The T-Rex Ultra 2, the newest GPS smartwatch from Zepp Health's flagship wearable brand Amazfit, is designed for use on expeditions and in harsh conditions.

The watch has biotracking and activity technology that measures blood oxygen, heart rate, breathing rate, sleep quality, and stress levels, reports MobiHealthNews.

The wearer's breathing patterns, sleep stages, and quality of sleep are all examined by the sleep-tracking algorithm.

The Zepp App, which displays trends and charts of health parameters and enables users to compare activity over time, allows users to view the data they have collected.

The watch is compatible with both Apple and Android phones, and in addition to health-related apps, users can send and receive texts and make phone calls. The watch features GPS, a built-in backlight, a battery life of up to 30 days, and water resistance for up to 10 minutes at a depth of 100 meters (328 feet).

By utilizing Low Temperature Mode, which maintains the watch's fundamental functions responsive even at temperatures as low as -22°F or -30°C, it may also continue to function in extremely cold conditions.

The T-Rex Ultra 2 will go on sale on February 19 and retail for $549.99.

"With the T-Rex Ultra 2, we focused on building a watch for people who rely on navigation, endurance and on-watch decision-making in demanding environments," Scott Shepley, head of global marketing at Amazfit, said in a statement.

"It's designed for long, complex routes where preparation and reliability matter, and it complements the T-Rex 3 Pro within the T-Rex family by serving a more expedition-focused use case."

The Larger Trend

Zepp OS, a wristwatch operating system based on OpenAI's ChatGPT-4o paradigm, was introduced by Zepp Health in 2024. Zepp Flow, a voice assistant that enables the wearer to operate the gadget with speech commands without the need for particular keywords or physical contact, was debuted with the integration.

Amazfit and the women's health portal Wild announced a collaboration that same year.AI helps women "track, train, fuel and recover" according to their life stage and cycle, from menstruation to menopause, by using physiological and hormonal data.

Through the collaboration, the Wild.AI mini-app, a wellness tool that tracks hormones and cycles, was integrated into the Amazfit Active 2 wearable. Customized training, food, readiness scores, and performance recommendations based on a woman's physiology might be provided to watch wearers.

Zepp Health, the parent company of Amazfit, purchased Wild.AI's core technology and assets last year, including several of its top team members and proprietary technology.
