Even though the Pixel Watch 3 is still relatively new, rumors about its successor are already heating up. Fresh leaks have stirred excitement around the rumored Pixel Watch 4, thanks to a collaboration between well-known leaker Steve Hemmerstoffer (aka OnLeaks) and 91mobiles, who recently shared renders of the potential new model.

The design shown in these unofficial images sticks to Google’s recognizable circular watch face, but with a slightly chunkier frame. While nothing has been confirmed, this added thickness has led some to speculate that the Pixel Watch 4 could include a larger battery—something users have been hoping to see.
One especially interesting detail? The back of the watch seems to be missing the four charging pins seen in the Pixel Watch 3. This has fueled speculation that Google might be shifting to wireless charging for the first time in its Pixel Watch line. It’s worth noting, however, that these are based on visual clues and have not been confirmed by the company.
Adding more intrigue, the renders show two mysterious buttons near the speaker. What these buttons do is still unknown. Some believe they could be new shortcuts or tools tied to fitness tracking or smart features, but at this stage, that remains purely rumor.
As for performance, there’s no official word yet on what chipset will power the device. The Pixel Watch 3 runs on Qualcomm’s Snapdragon W5 Gen 1, but some reports suggest Google has been developing a custom Tensor chip for wearables. Whether it debuts with the Pixel Watch 4 or gets pushed to a future release—likely the Pixel Watch 5—remains to be seen.
Google has not confirmed any specs or design details yet. However, if the company follows its usual product schedule, the Pixel Watch 4 could arrive later this year alongside the Pixel 10 smartphone series. Until then, take all current details with a grain of salt—while these leaks offer exciting hints, they’re still unconfirmed.
