Yesterday, I broke the news after spotting a new Amazfit smartwatch—model number A2570—across multiple Asian certification databases, including Malaysia’s SIRIM, which officially confirmed the name: Amazfit T-Rex Dual Solar.
Today, while digging through the FCC database, I found the same device. The new filing gives us our very first look at the official technical schematics and antenna design for Amazfit’s upcoming solar-powered watch.
FCC Listing Details
The filing officially registers model A2570 under Anhui Huami Information Technology Co., Ltd. (Zepp Health).
Here are the primary regulatory details:
-
FCC ID: 2AC8UA2570
-
Applicant: Anhui Huami Information Technology Co., Ltd.
-
Equipment Class: Smart Watch
-
Test Firm: Shenzhen CTA Testing Technology Co., Ltd.
-
Testing Documentation: Antenna Test Report 9549864
Technical Diagrams Reveal Design and Dimensions

The antenna report includes detailed technical diagrams of the inner frame structure, giving us direct insight into the watch’s physical setup and button layout.
1. Classic Rugged Bezel & Circular Shape
The diagrams confirm a classic circular, heavy-duty shape that matches the rugged aesthetic the T-Rex line is known for. The inner metal frame and antenna ring measure 49.97 mm x 51.67 mm, indicating a full case size around 50 mm.
2. Physical Four-Button Layout
The schematic labels four distinct physical control points engraved around the perimeter:
-
UP (Top Left)
-
DOWN (Bottom Left)
-
SEL (Select / Top Right)
-
BACK (Bottom Right)
This four-button layout provides a reliable interface for navigating menus, tracking sports, and recording outdoor split times without relying entirely on a touchscreen in wet or extreme conditions.
3. Integrated Ring Antenna Design
The documentation highlights an integrated ring antenna running around the outer perimeter of the watch face casing. This circular arrangement maximizes signal reception for multi-band satellite location services while keeping the internal space clear for components and a large capacity battery.
What This Means for Launch
With certifications now cleared across Malaysia, Indonesia, South Korea, and now the US FCC, the Amazfit T-Rex Dual Solar has passed major global regulatory approvals.
With all the paperwork falling into place, a formal announcement from Zepp Health looks to be right around the corner. Stay tuned as more details develop.
