Amazfit T-Rex Dual Solar revealed in regulatory filings

Zepp Health appears to be getting ready to launch its first solar-powered watch, and we may finally have a name for it. Multiple regulatory filings identify a new A2570 smartwatch, with the Malaysian registration going one step further and naming it the Amazfit T-Rex Dual Solar.

Three registrations point to the same watch

The trail starts in Indonesia, where A2570 appears in the country’s official Sertifikasi Indonesia database. The listing identifies the device as an AMAZFIT smartwatch manufactured in China. Its certificate number is 125183/DJID/2026, with PT GLOBALTAMA SUKSES MAKMUR shown as the applicant.

South Korea’s RRA database also contains A2570. The registration lists Anhui Huami Information Technology Co., Ltd. as the applicant and gives it the verification code RC-hM6-A2570. Certification was granted on August 4, 2026, with China and Vietnam listed as countries of manufacture.

Then comes the Malaysian filing, which gives away considerably more.

SIRIM lists model A2570 together with the marketing name T-REX DUAL SOLAR. The type approval code is RDCX/40N/0726/S(26-4227), with an approval date of August 3, 2026. COMSAT MOBILE COMMUNICATION SDN BHD is listed as the certificate holder.

We also spotted Model A2570 in the Eurasian Economic Union registry. Which adds another regulatory appearance for the same device.

This fits what we found in the Zepp app

What makes this particularly interesting – in June, we found solar-related functionality inside the Zepp Health app. The code included SolarBatteryChargeRecord, solar intensity data and references to watch_face_input_power and case_back_input_power.

At the time there was no product name attached to any of it. The code simply suggested Zepp Health was preparing its software for hardware capable of reporting solar or light-based power input.

A few days later, an unidentified rugged watch appeared on Amazfit Spain’s official Instagram account. It had the chunky round shape and red bezel detail associated with the T-Rex family, but it did not resemble any model Zepp Health was selling.

The display also looked noticeably different from the glossy AMOLED screens used on recent T-Rex watches. We suggested at the time that it could be a low-power MIP display and possibly the solar watch hinted at in the Zepp app. The new T-Rex Dual Solar model now looks like it could be a likely candidate.

The “Dual Solar” name does suggest there is something more going on than simply adding a small solar ring around the display. It could refer to two separate solar collection areas, different types of photovoltaic elements, or some other dual-component charging arrangement.

Zepp Health is already starting from a strong position here. The Amazfit T-Rex Ultra 2 packs an 870 mAh battery and is rated for up to 30 days of typical use. Solar assistance on a watch designed around lower power consumption could push endurance much further.

A launch now looks much more plausible

There was already another clue that the T-Rex family had more to come this year.

During its 2026 earnings commentary, Zepp Health said it had additional T-Rex family products lined up for later in the year. We flagged those comments in June, before the solar app code and these regulatory filings appeared.

Regulatory approval does not tell us exactly when the watch will launch. Still, these multiple certifications suggest the hardware is well beyond the early prototype stage. IFA 2026 is around the corner. Don’t be surprised if the device makes its debut in early September.
