The Pixel Watch 4 is thought to retain the choice of 41 and 45 millimeter (mm) case sizes introduced with the previous generation - although it might be the first to get customizable strength-training tracking and real-time run coaching.
Prospective customers interested in those features might also be able to invest in an official Google Sport Band for either size of the wearable, according to Android Headlines.
The blog's new images based on the latest Pixel Watch 4 predictions suggest that they will come with Apple Watch Nike Sports Band-style ventilation and come in colors such as Iris, Lemongrass Limoncello and Indigo.
They might be joined by more 'everyday' or Active bands in the same colors, as well as more sober shades such as Moonstone, Porcelain, and Obsidian.
The Pixel Watch 4 itself is thought to become available in Black, Gold, Silver, and more Moonstone from its launch on August 20, 2025.
2 of those options (the Silver and Black) are also portrayed as using the new and allegedly "25%" faster Pixel Watch Charger, apparently designed to hold the wearable upright on 1 side via dedicated pins as it powers back up.
