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.

Good looking smart watch, light weight and best buck for your dollar especially the rotating bezel beats the new Samsung galaxy ultra 8 plus save yourself some cash ..My getting a refurbished from Amazon was very worth it .. Battery life is a task like most quality smart watches you have to tweak the system settings to achieve a balance to your liking

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.

Works as if it were new. TONS of features and available apps. The Samsung health app connects easily and is comfortable to wear all day. P.S. sanitize your watch at the end of each day. All the sweat and grime build up your watch can take a really ugly turn if it's isn't sanitary.

Has a lot of great features but not too many. You can track activities by steps, time, and distance and you can also get your heartrate and oxygen rate. Plus get notification of calls and emails and texts and can read texts. Mileage and step counters seem to be quite accurate. All that for a great price compared to Apple and other products.

Me encantó ,cumple con todo lo que dice y es muy útil ,yo se lo regalé a mi papá y le encantó

Love this watch even though it was refurbished or whatever it came in great condition only had a few fingerprints on the bottom of it and it looks so cool when I'm driving at night and it's lighting up with my speedometer

Not too bad. I thought this was a LTE version but guess I clicked won't one. Shape was decent.

J'aime beaucoup cette montre. La différence entre bon et excellent je crois que c'est le fait que excellent,il y a des chances qu'elle soit neuve. Très heureuse surtout pour le prix.

Excellent quality, it was like new! Will definitely buy from the renewed store again. Very impressed.

Tal cual se describe en la publicación, puedes ahorrarte un dinero por el producto sin perder prestaciones del mismo, al principio estaba un poco lento, pero era por la falta de actualizaciones del mismo una vez actualizado problema resuelto, llego con unos pequeños rayones en el bisel pero eran casi imperceptibles a simple vista, simplemente muy buen reloj, gran compra.

Uno tiene el prejuicio de comprar Renewed, sin embargo, ya se me creo estilo de vida y nunca me han fallado, en este caso el Galaxy smartwatch 4 classic, no fue la excepción, con una mejor batería que alcanza las 48 hrs ( muy bajo aun, pero mucho mejor que modelos anteriores ), calidad de imagen y sonido excepcional.... Muy buena compra

* ACTUALIZACION 23 DE ABRIL 2024: A poco más de 3 meses de uso, eh de decir que sigo considerándolo una muy buena compra. Personalmente lo uso todos los días, todo el día, me monitorea el sueño muy bien y también el ritmo cardíaco en todo momento. El conteo de pasos es algo preciso en muchas de las veces, pero luego en el gimnasio, especialmente en la caminadora no concuerda la información que me da en la caminadora y tengo que estar editando la distancia final recorrida (las caminadoras del gimnasio al que voy solo pueden compartir información con los Apple Watch). Fuera de eso la verdad es que estoy muy contento con este Samsung Galaxy Watch, tal vez el único punto que queda a deber es en la batería que tengo que cargarlo al menos una hora luego de llegar del gimnasio a medio día, y luego otra hora más antes de irme a dormir, porque si no no llega a poder medir el sueño y luego irme al gimnasio en la mañana, y luego llego del gym y ya trae un 15 o un 10 porciento de pila. Lo padre es que con esa hora que lo pongo a cargar llega a unos 70 a 75 porciento y eso me basta hasta las 9 de la noche que lo vuelvo a cargar en lo que ceno y me queda en un 85 a 90 porciento listo para medir el sueño y el gimnasio al día siguiente. Por último, hasta me baño, lavo los trastes, y el carro con el reloj puesto y no tengo ningún problema ni con el audio de las notificaciones, ni con la pantalla, etc. Espero me dure al menos poco más del año, pero hasta el momento siento que sigue siendo muy buena compra. Siendo honesto ni por la mente me pasa comprar el watch 6, este modelo hace muy buen trabajo aun. ........................ Al principio estaba algo un poco preocupado porque veía algunas reseñas malas y otras pues no tanto, pero que como quiera eran de preocupación, pero creo que también tiene mucho que ver que la gente que le llega el producto bien y sin problemas no suele mandar una reseña, simplemente sigue con su producto sin más ni más, en fin, respecto a el reloj, tengo que decir que llego en EXCELENTES CONDICIONES y un poco antes de lo esperado. Si estas buscando un reloj con buenas prestaciones, económico y que se vea muy bonito y elegante, este es el reloj indicado. Y te recomiendo comprar la correa de acero (la cual no viene incluida) simplemente se ve espectacular 👌 vale mucho la pena. Apenas me llego y luego luego hice la reseña, creo que haré otra al mes o dos meses de uso y actualizare que tal me ah ido, de momento el paquete llego mucho mejor de lo que esperaba, muchas gracias Amazon.
