Amazfit T-Rex 3 Pro Review: A $400 Garmin Alternative with Built-in LED Flashlight

Why the Built-in LED Flashlight Matters

If you’ve ever used a Garmin Fenix or Epix with a flashlight, you know it’s a game-changing feature.

The T-Rex 3 Pro flashlight is no gimmick — it offers:

• Three brightness levels (low to high)
• Red light mode (for night vision & wildlife safety)
• Custom safety flashes (great for runners and cyclists)

Whether you’re walking your dog at night, setting up camp, or caught in a dark trail, having light on your wrist beats fumbling for a phone.

Garmin no longer holds the flashlight monopoly — Amazfit just undercut them at half the price.

Ready for Outdoor Fun

The T-Rex 3 Pro isn’t your typical “flashlight watch.” This beast is built for the outdoors.

Its titanium body and sapphire glass face shrug off scratches and rough knocks like it’s no big deal. Even in brutal cold—think -30°C (-22°F)—it keeps ticking.

On top of that, it’s been tested to military-grade standards for shock, heat, and water resistance.

In short, this isn’t the kind of watch you wear while lounging on the couch. It’s made for people who ski down icy slopes, cast fishing lines before sunrise, crush trail runs, or climb mountains just for the view at the top.

Battery Life: Long Enough for Real Adventures

Battery life is one of the best parts of adventure watches. Luckily, Amazfit nailed it here:

• 19 days of typical everyday use
• 29 hours in precision GPS mode
• Ultra-battery saving options for extended expeditions

Yes, it’s bulky (especially the 48mm model), but the massive battery justifies the space on your wrist.

Navigation and Maps

For years, Garmin had a lock on advanced navigation. Amazfit is finally stepping up:

• Downloadable maps for hiking, running, and outdoor trails
• Turn-by-turn navigation for supported activities
• Ski maps with slope colours and lift details

For skiers and mountaineers, having slope info and offline navigation at $400 is a serious breakthrough.

Sports Modes: Beyond the Basics

Unlike most smartwatches that cover “running, cycling, swimming,” the T-Rex 3 Pro goes big with 180+ sports modes, including:

• Running, cycling, triathlon
• Skiing and snowboarding
• Fishing (with cast tracking + fish logging)
• Dog walking (tracks stop-and-go pace changes)
• Strength training + gym workouts

This variety makes it one of the most well-rounded multisport watches outside Garmin’s ecosystem.

Smartwatch Features: Hits and Misses

The Amazfit T-Rex 3 Pro tries to give you the best of both worlds — tough outdoor gear mixed with everyday smartwatch features. Here’s what it does well:

The Amazfit T-Rex 3 Pro comes equipped with NFC, enabling contactless payments through Zepp Pay.

However, its availability can vary depending on your region. Some versions include the necessary hardware, but Zepp Pay might be disabled in areas where the service isn’t officially supported — so functionality ultimately depends on local compatibility.

✅ You can answer calls and use your voice assistant thanks to the built-in mic and speaker.

✅ Notifications land right on your wrist through the Zepp app, so you don’t have to pull out your phone every time.

But there are a few gaps:

❌ No Spotify, Apple Music, or other streaming services.

❌ The app store isn’t as rich as what you’ll find on Garmin or Apple.

If you need contactless payments or offline music, Garmin is preferable. But if you want a rugged outdoor watch for calls and notifications, Amazfit fits the bill.

So, the trade-off: for payments or offline Spotify, choose Garmin. For rugged connectivity outdoors, choose Amazfit.

Sleep and Health Tracking

One downside: the T-Rex 3 Pro is too bulky for comfortable sleep tracking. Amazfit solves this with its Helio ecosystem:

• Use the Helio Strap or Helio Ring at night
• Syncs sleep + recovery data with the Zepp app
• Gives you 24/7 tracking without wearing a massive watch in bed

This “two-device approach” is innovative — and unique in the rugged watch space.

Design and Availability

The Amazfit T-Rex 3 Pro comes in:

• 48mm: Tactical Black, Black Gold
• 44mm: Gold/Grey, Black Gold (better for smaller wrists)

Meanwhile, the regular T-Rex 3 remains available at a lower price for those who don’t need the premium build or flashlight.

Final Verdict: Is the Amazfit T-Rex 3 Pro Worth It?

If you need music, payments, or advanced app support, Garmin still holds the crown.

But if you’re an adventurer focused on safety, battery, and value, the T-Rex 3 Pro might be the smartwatch to beat this year.
