The Amazfit T-Rex Pro, the GTR 3, and the Ares: Deciding Which Outdoor Wearable is the Best for You

Those looking for a high-quality outdoor smartwatch will find a variety of options to choose from with Zepp Health. In this post, we explore a number of potential alternative courses of action.

The Amazfit T-Rex Pro is an example of one of these watches. It was released in the spring of last year and was a somewhat improved version of the original. This watch was developed specifically for explorers because it can resist nearly every imaginable condition.

Next is the Amazfit Ares, which will become available in May 2020. Ares was constructed with longevity, just like the T-Rex Pro. They do not ignore the fact that they share quite a few parallels.

The GTR 3 and the GTR 3 Pro are now the most current items to be added to this list. Both of these products were released during the past few weeks and are part of one of Amazfit’s most successful ranges.

If you are interested in purchasing an adventurer’s watch, you may be debating between the T-Rex Pro, the GTR 3 range, and the Ares. Which one is best for you? All of them stand out as potentially fascinating courses of action. Keep reading to find out just how precisely they vary from one another.

Design and Hardware Comparison of the Amazfit T-Rex Pro, the GTR 3, and the Ares

Appearance and Feeling

The Amazfit Ares and the T-Rex have entirely different appearances. However, they are very similar in many respects.

The first one is shaped like an octagon and has three actual buttons on the right side of it. The watch does not have the T-Rex Military Certification, but it can still withstand the majority of adverse conditions.

The exact measurements of the central unit are 46.5 mm on the long side and 55.5 mm on the short side. The device is made entirely of polycarbonate, contributing to its light weight of just 48 grams despite its relatively large size. Additional features include a 1.28-inch display protected by Gorilla Glass and a reflective color screen with a resolution of 176 x 176 pixels.

The T-Rex Pro comes in a shape that is more conventionally circular. On top of a high-strength polymer casing that measures 47.7 x 47.7 x 13.5 mm, there is an AMOLED display with a 360 x 360 and measures 1.3 inches. There are four actual buttons located down the side. The total weight of the watch, with the strap included, comes in at 58 grams.

This is definitely an extremely durable device, which positions it as a challenger to the Garmin Fenix 6 in terms of its toughness. In point of fact, it is certified to the US Military Standard 810g, also known as MIL-STD-810G.

In case you were curious, the primary distinctions between the T-Rex and the T-Rex Pro are the barometric altimeter, SpO2 sensor, and stress tracking features that are added to the T-Rex Pro and improved water resistance and more satellite location choices. This is a fantastic improvement that builds on previous ones.

We now move swiftly on to the Amazfit GTR 3 model. This one is slightly slimmer and lighter than the T-Rex Pro and Ares but has almost the exact overall dimensions as those two. It also has a body made of aluminum alloy, which gives it a more upscale appearance.

Another thing that works in favor of the Amazfit GTR 3 is that it has a large AMOLED display that is quite clear. This display, which is among the displays of higher quality we have seen thus far on a wearable, is undoubtedly the standout feature of this product. The GTR 3 comes with a 1.39-inch display that has a resolution of 454 by 454 pixels. The display on its older sibling was 1.45 inches and had a resolution of 480 pixels by 480 pixels.

Both the GTR 3 and the GTR 3 Pro contain just two buttons, in contrast to the other two. Nevertheless, one of these is a rotating crown that provides a smooth interface for navigating through the menus just by tilting it. One can find this crown on some models of the Xbox One.

Proceeding on to water resistance, it should be noted that all of these gadgets are adequate in this regard as well. Because they have an excellent water-resistance rating of 5 ATM, you are free to take them on a swim with you without worrying about damaging them. This is even more astounding when considering that the Amazfit T-Rex Pro is suitable at depths of up to one hundred meters (10 ATM).

The Engine Compartment

The Huami Biotracker PPG, used for measuring heart rate, is embedded within each watch. The main distinction between the two is that both the Ares T-Rex Pro BioTracker PPG 2.0 engine and the GTRs PPG 3.0 engine are original versions. As you have probably surmised by now, the most recent generation of sensors should provide more accurate readings of both heart rate and other data.

Additionally, there are a few other distinctions to be made. The only one in this group that does not contain a SpO2 sensor is the Amazfit Ares. On the other side, the GTR 3 Pro is alone on this roundup that comes equipped with a temperature sensor.

Every single one of these timepieces features an integrated satellite connection of some kind. This is obviously an essential feature to look for in an outdoor watch. The Amazfit Ares is compatible with GPS and Glonass, the T-Rex Pro is compatible with GPS, Galileo, and Beidou, and the GTRs are compatible with QZSS.

