Samsung Galaxy Watch4 Classic Stainless Steel SM-R890NZSAXAA Description
Samsung Galaxy Watch4 Classic 46mm: The Smartwatch with a Real Rotating Bezel
The Samsung Galaxy Watch4 Classic is a premium smartwatch with a stainless steel case and a physical rotating bezel. It tracks your workouts, sleep, heart rate and body composition. It also runs Wear OS, so you get apps, maps and Google Assistant on your wrist.
This listing covers the 46 mm Bluetooth model in silver, model SM-R890NZSAXAA. Below, we explain what it does well, where it falls short, and who should buy it.
Design and Display
The Watch4 Classic has a 316L stainless steel case. It measures 45.5 x 45.5 x 11 mm and weighs about 52 g. The screen is protected by Corning Gorilla Glass DX.
The display is a 1.4-inch Super AMOLED panel at 450 x 450 pixels (about 321 ppi). Text is sharp, colours are rich and the screen is easy to read outdoors.
The star feature is the rotating bezel. You turn it to scroll through menus, adjust settings and switch apps. It feels precise and works well with wet or gloved hands.
Health and Fitness Tracking
Samsung’s BioActive sensor combines heart rate, ECG and bioelectrical impedance in one module. Together with other sensors, it supports these features:
- Continuous heart rate monitoring
- Blood oxygen (SpO2) measurement
- ECG readings (availability depends on your country)
- Body composition analysis (body fat, skeletal muscle and more)
- Sleep tracking, including sleep stages
- Stress tracking and guided breathing
The watch also records dozens of workout types, including running, cycling and swimming. Built-in GPS means you can track routes without your phone.
Performance and Software
An Exynos W920 5 nm chip powers the watch. It comes with 1.5 GB of RAM and 16 GB of storage. Apps open quickly, and there is room for music and apps.
The watch launched in 2021 with Wear OS powered by Samsung, and it can be updated to newer Wear OS and One UI Watch versions. Check Samsung’s update page for the version your unit supports.
NFC is included for contactless payments. Wi-Fi dual-band, Bluetooth 5.0 and GPS/GLONASS/Galileo/BeiDou complete the connectivity.
Battery and Charging
The 46 mm model has a 361 mAh battery. Samsung’s typical-use estimate is around one to two days, depending on features such as Always On Display and GPS. Treat it as a smartwatch that needs charging every night or two.
Charging is wireless at up to 5 W, using the included charger.
Water Resistance and Durability
The Watch4 Classic carries 5ATM and IP68 ratings. It also meets MIL-STD-810G durability testing. It is suitable for pool swimming, showers and rain.
Compatibility
Compatibility matters here. The Galaxy Watch4 Classic works with Android phones (Android 6.0 or later with at least 1.5 GB of RAM). It does not support iPhone. It works best with Samsung Galaxy phones, where a few features, such as ECG and blood pressure, need the Samsung Health Monitor app.
Who Should Buy the Samsung Galaxy Watch4 Classic?
Buy it if you use an Android phone and want a premium build, a rotating bezel and detailed health tracking. It also suits people who like a traditional watch look.
Consider something else if you use an iPhone, want multi-day battery life, or prefer a lighter watch.

Todo excelente, esta como nuevo y la correa original, para hacer reacondicionado está totalmente nuevo Solo hubo que actualizar como cuatro o cinco veces para que quedara al 100 el único pero es la batería, pero por el sistema que trae es excelente ya le instalé WhatsApp

First time getting a refurbished item. When I got it, the watch didn’t come in its original box. The watch looks brand new came with the wrist band and charging port. I would definitely buy another refurbished watch from them.

Had an issue with the watch I purchased and they exchanged it for me quickly. The one they sent back is perfect!

Cuando lo recibí se actualizo varias veces y se empezó a calentar y me salió un mensaje de la temperatura, pero una vez que terminaron las actualizaciones, todo perfecto.
Para todo lo que ofrece su sistema, la batería dura bien, a mi me dura casi los 2 días, y si le doy bastante uso a todas sus funciones.

46mm suits my wrist well. All functions and range of options one could hope for. Battery life is good as I didn’t want something that would only last less than a day (cough Apple Watch). On normal wear with location and heart rate and sensors on, I get around 30 hours so I can at least charge it while working at my desk. On full battery saver it’ll get me 2.5 days and with configs on for interval measurements of physical data. Bezel function is great makes it easy to navigate things at times when gloves on. Great smart watch.

I am very happy and satisfied with this watch and for multiple reasons. First of all it was a renewed item so I was prepared for it to potentially be scratched up and have all sorts of glitches. This is the second renewed item I’ve purchased from Amazon and the second time I’ve been pleasantly surprised. It didn’t arrive in it’s original packaging but it did arrive in pristine condition.( I forgot to wipe the watch off at the end of the day I took the picture on so the watch face was a little dirty but there are no scuffs or scratches on the watch) It appears that all of the functions of the watch work as they should. I say “appears” because honestly I’ve only ever worn conventional watches before so with all the things that this watch can do I’ve been a bit overwhelmed with it and haven’t been able to fully put it through all of its paces yet. Which leads to the second thing which is that I am quite satisfied with all the things that I can do and have done with it so far. There are just so many options but it’s functioning extremely well so far. The only area I wish was a little better is the battery life. I normally get about 2 days of use before I have to charge it which isn’t that bad, but again you have to remember I’m coming at this as somebody who’s used to having a regular watch that you never have to charge or wind up or anything. Still for all that it does I can totally see why the battery life isn’t the best out there. It has lots of functions and you basically want to use them all lol. It has a beautiful screen and lots of flashy things you can activate on it so it’s worth the trade off to me. And let’s not forget that sweet sweet rotating bezel…lol. I say if you’re in the market, buy this watch with confidence. 👍🏾

Battery life is better than expected for a watch that takes calls. Works intuitively as a fitness and media monitor. Very pleased with this refurbished item. Would buy again. Thank you!

Haven’t tested all its features, but so far so good.
Aaron Richardson –
I bought this to replace my frontier. I chose the refurbished like new and I am pleased. There is no visible damage on the exterior and all the packaging and accessories were there. Only thing was the battery life wasn’t as long as the original, but all in all a solid choice.
FERNANDO MARTINEZ ALONSO –
Watch looks new not even a single scratch. Had a little issue with shipping and their response was fast, it was solved the same day. I would purchase from them again!
Michael T. –
I was convinced my item was broken considering it wouldn’t hold a charge pass 6% and it would overheat preventing a charge completely. The issue was the stand charger it came with was faulty.
I noticed when I used my phone to wireless charge my watch, once it went pass 6% to 10%. I invested in a different charger that was 11.99. My watch is now fully functional, but having the original item the product comes with should be ideal, especially when it’s dealing with proper wattage output.
