The Amazfit T-Rex 3 Pro is a smartwatch built for the outdoors that wants to show you don’t have to spend big on an Apple Watch Ultra 3 to get yourself a good trekking companion.
For a smaller spend than most of the competition, the upgraded T-Rex 3 features a brighter screen than the non-pro version, surrounded by new design materials, while offering features like free color mapping, a flashlight and weeks as opposed to days of battery life.
The T-Rex has been a standout line for Zepp Health’s busy range of smartwatches. Does the T-Rex 3 Pro make big improvements on the 3 to make it worth the upgrade and one of the best mid-range outdoor smartwatches to buy? I’ve had it strapped to my wrist to find out.
Design & Build
- Comes in two case sizes
- Added sapphire glass and titanium
- Now suitable for scuba diving
While the T-Rex 3 Pro sticks to the same octagonal case look as the T-Rex 3, there are some changes. The main one is that it’s now available in either 48mm or 44mm case sizes. They cost the same and you can just expect different sized screens. The smaller model also offers a softer octagonal design compared to the 48mm model I tested.

Another new feature is one we’ve seen Garmin introduce to its smartwatches recently. That’s a built-in flashlight and not one that simply turns the watch screen into an added source of light. It’s located at the top of the watch case.
When activated in the quick settings menu on the watch you can adjust brightness settings with the physical buttons on the left side of the case. There’s the option of white or red color lights and while it’s not quite as bright as Garmin’s built-in flashlight, it offers a useful way to keep you seen on evening outings.
The 48mm T-Rex 3 Pro is a touch thicker than the T-Rex 3 while moving to a bezel and physical buttons made from titanium. You’re still getting some tough metal with a little less overall weight to handle. For a big watch, it’s a pretty manageable one that’s never felt too hulking to wear.

The watch strap remains a 22mm-sized one, though crucially, it is now a bit easier to remove and replace. There’s a quick release mechanism that, while fiddly, does mean you can pop that strap out with the tool you needed for the T-Rex 3. The strap though, did have a tendency to feel a bit sticky under my wrist after workouts. It never made it uncomfortable to wear, but I’ve definitely worn nicer sporty silicone straps.
As this is a smartwatch fit for some rough and tumble, the Pro can operate in low temperatures and safely survive quite a deep dip. It carries a 10 ATM waterproof rating, making it safe to be submerged in water up to a 100-meter depth. It’s also suitable for recreational diving up to 45 meters and is now fit for scuba diving to boost its water sports-friendly credentials.
Screen & Audio
- Brighter screen than T-Rex 3
- Sapphire glass now included
- Added speaker for Bluetooth calls
The 48mm Pro features the same 1.5-inch, 480 x 480 resolution AMOLED touchscreen found on the regular T-Rex 3. It now swaps sapphire glass in place of Gorilla Glass to provide a nice upgrade in protection against scratches.
Sapphire glass is typically found on much more expensive outdoor watches. A more noticeable upgrade is the bump in overall screen brightness. This is a display with a peak brightness of 3,000 nits (up from 2,000 nits) to make an already very easy to view screen more viewable in challenging conditions.

Unlike the T-Rex 3, the Pro does now give you a speaker alongside a microphone. This enables Bluetooth calls, lets you hear updates during workouts and listen to music out loud – If you want to be one of those people.
The speaker certainly prioritizes clarity and volume, which is fine by me and makes it far more suitable for calls than listening to music.
Software & Features
- Runs on Zepp 5.0
- Contactless payment and music player included
- Mixed support for iOS and Android
The T-Rex 3 Pro runs on Zepp OS 5.0, the latest version of Zepp Health’s proprietary operating system. It doesn’t look all that different from Zepp OS 4.0 and is still compatible with both Android phones and iPhones. I’ve been using it mainly with an iPhone, where you’ll need to download the improved Zepp smartphone app to get things set up.

What you get in a smartwatch when you’re not tracking workouts is something that a good array of features. It simply doesn’t match what other smartwatches can offer.
Take a staple feature like notifications, where support for messaging apps, emails, and other apps can vary. You can’t respond to notifications, nor will it pull through images like some other smartwatches can.
