Both watches run Wear OS, with the Pixel Watch 3 on the newer Wear OS 5.0. They share the same Qualcomm SW5100 processor, but the Pixel Watch 3 offers larger AMOLED displays (1.27 inch for 41mm, 1.46 inch for 45mm) compared to the Pixel Watch 2’s 1.2 inch. The Pixel Watch 3 includes additional sensors (gyroscope, pulse oximeter, barometer) and boasts a longer battery life of up to 46.5 hours versus 33 hours for the Pixel Watch 2. Both are IP68-rated for dust and water resistance up to 3 meters.

Processor

Both the Pixel Watch 3 and Pixel Watch 2 feature identical hardware: a Qualcomm SW5100 processor, Cortex-M33 co-processor, 2GB RAM, and 32GB storage. This means no performance boost for the newer model.

Design and Sizes

The Pixel Watch 3 retains the sleek, round design of the Pixel Watch 2, with an aluminium back, Gorilla Glass 5 front, rotating crown, and optical heart rate sensor. Google claims the Pixel Watch 3’s heart rate sensor is more accurate due to an improved algorithm, despite identical hardware.

The key upgrade is the new 45mm size option for the Pixel Watch 3. The 41mm version matches the Pixel Watch 2’s size, making their straps interchangeable, but the 45mm model requires new bands. The 41mm Pixel Watch 3 has 10% more screen area due to thinner bezels, while the 45mm offers 40% more, allowing extra watch face complications, activity shortcuts, and weather data without scrolling.

Display

The Pixel Watch 3 features smaller bezels for a larger, brighter display, reaching up to 2,000 nits compared to the Pixel Watch 2’s 1,000 nits. Both maintain 320 pixels per inch for equal sharpness and cover the DCI-P3 colour spectrum.

Battery Life

The Pixel Watch 3 offers up to 46.5 hours of battery life, surpassing the Pixel Watch 2’s 33 hours, thanks to features like automatic display dimming during sleep. It also charges 20% faster, reaching a full charge in about an hour. Both are rated for 24 hours with always-on display enabled.

Connectivity

The Pixel Watch 3 introduces an Ultra-Wideband (UWB) chip for more reliable phone unlocking over longer distances compared to the Pixel Watch 2’s Bluetooth. UWB also enables car unlocking for compatible BMW and Mini models. Enhanced Google integration includes live Nest camera feeds, Google TV control, offline maps, and access to the Pixel Recorder app from your wrist.

Verdict

The Pixel Watch 3 offers improvements like a larger, brighter display, UWB connectivity, and longer battery life. It’s ideal for those wanting the 45mm size or a UWB-compatible phone. However, the Pixel Watch 2 remains a strong, budget-friendly option at £239. If you already own a Pixel Watch 2, upgrading may not be necessary unless the 45mm model is a must-have.
