Amazfit T-Rex Ultra Tactical Smart Watch for Men 47mm, Military-Grade Sports Watch, Dual-Band GPS, 20-Day Battery, Android & iPhone, Black

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!

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.
