Exclusive: Amazfit T-Rex Ultra 2 shows up in Zepp Health app code
A new watch name has appeared in the latest version of the Zepp Health app. Strings referencing the Amazfit T-Rex Ultra 2 are present in version 9.16.2, but absent from earlier builds, suggesting a follow-up to last year’s premium outdoor model could be in the works.
References to T-Rex Ultra 2 show up in app code
We dug into the APKM for Zepp 9.16.2 and spotted a few references to T-Rex Ultra 2 inside the code. The exact string “Amazfit T-Rex Ultra 2” now lives in the string pool section, where model identifiers are typically declared for pairing and UI purposes.
This wasn’t just a label fragment. The full name appears cleanly and is repeated across several assets. A regex pattern match (T-Rex Ultra 2-\w{4}) in the DEX file hints at serial variants or internal model suffixes, similar to those used in previous releases.
All of this is new in version 9.16.2. None of these strings are present in 9.15.2, which strongly suggests they were introduced intentionally.
Original Ultra model launched in 2023
The first Amazfit T-Rex Ultra landed in March 2023, positioned as a flagship rugged watch in the T-Rex line. It wasn’t a full generation leap, more than an interim improvement over the T-Rex 2 at the time.
A few things set it apart such as a stainless steel bezel and backplate, giving it a more rugged feel than the plastic shell of the T-Rex 2. It also added Wi-Fi, which means you can download maps and music straight to the watch instead of going through your phone.
Beyond that the device launched with some other extras such as diving features, a few more sports modes and a more up to date version of the operating system. Battery life and sensors stayed the same.
If the Ultra 2 is coming, it will need to offer solid improvements on the T-Rex 3 line. We might see improvements in battery life, more advanced sensors, better durability and build. That’s speculation for now, but the inclusion of Ultra 2 references in both app resource and code files is usually a sign something is on the roadmap.
Could we see it at MWC 2026?
The timing fits. Zepp Health has used the MWC window before for announcements. A March release would mirror the original Ultra launch schedule. With multiple versions of T-Rex 3 already out and the Balance line handling lifestyle and wellness, there’s room again for a more rugged, high-end model.
We’ll be watching closely for certifications, FCC filings or teasers in the coming weeks. But based on the latest Zepp app update, a soonish launch of the Amazfit T-Rex Ultra 2 is looking quite possible. If it launches, no doubt, it will be an excellent alternative to the more expensive Garmin.