One thing that first comes to mind when we think of Huami watches is their remarkable battery life. If you turn on the GPS, you should expect a significant decrease in the amount of time the battery will last. The good news is that every one of these devices will take care of everything for you. In the most basic setting, these smartwatches will continue to record time for anywhere between 12 and 21 days. The GTR 3 has the most impressive performance of the bunch.

Comparison of the Amazfit T-Rex Pro, GTR 3, and Ares, in Regards to Tracking Activities and Intelligent Characteristics

Monitoring of Physical Activity and Health

There isn’t all that much of a difference between these gadgets in terms of the actual functionality that pertains to fitness and health. The outcome will depend on relatively minor details.

Since Huami’s unique operating system is used in each of these smartwatches, the menus, movement, and mobile applications are identical. On the other hand, the GTR 3 and GTR 3 Pro employ an operating system called Zepp, while the other devices use an operating system called Amazfit. Because we have experience with both, we are able to say that there isn’t all that much of a distinction between the two. Both are functional, although Zepp OS operates more fluidly and promptly than the other. Additionally, it provides support for applications developed by third parties; however, it will take some time for a selection of these applications to become available.

On the T-Rex Pro, GTR 3s, and Ares, you can monitor your heart rate, sleep patterns, and other essential aspects of your activities. As was just discussed, Ares is really the only one who does not have the SpO2 sensor that monitors the amount of oxygen in the blood. In addition to that, it does not monitor stress around the clock.

A user can take spO2 readings on-demand with the T-Rex Pro, but the blood oxygen sensor on the GTR and GTR 3 Pro has been improved to take measurements automatically. Because of this, the functionality is significantly enhanced in its usefulness.

The GTR 3 Pro also features a temperature sensor, which is the second key distinction. It monitors your skin temperature, which could be beneficial at this time of widespread coronavirus infection.

Keeping a Score in Sports

When it comes to tracking athletes in sports, there are also some variances.

To begin, there is the Ares model, which offers support for seventy different sports modes as well as a few different Firstbeat performance measurements to assist you in enhancing both your performance and your recovery. When it comes to accurately track outdoor activity, having a dual satellite positioning system can be helpful. In addition to that, Huami’s PAI health evaluation is already incorporated.

Users of the Amazfit T-Rex Pro can select from one hundred distinct sports, many of which are common types of outdoor activities. Vo2Max, Training Load, Recovery Time Advisor, and Training Effect are the many performance measures that Firstbeat provides (Aerobic). As a result of the integration of BeiDou and Galileo assistance, the location of the satellites is significantly improved over that of Ares.

Last but not least, the GTR 3s take this one step further. They are not very different from one another in terms of performance measures; nonetheless, the watches increase the total number of sports modes to more than 150. There are eight of these that have auto-recognition capabilities. The most recent iteration of the BioTracker engine should result in more precise tracking of the user’s heart rate. The same can be said for the connectivity provided by satellites, which is improved with the inclusion of QZSS capability.

Intelligent Functionalities

You also get the standard innovative features on all of these, such as getting notifications, managing your music, checking the weather, and much more. The operating system is intuitive and performs admirably in all aspects. On the other hand, Amazfit GTR 3s makes some headway with NFC for on-the-go payments; however, this functionality is only available to Chinese residents. Additionally, they are the only watches that are compatible with Amazon Alexa.

It is essential to highlight the fact that GTR 3 Pro is the only version that includes offline storage for songs. It is necessary in order for it to allow you to transfer songs to the device (the music storage capacity is 2.3 GB, which is sufficient for up to 470 MP3 songs). As a result, the watch incorporates both a speaker and a microphone within its design. When it is connected to a smartphone, this also enables it to make and receive phone calls. Additionally, it is the only one on this list that offers connectivity through WiFi.

The Bottom Line on the Amazfit T-Rex Pro, the GTR 3, and the Ares

The appearance of each of these timepieces is distinctive in its own way, yet their internal workings are primarily analogous to one another.

GTR 3 is the easy pick if you want to project an image of sophistication. It is lightweight, has a luxury appearance, and comes with a rotating crown in addition to having a magnificent high-resolution AMOLED display. In addition, it features the most recent generation of the BioTracker engine, continuous readings of SpO2, improved satellite communication, and an updated operating system version.

Taking this one step further, you should consider getting the GTR 3 Pro. You will receive offline storage for your music as well as a temperature sensor in exchange for the modest price increase.

The T-Rex Pro is a timepiece that can withstand the harshest conditions. Because it is certified to the US Military Standard 810g (MIL-STD-810G), it can withstand most adverse conditions. Those who are searching for nothing more than an outdoorsy watch need to go no further than this option.

The Amazfit Ares features the style and display quality that is the least impressive. However, it has seventy different sports modes, a few different Firstbeat measures, and the most affordable price.
