A fresh leak has revealed nearly everything there is to know about Google’s upcoming Pixel Watch 4, with new case colours, sizes, and band options tipped to launch alongside the Pixel 10 on August 20.

According to reliable tipsters Roland Quandt and Arsène Lupin, the Pixel Watch 4 will be offered in both 41mm and 45mm sizes, with Wi-Fi-only and LTE versions available.

The design appears largely unchanged from last year’s Pixel Watch 3, though leaks suggest a slightly thicker case (14.3mm) and slimmer bezels. New to the design are two side buttons flanking the speaker.

Five case colourways are expected: Obsidian (black), Lemon (yellow), Moonstone (grey), Iris (purple) and Porcelain (off-white). These will be paired with an expanded range of band styles and colours in what appears to be a full lineup refresh for 2025.

The updated bands include:

  • Active Bands in Iris, Lemongrass, and Moonstone

  • Active Sport Bands in Indigo, Lemongrass, Moonstone, and Peony

  • Gradient Stretch Bands in multi-tone combos like Obsidian/Hazel and Peony/Iris

  • Crafted Leather Band in Moonstone

  • Metal Mesh Bands in Matte Black and Polished Silver

  • Performance Loop Band in Moonstone

  • 2-Tone Leather Band in Jade

  • Woven Band in Indigo

While Google has yet to confirm any details, the consistency across multiple sources adds credibility to the leak.

If history repeats, an official reveal is expected next month alongside new Pixel phones, and potentially more Wear OS updates in the pipeline.
