The OnePlus Watch 4 has started appearing in leaks and certification listings, which usually means a launch isn’t too far off. But going by what’s surfaced so far, this might be one of those updates that focuses more on refinement than anything dramatic.

The latest bit of info comes from tipster Sudhanshu Ambhore, who spotted the watch on the EMVCo database. That certification mainly relates to contactless payments, and devices tend to show up there fairly close to launch. What’s a little interesting is that there are two model numbers listed: XL905 and XL907. It’s not clear what the difference is yet, but it could point to multiple variants, maybe different sizes or a slightly tweaked version.

As for the hardware, things look… familiar. The Watch 4 is expected to stick with the Snapdragon W5 Gen 1 from last year’s Watch 3. The chip itself dates back to 2022 and has since been succeeded by the newer W5 Gen 2 series, announced in August 2025.

The display also doesn’t seem to change—a 1.5-inch LTPO AMOLED panel with a 466 × 466 resolution, which is basically what we’ve already seen before. There is mention of a slightly larger 47mm case, though, so the overall feel on the wrist might be a bit different.

Battery capacity is said to be 646mAh, which again sounds very similar to the current model. So expectations here should probably be in line with what OnePlus already delivers. One area that does stand out a bit more is durability. The watch is tipped to come with an IP69 rating, which, if accurate, would make it more resistant to harsher conditions than before.

There’s also some mixed info around the software. One leak mentions Wear OS 5, while the certification listing points to Wear OS 6, which seems more likely at this point.

Put together, the Watch 4 looks like a careful update. Not underwhelming, but not trying too hard to surprise either.
