Amazfit T-Rex 3 Pro Smartwatch 44mm

The 44mm version typically lasts up to 17 days with regular use, which is a bit shorter than the 25 days seen on the larger 48mm model. If you use the Always-On Display and heavy GPS tracking, expect to charge it every 8 to 10 days.

It is exceptionally bright, hitting a peak of 3000 nits on its AMOLED display. This makes it one of the easiest screens to read under direct, harsh sunlight, though some users find the auto-brightness a bit too conservative indoors.

Yes, it comes with a built-in speaker and microphone, so you can handle Bluetooth calls directly from your wrist. It also supports the Zepp Flow voice assistant, allowing you to reply to messages or set alarms hands-free.

It definitely is! The watch is certified for recreational diving up to 45 meters and has a 10 ATM water resistance rating. It even includes a dedicated depth gauge and water temperature sensor that activate automatically when you dive.

Yes, it features enhanced offline contour maps that you can download directly to the watch. This is a huge plus for hikers in the Himalayas or Western Ghats, as it allows for precise navigation without needing a mobile network.

It uses multiband/dual-frequency GPS, which provides high accuracy even in dense city areas or deep forests. While it's generally spot-on, some users have reported a slight delay in re-establishing a signal if you lose it inside a building or elevator.

It uses the BioTracker 6.0 sensor to monitor sleep stages, naps, and even breathing quality. It also gives you a BioCharge energy score, which acts like a recovery guide to tell you if you're ready for a heavy workout or need rest.

Absolutely, it’s built to MIL-STD-810G military standards and features a Grade 5 titanium bezel. It can handle extreme shocks and temperatures as low as –30°C, making it one of the toughest smartwatches available in India.
