Great watch so far.
David H.✓ Verified PurchaseOctober 9, 2023
I like that its so tough. I work hard and play hard so I need it to keep up. So far the only thing I didn't like was when they say music control in the description they didnt say it wasn't capable of playing through the watch. My only complaint.....
Not overcomplicated, and for a guy who just wants a nice-looking and capable watch; this is it
Richard✓ Verified PurchaseSeptember 13, 2023
Ok, not a super in-depth review on an extremely capable watch here, but after two months of use, here's the review.

It's awesome.

I had a Luminox Recon (non-smart watch) for 10 years that I literally NEVER took off. Lost it in a lake because bands really never stayed on that well. So, with a wristwatch literally being an extension of my personality and my "look"; I stressed the hell out. I didn't want to jump on the smartwatch bandwagon and just wanted a simple good looking and tough watch to glance at the time, time my workouts, and let me know what date it was without costing me over $300. Couldn't find one that I thought was worth the price of admission. I purchased a couple of watches (Amazfit T-Rex Pro and a Suunto watch) to try out for a couple weeks and hopefully decide on one. The T-Rex Pro won.

There's waaaaay more capabilities here with this watch than I've even delved into, but the things I love about it are as follows:

1) Looks - this thing looks baddass. Not too big or small on my wrist. I was, surprisingly, able to find a watch face that I loved and looked extremely similar to my Luminox. Yeah, it cost an additional $1.99 in the app store, but awesome!
2) Sturdy - I've knocked it around a bit since I never take it off, and it is holding up better than I thought so far. No scratches or dings (buy yourself a screen protector anyway). I especially like how the pin that holds the watch band on is a "through-design" pin instead of a compression pin. These pins on the T-rex are screwed on, so I don't have to worry about the watch band falling off again unless the rubber band itself breaks or deteriorates. Also the single band keeper that holds the tail of the unused band is great; it has a ridge in it that sinks into the watch band adjustment hole so that it stays in place and holds the tail of the band securely.
3) Comfort - more comfortable than my Luminox rubber wrist band. This wrist band has way more holes for adjustment which I appreciate and the band is a bit stretchy/flexible. It actually feels good on my wrist.
4) Capabilities - I track my workouts, and it's super awesome that the watch now tells me what my heart rate is within fat burning/aerobic/anaerobic levels when doing so. Super cool. It also has great tracking abilities with the limited amount I have used them (sleep for instance). It's actually helped me with either picking up or dropping my intensity of workouts in a positive manner. I only have to charge the watch every 7 days; and it takes just a little more over only 1 hour to fully charge the watch. So good! My wife is so mad her Samsung watch basically needs to be charged every single day.
5) App - the app is cool and informative and comprehensive. One complaint is that for the weather info to show up on my watch face I have to connect the watch to the app. For whatever reason, the weather info stops showing up on the watch face eventually though and I'll have to open the app up again and connect. Not sure if it loses connection or what; seems weird that it stops relaying data to the watch for weather.

Overall, with the limited functionality I use this watch for, I'm way more pleasantly surprised and happy with this watch than I thought I would be as an old-skool analog watch user who fought getting with the times and switching out. Love it.
Amazfit T Rex Pro, Triathlon worthy

This watch is a beast! I agree with many of the reviews listed for this fitness watch. They were the main reason I got the watch in the first place. I have used this watch every day for the past 3.5 months to train for the Xterra Mission Bay Sprint Triathlon that just happened 10/15/2023. It has done a great job of tracking all of my training work outs whether it was HITT, yoga, running (outdoors with GPS or indoors on the treadmill), biking (same GPS quality outdoors) and swimming (GPS kicked butt). I'd highly recommend this for anyone wanting a watch that can keep up with a tough training schedule and maintain great sleep data. The EPOC measurements are pretty spot on and the Zepp app is really cool and informative. I was able to tie the watch to my Peloton workouts along with Strava and the Lose It! app for counting calories to keep me on track. This watch is pretty amazing especially for the fact that it doesn't cost $800 :)
My opinions are my own. This is NOT a sponsored review...

