disconnect from my phone easily (one of the problems I have with the Tic Watch that kept disconnecting from my phone and it was a pain in the back while running because I couldn't manage the music) in the Samsung watch it's not happening. Battery life is not the best but with some tweaking at night it can be manageable. Eating only 15 to 20% through the night. Changing take 2 hours from single digit to above 90%. So far I'm happy with the purchase. About the health monitor which is one of my major gripes with Samsung, I spoke to few people that have the entire Samsung platform and the average answer was that health monitor didn't work as good or as expected. Wearing the watch at full power at work and gym, usually 10 to 12 hrs, the watch consumes about 50 to 70% of the battery. So charging it every day is a must. Keep this in mind when buying it. It works for me because I can manage to charge twice a day for about 1 hr. I will update again in a month or so. ... show more

I often purchase renewed items, for one, you have a 90 day warranty, if you are unsatisfied, Amazon will send out an exchange immediately, they will make it right. I have a Samsung Gear S3 Frontier also renewed, excellent condition, but the Doctor said I need to measure ECG, didn't want to spend $200+ dollars, this was $60! Excellent condition, I can't find one minor scratch or blemish, band looks new and even came with an OEM Samsung charger! All features function properly and the battery holds a charge for almost two days! Very happy with this purchase! DLM ... show more
