Polar Flow update hints at two new X series watches
Polar has pushed out Polar Flow version 7.35.0 and our APK teardown has revealed two unreleased devices hiding in plain sight. Alongside the already known INW6J identifier tied to Polar Street X there is now a fresh reference to something called Polar Pacer X.
This is the first time Pacer X has appeared anywhere. There are no regulatory filings and no public mentions, which makes this APK string the only evidence that such a watch might launch soon.
Street X keeps showing up
The INW6J identifier remains present in the latest Polar Flow build. That matters because INW6J has already been confirmed as Polar Street X through FCC paperwork that surfaced in January. Seeing it persist across app versions suggests Street X is still actively tracked inside Polar’s software stack and has not been shelved or renamed internally.
That lines up with what we already know. The FCC documents pointed to a Bluetooth smartwatch with no obvious signs of cellular connectivity. The packaging references and size markings hinted at a lifestyle oriented device rather than a full training tool. A likely price around the low two hundreds in euros also supports that positioning.
Pacer X appears for the first time
The more interesting part of this teardown is the appearance of Polar Pacer X. This is a brand new string that was not present in earlier Polar Flow builds. Unlike Street X it does not yet have an associated device code surfaced publicly and there are no FCC or other regulatory records to lean on.
Nevertheless, the fact that Pacer X shows up in Polar Flow suggests it is far enough along to require software side preparation. Even if the hardware is not yet going through certification.
The Polar Pacer and Pacer Pro were released back in 2022. They represent the company’s entry level running focused watch family, built around GPS training. Adding an X suffix could mean several things. It might point to a design refresh, a lighter urban leaning variant or a trimmed down model.
This is where speculation starts, so it is worth flagging it as such. Polar has used letters sparingly and usually with intent. X could mark a crossover direction, blending training basics with everyday wear. For now there is not enough data to lock that down.
What this says about Polar’s roadmap
Taken together, these two references suggest Polar is working on a broader refresh than just a single lifestyle watch. Street X looks like a new category entry, aimed at everyday activity tracking and brand reach beyond core athletes.
The absence of regulatory filings for Pacer X is important. It tells us Street X is further along and likely to arrive first. Pacer X feels more like a late 2026 product unless filings suddenly appear.
For now, the Polar Flow APK is doing what these teardowns often do best. It confirms internal codenames and product intent before marketing gets involved. Street X is real and still coming. Pacer X is likely real too, even if it is still hiding in the background.
⚠️ An APK teardown helps predict features that may arrive on a service in the future based on work-in-progress code. However, it is possible that such predicted features may not make it to a public release.
