Six differences that separate Amazfit T-Rex 3 Pro vs Balance 2

Zepp Health has recently launched the T-Rex 3 Pro. Along with Balance 2 it lands in the premium category of the company’s lineup. But while they share a lot on paper, these two watches are built for different types of users. One leans into outdoor toughness and exploration. The other walks the line between lifestyle and sport. In this article we delve into all the differences.

So what actually sets them apart? The T-Rex 3 Pro brings a brighter screen, titanium parts, a built-in flashlight, and some extra navigation tools that make it more capable off the grid. The Balance 2 keeps things sleek and smart with a lighter body, more storage for music and dual speakers. Both are feature-packed and run Zepp OS 5 with BioCharge, but the way they go about things couldn’t be more different.

Let’s delve into the detail.

Build quality adds refinement to rugged

For starters, the T-Rex 3 Pro upgrades the core design of the regular T-Rex 3. So it’s still a rugged watch. But the Pro model adds a titanium bezel and buttons, sapphire crystal glass, and dual-size options – 48mm and 44mm. It’s a noticeable step up in materials, and the sapphire makes it more scratch resistant.

Balance 2 already had sapphire glass, but its aluminum alloy frame and thinner case make it feel more wearable day to day. It wears smaller despite offering a similar display size, and it’s lighter too.

Both are rated at 10 ATM and include support for scuba diving down to 45 meters. The Balance 2 is slightly more discreet. The Pro is unapologetically bolder. And thicker.

Weight differences are minor but still relevant. The Balance 2 is the lightest at 43g. The T-Rex 3 Pro 44mm is 46.8g. The 48mm Pro hits 52g. All are more wearable than the original T-Rex 3, which came in at over 68g.

Display gets a brightness bump

As far as display tech, both watches use AMOLED panels with excellent contrast and visibility. But the T-Rex 3 Pro pushes brightness to 3000 nits, compared to 2000 nits on the Balance 2. That’s a an increase that you should notice in direct sunlight.

Screen resolution is similar on the 48mm model. The 44mm version drops slightly to 466 x 466 but still looks sharp thanks to its smaller size. Balance 2 maintains a consistent 480 x 480 resolution on a 1.5-inch display.

All three are easy to read. But if you care about sheer brightness, the T-Rex 3 Pro has the edge.

Flashlight feature adds real-world utility

One feature that sets the T-Rex 3 Pro apart is its built-in LED flashlight. This isn’t just a screen hack. It is a proper light integrated into the top edge of the case, not just the screen set to maximum brightness. The light shines forward, letting you illuminate the path ahead while still viewing the display. That makes a real difference when you are running in the dark, setting up camp or simply trying to move around without reaching for your phone. The flashlight includes three levels of white brightness, a red light option for preserving night vision, a short but powerful Boost Mode and an SOS flashing setting.

Balance 2 does not have any flashlight feature at all, so this is one of the clearer advantages of the Pro model. If you often find yourself outdoors in low light, or just want a light on your wrist that you don’t have to think about, the T-Rex 3 Pro delivers something genuinely useful.

Outdoor navigation is more advanced on the Pro

Both watches come equipped with the latest BioTracker PPG 6.0 sensor array. You get the same 5 photodiodes and 2 LEDs, plus a full stack of environmental sensors. They’re evenly matched when it comes to movement tracking and heart rate accuracy. So no real change there.

The real win here is durability. T-Rex 3 Pro inherits the 45-meter scuba mode and 10 ATM rating from the Balance 2. That’s an upgrade over the original T-Rex 3, which did not have scuba support. Military certifications remain part of the T-Rex identity, but the Pro model’s titanium shell and upgraded water rating close the gap with Balance 2’s polish.

There are some differences, though, to do with outdoor navigation.

The Balance 2 includes full offline maps with base mapping, contours, ski resorts and turn-by-turn navigation. That covers the essentials.

T-Rex 3 Pro goes further. You get all of the above, plus support for POI search, route planning, round-trip routes and auto-rerouting. This means you can plan an adventure from the watch, re-route if you go off path, and even generate routes automatically. That extra flexibility is a genuine advantage for outdoor use.

None of this is available on the standard T-Rex 3, so the Pro model pulls ahead in this category. Granted, some of these features might come to other watches via firmware updates.

Battery life is solid on both but depends on the model

Battery life has never been a problem with Amazfit watches due to the lightweight operating system. The 48mm T-Rex 3 Pro delivers up to 25 days of typical use. GPS use brings that down to 38 hours. The 44mm version lands at 17 days standard and 29 hours GPS. Balance 2 is somewhere in the middle, promising around 21 days for typical use and up to 67 hours in power-saving GPS mode.

That gives the Balance 2 a slight advantage if you spend long hours outdoors with GPS enabled. On paper, it lasts longer in endurance scenarios, especially with conservative settings. But both watches are more than capable of lasting multiple weeks on a single charge.

If GPS battery is a priority, the Balance 2 holds its own. Otherwise, the Pro edition’s efficiency improvements mean you won’t be charging often either.

Audio and smarts lean toward Balance 2

When it comes to smart features, Balance 2 still leads the pack. It has dual speakers. The T-Rex 3 Pro includes one speaker and a mic, which gets the job done. To remind, the vanilla T-Rex 3 variant does not have a speaker – only a mic. So there has been an upgrade there.

Music storage caps at 26GB on the Pro, while the Balance 2 offers a bit more room with 32GB. Both support Bluetooth playback and offline storage.

Both watches now run Zepp OS 5.0 with BioCharge, so the software experience is very similar. That means smooth animations, better haptics and more fluid app support.

Which one makes sense for your wrist?

If you spend most awake hours in rugged terrain, rough weather, or simply want a watch that feels like it can survive getting thrown in a backpack and dragged through the woods, the T-Rex 3 Pro makes sense. The flashlight, offline maps with auto‑rerouting, POI search, and titanium parts add up to real utility, not just spec sheet fluff. For those who already liked the regular T-Rex 3, the Pro model improves your adventure toolset.

But with that utility comes a higher cost. The T-Rex 3 Pro starts at around $399.  That means you’re paying a premium for durability, torque in features, and rugged styling. If those extras don’t matter much to you, you might find better value elsewhere.

Balance 2, priced closer to $300, gives you most of what many users will need: solid tracking, good battery life, dual speakers, along with a lighter, more discreet build. It lacks the flashlight and advanced navigation features of the Pro, but for everyday use and mixed routines (gym, office, travel), it likely fits more wrists and more budgets.

If your budget allows for the Pro without regret, and you expect to use the outdoor and illumination features often, it might be worth spending the extra. If not, the Balance 2 gives you a lot of functionality for less money, while still being tough enough and smart enough for most people’s lives.
