The size of the display on the Pixel Watch 3 XL is larger compared to the display on the earlier Pixel Watch models2. The Pixel Watch 3 XL features a 1.45-inch display, while the previous Pixel Watch models, including the Pixel Watch 3, have a 1.2-inch panel. This increase in screen size is aimed at providing a better user experience with more visible content and potentially improved readability.

The leaked images of the Pixel Watch 3 XL suggest that there are no major changes to the design compared to the previous Pixel Watch models. The watch will retain the seamless, domed glass design inspired by the continuous surface of a water droplet. It will also keep the digital crown on the right side with a singular button above it.
However, the Pixel Watch 3 XL will be thicker, featuring a 1.45-inch display, compared to the 1.2-inch panel on the Pixel Watch 3 and both previous Pixel Watch devices3. The full dimensions of the watch body will be 45mm x 45mm x 13.89mm. This increased thickness is believed to accommodate a larger battery and more sensors.
Additionally, the leaks indicate that the Pixel Watch 3 XL will come with a larger band attachment system, making the bands for the Pixel Watch 3 and the Pixel Watch 3 XL not interchangeable1. The watch is shown with a slightly updated version of the crafted leather band, but since these are just renders, it's difficult to tell if the band uses a hybrid leather material like the older crafted leather band.

Google has chosen to name the new model the Pixel Watch 3 XL instead of Pixel Watch 3 Pro because the naming scheme suggests that the larger model will come with a larger display (and potentially a larger battery), but likely no other different specs5. The "Pro" naming convention is typically used for devices with significant hardware and feature differences compared to the standard model, and in this case, the Pixel Watch 3 XL may not have enough differences to warrant a "Pro" designation.
