The Pixel Watch 3 XL shares a design language with the Pixel Watch 3 that we saw in the leaked render, as well as the Pixel Watch 2 and the original Pixel Watch before that. It will feature a curved glass finish, a digital crown on the right, and a single button directly above it.
The report suggests that the Pixel Watch 3 XL's dimensions are 45mm, or 45mm x 45mm x 13.89mm, compared to the Pixel Watch 3's 40.79 x 40.73 x 14mm dimensions. In comparison, the Samsung Galaxy Watch 5 Pro and the Apple Watch Series 9 are also available in 41mm and 45mm sizes.
Since the report states the company will reportedly market the watch as an "XL" variant rather than a "Pro" model, it suggests that there won't be any performance upgrades over the standard Pixel Watch 3.
However, with bigger dimensions, Google should have the room to fit in a larger battery on the XL model. From the renders, we can see that the device will continue to use the pogo pin-based charging that we get with the previous generation models.
Moreover, the report mentions that the XL model will have a bigger 1.45-inch display than the standard variant's 1.2-inch screen. Furthermore, it also suggests that the Pixel Watch 3 will have a smaller band attachment system than the XL model. It means you might be unable to interchange the Pixel Watch 3 XL's bands with the Pixel Watch 3 or the previous models.
The original Pixel Watch launched in October 2022, and the Pixel Watch 2 arrived in October 2023. With October just a few months away and leaks of the Pixel Watch 3 family surfacing online, we expect to learn more about the lineup in the coming days.
