Quick summary:

Why the T-Rex 3 Pro are interesting at this price point

Amazfit with its T-Rex series has long targeted people who want the look and features of Garmin Fenix-type sports watches without the double price tag. The Pro version has taken this strategy to a new level – compared to the standard T-Rex 3, it adds Grade 5 titanium alloy used in aerospace, sapphire glass on the display, and a built-in dual-color LED flashlight including an SOS mode. At a price of 7 992 Kč, it’s a package you typically won’t get from competitors at this price point.

Key parameters: display, battery life, GPS

At the heart of the watch is a 1.5″ AMOLED display with a resolution of 480 × 480 px and a peak brightness of up to 3,000 nits, ensuring readability even in direct sunlight. For colder days, there’s a Glove Mode that responds to touch through gloves up to 2mm thick. Both the body and buttons are made of titanium, the display is covered by sapphire glass, and the entire device can withstand operation in temperatures ranging from -30 °C to +70 °C, as well as diving up to 45 meters (10 ATM).

The manufacturer states battery life of up to 25 days in typical usage mode, 38 hours in precise GPS mode, and 116 hours in power-saving GPS mode – enough even for an ultramarathon. Reviewers confirm that in reality, the battery life is slightly shorter, but still reaches 17 or more days between charges. Location tracking is handled by dual-band GPS with 6 satellite systems, including Galileo, so accuracy in forests and cities is on par with significantly more expensive watches.

Among the functional features worth mentioning are 180+ sports modes including bouldering, skiing, and HYROX races, the BioTracker 6.0 PPG biometric sensor for heart rate, SpO₂, and stress, the BioCharge Energy Score indicator adopted from the premium Helio Strap, and integrated NFC for contactless payments via Zepp Pay. Data synchronization works with Strava, Apple Health, Google Fit, and Adidas Running.

Practical aspects: calls, flashlight, strap

The watch has a built-in microphone and speaker, allowing you to receive and make calls via a paired phone directly from the watch. Together with the Zepp Flow voice assistant and Bluetooth 5.2 support, this makes the T-Rex 3 Pro a watch that truly works even in terrain where you don’t want to pull out your phone from your backpack. The LED flashlight with white and red light has two intensity levels and an SOS mode – users praise it in reviews as surprisingly powerful and useful, for example, as a blinking light for a morning run.

The strap is 22mm Quick Release, so you can choose from virtually any selection of replacement straps. Zepp Pay currently only supports MasterCard, so Visa cardholders will not be able to pay – this is important to keep in mind if you rely on NFC payments. With its 48mm case, the watch is quite large and robust, but users mention that it’s not felt on the wrist even during sleep, as titanium significantly reduced the weight compared to steel competitors.

What users say

On Alza, the T-Rex 3 Pro has a full rating of 5.0 out of 5 from 42 customers and 100% of customers recommend the product – out of 17 text reviews, the vast majority give full marks. The sample is still small (the watches have been sold since September 2025), but the consistency is above average. People most often highlight the build quality and sapphire glass, very accurate GPS and heart rate measurement, responsive Zepp OS environment, battery life over 20 days, and the fact that the watch “can do everything that models 3-4× more expensive can” (one of the recurring quotes).

However, critical voices also appear despite the 100% recommendation. The most frequently mentioned weaknesses: offline maps from Mapbox are designed more for roads than for spontaneous navigation in the forest – they are sufficient for maintaining direction, but not the best choice for venturing into the wilderness. Furthermore, users point out a very limited selection of watch faces in the Zepp store (only about 4 are practically usable), battery life is slightly weaker than the manufacturer promises, and for some units, problematic installation of the original strap. A few reviewers mention that the sapphire glass easily attracts fingerprints, but thanks to the high display brightness, this is minimally distracting in practice.

When it doesn’t make sense

If you rely on off-road navigation (trail running, wild hiking), Garmin Fenix or Suunto Vertical will provide significantly more usable map data, albeit at a substantially higher price. Similarly, if you pay exclusively with a Visa card, you won’t be able to use NFC payments via Zepp Pay yet. And if you have smaller wrists, the 48mm case might be uncomfortable – Amazfit is also preparing a 44mm version, but it’s not yet in stock in the Czech Republic.

Verdict: at 7 992 Kč, the best price Alza has offered the T-Rex 3 Pro for

The Amazfit T-Rex 3 Pro for 7 992 Kč is one of the most interesting offers in the outdoor smartwatch segment to appear on the Czech market this year. Titanium, sapphire, dual-band GPS, NFC, 25-day battery life, and an LED flashlight in a package that practically has no direct competition at this price point. The fact that this promotion is historically the lowest price on Alza, and that the watch has a full 5/5 rating from 42 reviews, only confirms that the price/feature combination is right. Limiting factors remain maps and watch face selection, but Amazfit is working on both through updates.
