Amazfit T-Rex 3 and Amazfit T-Rex 3 Pro look almost identical, but once you delve into the details, the differences really matter. The Pro packs in upgrades like longer battery life, dual-band GPS, BioCharge tracking, offline maps, and improved durability—making it the better pick for outdoor adventurers.
Both models still carry the rugged, military-grade design, bright AMOLED display, and water resistance that the T-Rex series is loved for. They’re rugged, reliable, and built to handle just about anything. Where the Pro shines is in the extras.
With offline maps, you can explore new routes without your phone. Dual-band GPS gives more accurate tracking, and BioCharge helps you understand when your body is ready to perform or needs recovery. Pair that with stronger durability and extended battery life, and the Pro clearly stands out.

Quick Verdict
Here’s the short version of the differences between the two watches:
- T-Rex 3: The best choice if you want a rugged, no-frills smartwatch with fantastic battery life and all the essential tracking features—without the premium price tag, making it a smart financial choice for the budget-conscious buyer.
- T-Rex 3 Pro: The better pick if you’re a serious adventurer who wants top-tier durability, a brighter screen, and premium features like a built-in flashlight and a speaker for calls.
Think of it this way: The T-Rex 3 is a great value, while the T-Rex 3 Pro is a premium upgrade for those who need more from their gear, giving you a sense of indulgence and luxury in your outdoor adventures.
Build & Design: Same Beast, More Muscle
The T-Rex 3 is no pushover. It boasts military-grade durability and a bold, chunky design.
It can withstand most outdoor abuse, ensuring your peace of mind in any adventure.
But the T-Rex 3 Pro levels up in a few key ways:
Titanium vs Plastic/Steel
The Pro swaps out the plastic/steel frame for Grade 5 titanium. Stronger, lighter, and definitely feels more premium on your wrist, giving you a touch of luxury in your outdoor escapades.
Sapphire Glass vs Gorilla Glass: The Pro model features sapphire glass protection, which is significantly harder to scratch than the Gorilla Glass on the standard T-Rex 3.
More Size Options
Pro comes in 44mm and 48mm, so smaller wrists aren’t left out. The regular T-Rex 3 only has one size: big.
👉 In short, both are rugged, but the Pro is like the “armoured edition.”
Screen Brightness: A Clear Win for Pro
Both watches have AMOLED displays, so colours look sharp and vibrant. But the Pro has one significant advantage: brightness.
- T-Rex 3: 2000 nits (still bright)
- T-Rex 3 Pro: 3000 nits (sunlight killer)
If you spend a lot of time outdoors, especially under direct sunlight, the Pro’s screen will make your life easier.
Innovative Features
Where the T-Rex 3 Pro Wins Here’s where Amazfit decided to sprinkle some “pro magic.”
These additional features are not just gimmicks; they add significant value to the Pro, making it a more versatile and comprehensive smartwatch.
Here’s where Amazfit decided to sprinkle some “pro magic,” introducing innovative features that will surely pique your interest.
- Flashlight on Wrist: Yes, the Pro has a built-in LED flashlight with white, red, and SOS modes. Super handy for camping or even finding your keys in the dark.
- Speaker & Mic: The Pro lets you take Bluetooth calls or chat with the Zepp Flow assistant without touching your phone. The T-Rex 3 can’t do that.
- Better Navigation: Both watches have offline maps. Still, the Pro can also search for points of interest and even includes ski maps for snow lovers.
The regular T-Rex 3 covers the basics well, but the Pro feels more like a “Premium watch” on your hand.
GPS & Outdoor Tracking
No real losers here. Both watches come with:
- Dual-band GPS
- Six satellite systems
- Offline maps with turn-by-turn navigation
The Pro adds a little polish with those extra navigation perks, but both are rock-solid for hikers, bikers, and trail runners.
Health Tracking: Pro Gets an Upgrade
Health tracking is a big part of any smartwatch. Both models track heart rate, SpO2, stress, and sleep and offer 180+ sports modes.
But the Pro brings in Amazfit’s new BioTracker 6.0 sensor. It’s more accurate and works better across different activities.
Plus, you get BioCharge energy tracking, which basically tells you how much gas you’ve got left in the tank—great for planning workouts or recovery days.
Battery Life: Still a Monster
Battery life is one of the main reasons people love the T-Rex series. And good news—both models keep that reputation intact.
- T-Rex 3: Up to 27 days on regular use, 180 hours with GPS
- T-Rex 3 Pro (48mm): Around 25 days, 116 hours with GPS
- T-Rex 3 Pro (44mm): Slightly less, but still strong
So yes, the Pro loses a little stamina, but nothing major. Both watches easily outlast most smartwatches.
T-Rex 3 Pro VS t-rEX 3 Price
- T-Rex 3: Around $280
- T-Rex 3 Pro: Around $400
That’s a big jump. Do you really need the Pro features, or is the standard T-Rex 3 enough?
Final Verdict: Which One’s for You?
Here’s the short version:
- Go with T-Rex 3 if… You’re looking for a rugged, smartwatch with great GPS, killer battery life, and all the core health tracking—without overspending.
- Go with T-Rex 3 Pro if… You love premium materials, want brighter displays, extra navigation tools, or like having handy add-ons like a flashlight, speaker, and better health tracking.
Both are excellent watches. The T-Rex 3 offers 80% of the Pro’s features at a lower price.
Still, for serious adventurers or those who appreciate finer details, the Pro is worth the extra cost.
