Amazfit smartwatches have expanded the T-Rex 2025 lineup and belong to the class of rugged wrist gadgets ready for various adverse operating conditions. Within the proprietary model range, this is an advanced gadget, and overall, it can be considered a representative of the mid-price category. The durability and shock resistance of the model are confirmed by compliance with the MIL-STD-810 standard and the presence of sapphire glass that resists scratches.
Furthermore, it features an enhanced water resistance of up to 10 atmospheres, allowing not just swimming and water sports but also diving or spearfishing. The Amazfit T-Rex 3 Pro 44mm smart watch operates on the proprietary Zepp OS, features a 1.32-inch AMOLED display with a maximum brightness of 3000 nits and a clear picture (resolution of 466x466 pixels). Important advantages of the model include a full-fledged flashlight, an improved positioning system with a Dual GPS navigation module, track navigation function, maps, and a compass.
Also noteworthy is the support for Bluetooth calls, and the presence of a large number of fitness modes (187 in total), the calculation of VO2 Max, as well as all the usual sports activity and health metrics. The 500 mAh battery should ensure up to 17 days of autonomy under normal usage scenarios and from 2.5 to 8 days under intensive loads, including active GPS usage.

Once I had experience using devices from this brand in the form of the first generation Bip, which held a charge for 50 days. After a bitter experience with a watch from Samsung and without the budget for a Garmin, I decided to choose this model. I was looking for good battery life (charging every day for an hour and a half isn't for me), a large screen, sapphire glass, and the ability to talk through the watch. I also wanted a rugged design because I really dreamed of buying a Garmin Fenix and was looking for something similar. So, the first thing that caught my eye was that the watch is large, quite massive indeed, thick and has a robust rugged design. I was worried that it would be too big for my rather thin wrist, but I chose primarily for the large battery and was ready for it. The upper part and buttons are titanium, the glass is sapphire, and everything else is plastic. I thought it would feel cheap, but I was wrong - the watch is almost unnoticeable on the wrist, comfortable to sleep in, and doesn't turn into a cold generator in freezing weather (hello Samsung). The display is high-quality, rich, and bright, with automatic brightness adjustment that works adequately. There is a winter mode and button control. The system itself after Samsung just flies - it's some kind of miracle. There are so many settings, everything can be customized precisely to your needs. The branded software is top-notch and allows you to monitor health and workouts. You can download maps directly to the watch and plot routes in it - the sports functionality is top-level. The battery with AOD and all health tracking lasts 10 days. Charging - just a small unit with a USB-C port and contacts, it's easy to lose. The design is specific, and you need to make an effort to find a compatible strap.  Olexandr Cherkashchenko: use Amazfit T-Rex 3 Pro 48mm less than month |

Popular questions about Amazfit T-Rex 3 Pro 44mm
Is the flashlight here a real flashlight or just a bright screen?
The Amazfit T-Rex 3 Pro features a dedicated LED flashlight rather than a white-screen mode. It can be used to illuminate a trail, lock, or belongings in the dark; white, red, and SOS modes are available.Source:SpecificationsExpert reviews
Who are they really suitable for?
This is a good choice for running, hiking, swimming, and regular activity tracking. The watch focuses on navigation, sports metrics, and long battery life; if a wide range of apps and full smartphone-level capabilities on your wrist are more important, the interface may seem rather basic.Source:SpecificationsExpert reviews
Can I make calls and listen to music without a phone?
Bluetooth calls are available right from your wrist thanks to the built-in microphone and speaker. You can store music in the watch’s memory and listen without a phone, but the familiar Spotify app isn’t available here—for streaming, you’ll need to find another option.Source:SpecificationsExpert reviews
Can I swim in a pool?
Yes, the watch is suitable for swimming and has 10 ATM water resistance. There is a dedicated swimming mode, so you can record a pool workout instead of simply wearing the watch without tracking your activity.Source:Specifications
How long does the battery last?
In standard mode, up to 17 days of battery life are claimed on a single charge. With GPS, the battery life is noticeably shorter: up to 60 hours, and up to 26 hours with enhanced accuracy, so for long, multi-day routes it is best to plan charging in advance.Source:Specifications
How useful are maps and GPS on hikes?
For routes beyond familiar roads, the available features are sufficient: there are maps, track navigation, a compass, an altimeter, and dual-band GPS. You can download offline maps, plan a route, and receive turn-by-turn directions; if you go off route, the watch can reroute.Source:SpecificationsExpert reviews
Are they comfortable on a small wrist?
the 44 mm version does not look excessively heavy: it weighs 47 g and is 13.2 mm thick. The case still has a substantial design, but this size is noticeably more comfortable for active movement and everyday wear than larger rugged watches.Source:SpecificationsExpert reviews