I specifically ordered the T-Rex Pro b/c of the grey color scheme. The light grey strap and case, dark grey bezel and blue indices gel so well together. It is, by far, the classiest of the bunch. And that includes other variations of the T-Rex line.

The watch is surprisingly light. You may guess that when you pick it up, the 'quality' isn't there. This is a throwback mentality from a bygone era. The truth is that material science has advanced far beyond the buzzword materials of the jet age. You don't need a hunk of steel on your wrist anymore. The sensors that read your biometrics don't care. And if the watch case happens to fracture from the insane 'mil-spec' pressure that was put on it, guess what, it was on your wrist... and you need to be going to the emergency room.

All to say, plastic, properly composed and formed, can withstand far more pressure than your bones. Be grateful that we live in this time. And enjoy the light weight that this timepiece offers.

The display is easily the most important aspect of the modern watch. The Amazfit does not disappoint. The AMOLED is sharp and with deep contrast. There is zero to complain about in that department... The ambient light sensor, however, is a little slow to respond. In a dim setting, it takes a little longer than, say, an Apple Watch, to bring up the brightness level. So to the Amazfit engineers I would say, "This is a very simple comparison."

The buttons are tactile, easy-to-feel and press. The knurling is perfect. Don't change a thing.

The graphics portion of the SOC are perfectly adequate to drive the display with fluid motions and zero lag. I don't feel that the watch is generating any heat or struggling to keep up. It's a testament to how far microelectronics have come.

Which brings us to the elephant in the room; battery life. In short, the battery life is exceptional. It lasts so long that, at some point, you feel that you need to charge it 'just because'. The watch reminds me of cell phones from the olden days, when your Nokia 5100 would go for weeks between charges. Can we please get back to that??? Anyway, thank you Amazfit. You delivered on this in spades.

I bought this watch when the T-Rex 2 and Falcon were available. The Ultra was also just announced (at the time of this writing). While I would be happy to review any of those watches, I would urge Amazfit to consider one thing; develop your software. As is stands, your software is adequate. But in order to lead in this segment, the software has to take priority above all else. Titanium bezels and more bolt faces don't move the needle. Well-considered and well-developed software does. I hope you're listening.
One of the most impressive smart watches!

I used a Fitbit for the past few years but when it broke, I knew it was time for a new look. I had recently purchased an Amazfit Band 7 for my daughter and I really liked how user friendly it was, color display and how fast it charged so I thought I'd find myself a similar one but for someone like me that hikes and does trail running. After extensive research on not only Amazfit but Garmin, Samsung and other "budget" brands on Amazon, I finally went with the T-Rex Pro. The price was just right, not too expensive to justify on a smart watch and not so cheap that you start to question why it's so cheap. Once I received it, I was instantly in love. The size is 47mm, which is a little bigger than I wanted but the T-Rex 2 is 42mm and thats just too small for me. It's incredibly lightweight, almos to the point you cant feel it but with the 47mm diameter you know its there. The display is bold and crisp and the dial interface is very responsive which was a big factor for me. The wrist wake up feature is much faster than Fitbit (which drove me crazy with Fitbit). I love the giant library of workouts, including Trail Running, which I didn't notice on many other models. One of the biggest features this has that most in this price range dont have is the GPS function which I really need in the wild. The app is basic and easy to use and I havent noticed any limiting issues with it so far. The charging is incredible! The first day I used my T-Rex Pro I charged it overnight to 100%, I was on it all day the next day, changing faces, changing settings, just doing the most to make it exactly how I wanted it. Hours and hours on it and it only went down to 86%. Here's the kicker, I put it to charge and it was back to 100% in five minutes!!! Seriously a great product and I cant wait to do more with it!
