Premium 316L Stainless-Steel Construction

The Amazfit T-Rex Ultra is designed to withstand demanding outdoor conditions without sacrificing comfort or usability.

Key durability features include:

• 316L stainless-steel bezel, buttons, bridge and back panel

• Mud-resistant hardware design

• Four physical control buttons

• Responsive touchscreen

• Adjustable lugs for improved wrist comfort

This rugged construction makes it suitable for hiking, trekking, climbing, trail running, camping and demanding everyday use.

View maps, workout statistics, notifications and outdoor data clearly on the 1.39-inch HD AMOLED display.

Dual-Band GPS with Six Satellite Systems

The T-Rex Ultra uses dual-band positioning with L1 and L5 satellite signals for improved tracking in challenging environments.
