Review: Great watch! Terrible band! - Ok, everybody has terrible bands these days, so I am deducting no points. The band in the picture is the Hēmsut leather band you can get separately. I am converting from a Fitbit Versa 4 that has served me well, but I did it a battery injury while in a hospital bed FOR 2 MONTHS and it now needs to be charged daily to log my heart rhythm and SpO2 levels, which is too easy to forget. I need the hourly logs to have with me for cardiologist visits as we monitor my artificial heart valve, 20 years old and still running! The T-Rex Ultra is OVERKILL for what I want, but I was after the battery life and water resistance (I’ve murdered a couple watches in a swimming pool, finding that “10m water resistance” doesn’t compete with dive ratings) which it covers across the board. I charged it when it arrived, then had to run through 3 firmware upgrades to get to the current OS, Zepp OS 4. That was 3 days ago. The watch, despite having hourly testing on, WiFi active, and live Accuweather running, still has 76% left on the battery. That’s awesome! A lot of the workout tools I have only poked at, not put to use fully, but I am recovering from muscle atrophy following my hospitalization. When the weather warms up, the pup and I will be putting it to use and if there are issues, I’ll come back and add it. Overall, considering I was looking at a Garmin watch for 3 times the cost, I’ve compared capabilities between it (my close friend owns it) and the Amazfit holds a dead even rating. That says a lot! Thus far, I’ve banged the glass into my guitar and the inside of my server with absolutely no scratching. The steel frame helps. Overall, for health needs, I can log everything in Apple Health on my iPhone, export to a spreadsheet in Google Docs, and have detailed info for my docs when I have appointments. I couldn’t ask for better usability. 100% cat compatible!
Review: Excellent smart watch - First of all, I am a previous iWatch person. I have had three, my last being the iWatch ultra. I purchased iWatches for the features, heart rate, exercise, etc. I was never happy with the square shape, but I used it to monitor my activities, sleep, heart, oxygen. I was never happy with the battery life, I was having to charge every day. Then I purchased this watch after doing some research. It does everything the iWatch does, but in my opinion better. It looks great and it is very dependable and rugged. The battery life is great. For example, I charged my watch four days ago and I am at 75% now. I would highly recommend this watch.

## Questions & Answers

**Q: So; first on the market was the amazfit pro; then cames out the amazfit pro-2 and now the newest is the amazfit pro ultra?**
A: The very first model for the T-Rex line is the T-Rex and in the order after are T-Rex Pro, T-Rex 2, and T-Rex Ultra. 

Michael | Amazfit Support

**Q: Any reviews about the pro ultra? i only found from the pro and the pro-2. the ultra price is twice of the pro 2 so i want to read opinions from users**
A: I like it better than my 300 Dollar watch but it has no sound, the watch has a listen to music option but you can't.

**Q: Que diferencia hay , entre el t rex pro 2 y este reloj ??**
A: Eso no lo sé pero son los mismos en la descripción del reloj está está ha salido muy bueno lo mejor es la duración de la batería

**Q: Why is the t-rex ultra so expensive? the additional build quality and minor features simply don't justify the high expense**
A: It's a bit more rugged and capable of tougher use. The price point is really up to you.  I went with the T-Rex 2 to get to a price point I thought was more feasible.

### ⭐⭐⭐⭐⭐ Indestructible Value. Highly Recommend.
*by W***N on April 13, 2026*

Purchased and used the original Ultra for 3 years. Works great, no scratches. I tend to use it for everything ... hike 10k each day, swim with it, bike, sleep with it. The battery is good enough to handle full bio and GPS tracking for a few days (about 2 hours a day) before I put it on a charger while working. I travel a lot, and have worked/hiked with it in Africa, Europe, on construction projects in the Middle East and the Caribbean. The Zepp app does a good job of tracking my sleep and active progress, ... I have an Amazfit scale that captures other metrics it integrates. The data syncs well with my Strava, Training Peaks and other apps. The watch has low power bluetooth and connects directly with my Favero Assioma bike pedals. The monitoring and navigation tracking is accurate enough ... not as good as when I had separate heart, cadence, bike computer, gps trackers, ... BUT I would never go back to using all those different kits for run, or bike, or swim when a single watch handles it all.
