Six Features I Already Love About the Amazfit T-Rex Ultra 2 Smartwatch.

The Amazfit T-Rex Ultra 2 is now available—a larger, flashier, more rugged, and significantly more expensive outdoor watch. At $549 , it’s Amazfit’s most expensive smartwatch ever, a rugged multisport device clearly aimed at adventure enthusiasts. While my detailed review isn’t complete yet (testing was hampered by a snowstorm), several features have already impressed me greatly.

The Ultra 2 has a really long battery life.

The watch’s main feature right now is its battery life. Amazfit claims up to 30 days of battery life in smartwatch mode—about 25% longer than the previous model—and up to 50 hours of GPS tracking. So far, battery drain has been impressively slow, even during my cold-weather workouts (where lithium batteries typically perform poorly).

If you spend long periods of time away from civilization, or simply hate carrying a charger everywhere, this improvement alone may justify the significant increase in size and price of the Ultra 2.

Ultra 2 features precise navigation that’s ready for offline use.

The most anticipated daily improvement is new pre-installed offline maps and overall more reliable map performance. For the first time in the T-Rex line, you can download full-color world maps directly from the Zepp app , then use them on your wrist without needing a phone or cellular connection.

Here are the highlights that I noticed personally—and that were confirmed by other users online:

• Map data is great for distinguishing between trails and roads.

• The offline route planning feature now supports routes up to 100 km long.

• GPS accuracy remains consistently high with the support of six satellite systems.

• Faster route reconfiguration and improved elevation profiles.

• The Points of Interest (POI) search is fantastic, showing all sorts of bodies of water, shelters, hiking trailheads, and emergency response locations nearby.

This has already proven useful in practice. When heavy snowfall blocked my usual running route, I switched to real-time navigation, quickly navigated the map, and found the nearest green space. It felt intuitive and fun. During a casual urban run, it was a pleasant reminder that navigation isn’t just about surviving harsh conditions.

Note: Route creation in the Zepp app could be improved. You can’t adjust the route by dragging the cursor between points, so you need to carefully plot it. However, the implementation on the watch is excellent, and features like “Explore Nearby” work well in open spaces (and my New York apartment is definitely not open).

With this watch, you can add voice memos to your workouts.

Press and hold the lower left button during a workout, and you can record a short voice memo with automatic geotagging. A thought popped into your head that you don’t want to lose? Want to remember a detail of your route? “Don’t take that icy turn again?” The ability to record during a workout is a significant improvement and a very welcome addition that has immediately become part of my training routine.

For strength training, this also provides a much more intuitive way to track metrics like reps and weight without interrupting your workout. Once synced with the Zepp app, your notes are timestamped, transcribed, and saved with playback capabilities, making it easy to see exactly what you recorded and when.

The Ultra 2’s hardware is big, bright, and reliable.

Amazfit clearly aims for the Ultra 2 to rival the most rugged adventure watches on the market. The specifications reflect these ambitions:

• 1.5-inch AMOLED touchscreen

• Scratch-resistant sapphire crystal

• Bezel and case back made of grade 5 titanium

• Water resistance 10 ATM

• Dual diver certification

• 64GB of storage for maps, music, and activity data.

The new 3000-nit display is a monster, claiming to be three times brighter than the original Ultra. The image is crisp and easily visible even in bright sunlight (or, as I recently discovered, even in sunlight reflecting off snow).

The Ultra 2 flashlight has also received an update.

Last year, Amazfit replaced the red LED with a greener one. The flashlight is now located at the 12 o’clock position, and the controls are intuitive:

• Press and hold the Up button to turn on the device. • Tap the icon on the screen to switch modes. • Press the Up or Down button five times to change the brightness or activate green mode.

It’s a small detail, but it reinforces the idea that this is a watch primarily for outdoor use. I haven’t yet tested it on night runs, hikes, or emergency situations, but I can say it works great in a dark city apartment!

The Ultra 2 trainer has workout modes for just about anything.

Amazfit has included more than 180 sports modes in the Ultra 2 model, including highly specialized ones such as spearfishing, freediving, parkour, and snorkeling.

In this same sports modes section, the watch also includes:

• Pace for runners adjusted for terrain

• Improved lift segmentation

• Built-in speaker and microphone for Bluetooth calls and audio notifications.

• Seamlessly integrates with the Zepp app for insights on fitness, recovery, sleep, and nutrition.

First impressions are promising. Even if some recently announced software features haven’t yet been fully refined, Amazfit’s ambitions are clear.

Final (preliminary) impressions of Ultra 2

There’s still a lot of testing to do before I can answer the main question: is the Amazfit T-Rex Ultra worth $2,549—especially given Garmin’s already dominant position in the outdoor device market? However, there are already clear and significant improvements that impress me: full-fledged offline mapping, the best battery life ever for an Amazfit watch, a surprisingly convenient voice memo tool, and hardware that seems built for the apocalypse.
