Amazfit T-Rex Dual Solar 2026: The First Solar-AMOLED Smartwatch Is Coming — Should You Wait?
The Amazfit T-Rex Dual Solar has quietly cleared regulatory approval in five countries, and the name alone tells a story no other smartwatch can: a combination of AMOLED display and solar charging that has never shipped on a production wearable. With an IFA 2026 reveal expected in less than three weeks, here's what the filings reveal and whether outdoor watch buyers should wait.
Status
FCC approved (Aug 12). Five regulatory bodies cleared. No official launch date.
Expected Launch
IFA 2026, Berlin, September 5–9. Retail availability likely September–October.
Expected Price
$300–$450 based on T-Rex lineup history. Significantly cheaper than Garmin solar watches.
Why "Dual Solar" Is a Big Deal
Solar charging on smartwatches isn't new — Garmin has offered it since the Fenix 6 Solar in 2019. But every solar-equipped smartwatch until now has used MIP (Memory-in-Pixel) displays, which are partially transparent and allow sunlight to pass through to solar cells underneath. AMOLED screens are opaque, which is why no manufacturer has successfully combined solar charging with the vibrant, high-contrast AMOLED displays that buyers prefer.
The T-Rex Dual Solar appears to solve this in one of two ways: a secondary MIP solar panel that sits around or behind the AMOLED display, or dual-zone solar cells distributed across the watch face bezel and case. Either approach would let Amazfit offer the best of both worlds — a bright, colorful display for daily use and solar-extended battery life for multi-day outdoor adventures.
What Do the FCC Filings Reveal?
The FCC filing under model A2570 confirms:
- Wi-Fi and Bluetooth connectivity — standard for GPS smartwatches
- Dual-frequency GNSS — likely for improved GPS accuracy in challenging environments (urban canyons, forests)
- Battery capacity: Not disclosed in available filings, but the "Dual Solar" name implies extended runtime is the headline feature
The Malaysian telecom registration explicitly names the device as "Amazfit T-Rex Dual Solar," confirming this is not just a codename. FCC approval in the US is the last major regulatory hurdle before a US launch.
How Does the T-Rex Dual Solar Compare to What's Available?
The outdoor smartwatch market is about to get crowded:
- Garmin Fenix 9 ($999, August 25): The premium outdoor king with tri-band GNSS, MIP Solar option, and Garmin's deep training ecosystem. Three times the expected T-Rex Dual Solar price
- Apple Watch Ultra 3 ($640): Cellular, 36-hour battery, iPhone-only. No solar charging
- Galaxy Watch Ultra 2 ($699): Android's premium option with 72-hour battery and Snapdragon Wear Elite. No solar
- Garmin Venu 4 ($540): AMOLED + Garmin ecosystem, but no solar charging
If Amazfit prices the T-Rex Dual Solar at $300–$400, it would be the most affordable outdoor watch with both AMOLED and solar — a combination currently available at no price point.
What About Amazfit's Track Record?
Zepp Health (Amazfit's parent company) has a solid track record with the T-Rex line. The T-Rex Ultra delivered military-grade durability and dual-band GPS at $300 — roughly one-third the price of comparable Garmin models. Zepp also demonstrated engineering ambition with the Helio Ring 2 patent revealing ECG and body composition from a single ring. The company is clearly willing to push boundaries.
The risk? Patents and FCC filings don't guarantee the final product will match the ambition. The "Dual Solar" label could describe a simpler implementation than the dual-display hypothesis — perhaps just solar cells on the watch bezel without a secondary screen. We'll know for sure at IFA.
Should You Wait for the Amazfit T-Rex Dual Solar?
Wait if: You want an affordable outdoor watch with solar charging and AMOLED, and you're not locked into Garmin's ecosystem. IFA is less than three weeks away — the wait costs nothing.
Buy now if: You need a watch for an upcoming trip or event. The Garmin Venu 4 at $540 is the best AMOLED outdoor watch available today, and the Apple Watch Ultra 3 at $640 is unbeatable for iPhone users. If you're on a budget, the Pixel Watch 5 at $399 goes on sale August 20 with strong launch deals.

Common questions about the upcoming T-Rex Dual Solar
Quick answers on what the FCC filings reveal, pricing expectations, and whether to wait.
What is the Amazfit T-Rex Dual Solar?
The Amazfit T-Rex Dual Solar (model A2570) is an upcoming outdoor smartwatch from Zepp Health that has cleared five international regulators including the FCC. The 'Dual Solar' name suggests a first-of-its-kind architecture combining an AMOLED display with solar charging technology — something no production smartwatch has shipped before.
When will the Amazfit T-Rex Dual Solar launch?
Industry insiders expect an unveiling at IFA 2026 in Berlin (September 5–9). The watch has cleared regulatory approval in the US, Indonesia, South Korea, Malaysia, and the Eurasian Economic Union — a pattern that typically precedes a launch by 4–8 weeks.
How much will the Amazfit T-Rex Dual Solar cost?
No price has leaked yet. The current T-Rex Ultra retails around $300, significantly cheaper than comparable Garmin models ($540–$999). Expect the Dual Solar to price between $300 and $450 based on Amazfit's historical positioning.
How does solar charging work on an AMOLED smartwatch?
No one has shipped this combination before. Garmin uses solar on MIP (Memory-in-Pixel) displays because MIP panels are partially transparent. AMOLED screens block sunlight. The T-Rex Dual Solar likely uses a secondary solar panel around or behind the main display, or dual-zone solar cells on the watch face bezel and case sides.
Should I wait for the Amazfit T-Rex Dual Solar or buy a Garmin Fenix 9?
If ecosystem matters, the Garmin Fenix 9 (launching August 25 at $999) offers Garmin's deep training ecosystem. If price matters, the T-Rex Dual Solar will likely cost less than half the Fenix 9. Both are expected within weeks, so waiting for both announcements before deciding costs you nothing.
