The wearable market is buzzing with news of a surprise entry from Polar. While the company recently expanded its rugged lineup with the Grit X2, fresh regulatory filings suggest that a brand-new model, dubbed the “Street X,” is already waiting in the wings. This discovery, surfacing via the Federal Communications Commission (FCC), offers a rare and detailed early look at what Polar has planned next.
Detailed FCC Filings Reveal the “Street X”

While most FCC filings are notoriously vague, the documentation for this new device—identified by the model number “6J”—is surprisingly comprehensive. The “Street X” moniker suggests a shift in branding for Polar, potentially targeting a more urban or lifestyle-oriented demographic compared to their traditional outdoor and endurance-focused “Grit” and “Vantage” series.
The presence of the device in US regulatory databases is a strong indicator that Polar is planning a worldwide launch, maintaining its competitive stance against rivals like Garmin and Apple.
Design Cues and Aesthetic Choices
Initial imagery from the leak indicates that the Street X draws significant design inspiration from the Vantage M, which saw a refresh in late 2024. The aesthetic appears sleek yet functional, balancing Polar’s performance heritage with a modern silhouette.
According to the leaked details, the smartwatch will feature:
-
Color Profile: A primary “Night Black” finish.
-
Materials: A durable silicone watch band designed for high-intensity activity and daily wear.
-
Fitment: A “one-size-fits-all” approach, with packaging mockups indicating that the strap will accommodate sizes ranging from Small to Large.
Market Positioning and Expected Arrival
The Street X follows closely on the heels of the Grit X2, which landed in the US market in October 2024. By introducing the Street X so soon after, Polar seems to be diversifying its portfolio to capture users who want high-end tracking capabilities without the bulky “rugged” aesthetic of the Grit series.
While the FCC documents provide a clear picture of the device’s physical attributes, Polar has yet to confirm official technical specifications, retail pricing, or a specific launch date. However, given the advanced state of the regulatory filings and the inclusion of retail packaging mockups, an official announcement is likely just around the corner.
