Additionally, it has passed 15 military-grade tests, making it a reliable choice for outdoor adventurers. The adjustable lugs ensure maximum comfort, and the responsive touchscreen and four convenient buttons make it easy to navigate.

The Apple Watch Ultra on the other hand also boasts a durable design with a 49mm corrosion-resistant titanium case and 100m water resistance. The Digital Crown and buttons are more accessible, making it easier to control, and the customizable Action button provides physical control over a variety of functions.

The screen is easy to read, even in bright sunlight, and the adjustable brightness settings allow you to customize it to your liking.

Whereas, the Apple Watch Ultra’s 1.92-inch Always-On Retina display is even larger and has 2000 nits brightness, making it easy to see in any lighting conditions. It offers more room for adding complications to customize your watch face and features an LTPO display for improved battery life.

GPS and Navigation

As for GPS and Navigation, the Amazfit T-Rex Ultra utilizes both L1 and L5 signals for incredibly precise dual-band GPS positioning, and supports six satellite systems for greater global coverage. Import a route file to the watch along with a corresponding Offline Map, and navigate with professional-level environmental understanding. The smartwatch also supports indoor and outdoor freediving to a depth of up to 30 meters and can resist the equivalent of up to 100 meters of water pressure, making it perfect for all your swimming, surfing, and kitesurfing activities.

The Apple Watch Ultra features precision dual-frequency GPS for accuracy, distance, route, and pace calculations. The redesigned Compass app delivers all-new views and functionality, and the Trail Loop band is designed especially for runners. The Backtrack feature uses GPS to map where you’ve been, so you can retrace your steps.

For water sports enthusiasts, the Oceanic+ app puts a dive computer on your wrist, and the Ocean Band is light and flexible, with a titanium buckle and adjustable loop for a secure fit even during high-speed water sports. The Sonic Salvation feature sets the Apple Watch Ultra apart from others as it offers an 86-decibel siren, which can be activated by holding down the action button. This unique feature can come in handy if you ever find yourself in a situation where you need to attract attention, whether you’re lost, injured, or in need of help. The siren is capable of being heard from up to 600 feet or 180 meters away, making it a reliable and effective tool in emergency situations.

Regarding the battery life, the Amazfit T-Rex Ultra boasts an impressive 20-day battery life, which is among the longest of any smartwatch on the market. It also features a new Endurance GPS battery mode for those who love to lose themselves in nature for long periods of time, plus a new Automatic GPS battery mode that intelligently adjusts GPS settings based on signal strength, to help conserve power.

The Apple Watch Ultra offers up to 36 hours of battery life, which is still quite good. It also features the freedom of cellular, so you can call and text without your iPhone and stream your favorite music and podcasts. However, the battery life is not as long as the Amazfit T-Rex Ultra.

Final Verdict

In conclusion, both the Amazfit T-Rex Ultra and the Apple Watch Ultra are great options for those seeking a durable and rugged smartwatch with a range of features to suit outdoor enthusiasts and endurance athletes. The Amazfit T-Rex Ultra offers an impressive battery life that Apple Watch Ultra lacks. Apart from that, the Apple Watch Ultra has so many advanced features that are missing in the Amazfit T-Rex Ultra. So, Amazfit needs to do a lot of work for their Ultra title.
