In a year marked by aggressive product refreshes from Zepp Health, a final piece of the Amazfit puzzle has just appeared. A mysterious new smartwatch, identified by the model number A2557, has been logged in a regulatory database.
Based on Zepp Health’s established product cadence and recent corporate promises, this isn’t just another Bip or Active variant. All signs point to the long-awaited update to the flagship Performance line.
If you’ve been holding out for a successor to the mighty Falcon or the runner-focused Cheetah, the A2557 is the leak you need to watch.
The Clue: A Mysterious SIRIM Filing
The entire speculation hinges on a SIRIM (Malaysia’s regulatory body) registration for a device bearing the internal model code A2557 on November 25th. While these filings reveal almost no specifications, the timing and model-number structure tell a compelling story.
- The Numbering Trend: Zepp Health typically uses consecutive model numbers within a product generation. The immediate predecessor, A2549, is widely believed to be the recently released 44mm variant of the rugged T-Rex 3 Pro. Since the A2557 is not tied to any other known variant, it signals an entirely new product.
- The Timing Window: November 25th filing lands at the tail end of the company’s stated product refresh cycle, making it a likely candidate for a final Q4 2025 launch or an early Q1 2026 debut.
The Logic: Why These Points Lead to the Performance Line
Zepp Health’s current portfolio is structured around four primary categories, and 2025 has already seen three of them updated:
| Amazfit Tier | Key Focus | 2025 Status (Confirmed Updates) |
| Essential | Value & Basics | Bip 6 |
| Lifestyle | Style, Health, & AI | Active 2, Balance 2 |
| Adventure | Ruggedness & Outdoors | T-Rex 3 Pro |
| Performance | Pro-Grade Sports & Metrics | STILL PENDING (Falcon, Cheetah lines) |
Corporate Strategy Confirms the Gap
During their Q1 and Q3 2025 earnings calls, Zepp Health executives explicitly stated their aim to “refresh all core product lines by year-end.”
With the Bip, Active, and T-Rex lines already updated, the only major segment left is the high-end Performance tier, home to the premium Amazfit Falcon and the severe running watch, the Amazfit Cheetah.
The A2557 is the logical “missing piece” to fulfill this strategic promise.
What Could the A2557 Be? (Our Best Guess)
The high-end focus of the Performance line gives us a strong indication of the features we can expect from the A2557:
1. Amazfit Falcon 2: The Premium Multi-Sport Flagship
Given that A2557 is likely the final launch of the cycle, it could be the ultimate flagship. The Falcon line is known for its premium build (often titanium and sapphire glass) and pro-level features.
- Expected Upgrades: Next-generation BioTracker sensor, Zepp OS 5.0 with enhanced AI coaching (Zepp Coach™), more on-board storage, and potentially even more advanced recovery metrics integrated with the Helio Strap ecosystem.
2. Amazfit Cheetah 3: The Runner’s Companion
Alternatively, the A2557 could be the next iteration of the Cheetah, explicitly designed for serious runners and triathletes.
- Expected Upgrades: More accurate Dual-Band GPS (perhaps adding even more satellite systems), even lighter materials, and advanced offline mapping and route-guidance features tailored for marathoners and trail runners.
When Will We Get Concrete Details?
While the SIRIM filing confirms the device exists and is moving through the approval process, we need a filing from the FCC (Federal Communications Commission) or a similar body in the US or Europe to obtain technical details.
FCC documents typically include:
- Connectivity Specs (e.g., Wi-Fi, Bluetooth standards)
- Battery Capacity
- Sometimes, a basic schematic or photo
Keep an eye out for these filings in the coming weeks. The clock is ticking, and Zepp Health is running out of 2025 to keep its promise.
Final Thought
The A2557 leak is highly exciting because it addresses the single remaining, high-value gap in Amazfit’s 2025 lineup.
Whether it’s a new Falcon, a new Cheetah, or a completely new pro-series watch, the wearable market is about to get a powerful new player just in time for the new year.
