Garmin appears to be on the cusp of unveiling its premium outdoor smartwatch, following the emergence of an unnamed wearable in recently disclosed U.S. certification documents.
Designated with the model number A05216, this device has been documented with the US Federal Communications Commission (FCC), igniting speculation that Garmin is poised to broaden its selection of endurance-centric smartwatches.
While Garmin has refrained from disclosing specifics about the device in the certification filing, observations in the Garmin Connect app hinting at an Enduro 4 have led many industry experts to surmise that this certification may pertain to the much-anticipated successor to the Enduro 3.
The regulatory documentation, while not revealing the smartwatch’s design, does shed light on its technical prowess. As per the filing, the device boasts compatibility with Bluetooth 5.0 Low Energy, operates on dual-band Wi-Fi across both 2.4GHz and 5GHz networks, and incorporates GPS functionality.
Furthermore, the certification indicates that this smartwatch is engineered to thrive in demanding outdoor conditions. It can function effectively in extreme temperatures, ranging from -20°C to 50°C, making it suitable for diverse activities, including trail running, hiking, and endurance challenges across various climates.

Further technical specifications reveal that the device will utilize Garmin’s proprietary charging interface. The documentation specifies standard charging capabilities between 10V and 24V DC with a maximum current of 2A, while separate USB charging is available at 5V and 3A.
Moreover, the filing notes the inclusion of an innovative inverted-F GPS antenna, which could significantly enhance satellite reception and locational precision during outdoor endeavors.
Although the certification falls short of definitively confirming the product’s identity, the timing heightens anticipation of a replacement for the Enduro 3. Garmin’s current endurance smartwatch has been on the market for over two years, rendering it one of the more antiquated premium models within the company’s extensive portfolio.
An additional clue emerges from the FCC’s request for confidentiality, which prohibits the disclosure of product images until mid-November. Manufacturers generally maintain confidentiality when a product is expected to debut before the public release of regulatory documents, suggesting an announcement may be imminent in the months to come.
Should the smartwatch materialize as the Enduro 4, expectations suggest it will uphold Garmin’s commitment to exceptional battery longevity and sophisticated outdoor fitness tracking. Speculation further points to innovative features, including advanced satellite communication or hardware advancements originating from Garmin’s future Fenix smartwatch platform.
As of now, Garmin remains reticent regarding its strategic intentions. Nonetheless, the recent certification stands as one of the most compelling indicators yet that the company’s next flagship endurance smartwatch may soon be ready for revelation.
