New Polar smartwatch breaks cover via FCC as Polar Street X
A new Polar smartwatch is on the horizon. A recent regulatory filing confirms that a device called the Polar Street X is now listed with the FCC under ID INW6J, offering a closer look at what could be the next entry in the company’s urban fitness range.
Polar Street X surfaces in FCC paperwork
We just spotted the filing, but it was actually released on January 23rd. The documents point to a smartwatch currently being developed by the company.
The device goes by the internal name Polar 6J and appears to sit on a new hardware platform titled “Polar 6J Elabel.” This platform enables digital regulatory labeling, meaning users can access certifications directly through the watch interface under Settings > About > Certificates. That includes the FCC ID and other compliance data.
The watch itself is classified as a close-body wearable. That suggests it’s designed for continuous wrist contact, with testing assuming a usage distance of under 5 mm. Its wireless communications are handled entirely via Bluetooth Low Energy (BLE), supporting both 1 Mbps and 2 Mbps data rates over the standard 2402–2480 MHz band. Maximum output power is capped at 3.60 milliwatts.
At the core of its wireless setup is a custom-built antenna. Labeled as model 115326-3, this antenna is specific to Polar’s own 6J architecture. Its maximum gain sits at -3.3 dBi at 2440 MHz, pointing to a design more focused on efficient short-range connection rather than long-range broadcast strength. That fits with typical smartwatch use where pairing with a nearby phone is the norm.
Retail packaging
More interesting than the technical details is the product packaging shown in the documentation. It confirms a black color variant (referred to as Night Black) with a silicone strap and clearly references the product name “Polar Street X” on both the retail box and the digital label screen. The package also confirms that this is a size S-L unit, which could imply multiple sizes may be offered.
The FCC documents cover conducted and radiated testing, including power spectral density, bandwidth and spurious emissions. This is standard for Bluetooth wearables but also confirms that the device is well into its compliance checks.
What’s not mentioned is any GPS, Wi-Fi, cellular or multi-frequency functionality. This points toward a more lightweight urban-focused wearable rather than a full multisport or outdoors unit like the Vantage or Grit series. That also lines up with the “Street X” branding, which hints at something more lifestyle-oriented.
Adding further confirmation to this are a couple of retailer mentions. No pics or specs listed but a price of around 220 euros is mentioned.
We will learn more once Polar officially unveils the Street X. The confidentiality clause on all the FCC paperwork runs out in late March, so a launch is likely before then.
