Earlier this month, Google announced multiple new devices at its Made by Google event, including Pixel 11 phones and the Pixel Watch 5. Back in May, the company also released its screenless Fitbit Air health tracker.

But we still haven’t heard anything about the new mystery product that’s appeared in recent Google ads.

A Reddit thread posted on Saturday revealed a Google Pixel ad on YouTube featuring the new Pixel 11 series, the Pixel Watch 5 and an unknown wearable that looks like a cross between the Fitbit Charge 6 and the Watch 5, standing out with its oblong screen with rounded edges in fog white. Sponsored by Google Australia, the ad’s caption reads: “The ultimate power trio for your wrist, ears and hands. Preorder Pixel devices now.”

Some speculate that the product may be the Fitbit Charge 7 or a rebranded Pixel Watch series. Or maybe it’s an entirely new fitness tracker?

A Google representative didn’t immediately respond to a request for comment.

That wasn’t the only Google Australia ad featuring the surprise device. The mystery wearable appears in another ad displaying the Pixel 11 phones, Watch 5, Pixel Buds Pro 2, Pixelsnap phone cases and Watch loop bands in the new olive green color.

Real or fake?

Some Reddit commenters wondered whether this mystery product was a mistake caused by an AI hallucination — an error caused by generative artificial intelligence.

But this also wouldn’t be the first time Google sneaked an unreleased product into its promotional content. Back in March, two months before its release, the Fitbit Air was spotted in a paid partnership video with NBA star Steph Curry, who is also a Google performance adviser.

It would seem that Google is releasing a new wearable, potentially as part of its Pixel line, in both fog and olive colors. If the time between these ad leaks and the device’s release follows the same pattern as the Fitbit Air’s appearance in Curry’s video, we should know more in the coming weeks.
