Google Pixel Watch 4 could arrive with new colors and blood oxygen tech

Google’s next Pixel launch event, called Made By Google, will take place on Wednesday, Aug. 20. During the event, we expect to see the debut of the Google Pixel Watch 4 alongside the new Pixel 10 series of smartphones. Pre-orders are said to begin on the day of the launch, with wider availability starting Aug. 28.

As per usual, we've been busy collecting all the latest Pixel 10 leaks and rumors, but the Pixel Watch 4 has also been leaking lately. So, here’s everything we know so far (based on rumors, speculation, and alleged leaks) about Google's upcoming smartwatch and fitness tracker.

It may have a dual-chip setup and a much brighter screen

While the main processor is expected to be the same, the whole setup is getting an upgrade. The watch will reportedly pair the Snapdragon W5+ Gen 1 chip with a new M55 co-processor. The watch may also feature a much brighter AMOLED display with a peak brightness of 3,000 nits.

You'll still have two sizes to choose from

The Pixel Watch 4 is expected to come in two sizes that mirror the Pixel Watch 3 lineup, though leaks suggest the new models will have a thicker watch module and slightly slimmer bezels. The options will reportedly be a 41mm model (codenamed "Meridian") and a 45mm model (codenamed "Canari"). Both sizes are expected to be available in LTE and Wi-Fi-only configurations.

Expect a full rainbow of color and band options

A new leak (courtesy of Arsène Lupin) has revealed the full lineup of rumored colors for the watch itself, which are said to be available for both Wi-Fi and LTE models:

• Black/Obsidian

• Gold/Lemon

• Moonstone

• Silver/Iris

• Silver/Porcelain

A wide range of band materials and colors are also said to be coming, including a two-tone leather band in jade, a metal mesh band in matte black and polished silver, and many others in active, woven, and new gradient stretch styles.

If you're curious what the new Pixel 4 might look like, 91Mobiles shared alleged leaked renders back in April. The watch has the signature circular design, which will be perfectly suited to the new aesthetic of Android 16. Earlier this year, Google showed off new animations and features available with Watch OS 6, so we have some idea what the Pixel Watch 4 experience will be like.

The battery is getting a (small) boost

Android Authority suggests both models will get a battery boost. The 41mm model will reportedly feature a 327 mAh battery (a 7 percent increase over its predecessor's 300 mAh battery), while the 45mm model may see a 9 percent boost to 459 mAh. Faster charging is also expected, potentially through a new wireless charging mechanism that works without magnetic pogo pins, also per Android Authority.

It's also rumored to get new health and safety features

Some reports suggest Google will expand health-tracking capabilities to include a revamped blood oxygen (SpO2) tracking feature that’ll run “continuously,” unlike the current overnight-only version. This would allow the watch to provide alerts when oxygen levels are too low.

The alleged “Notification Cooldown” feature may also make its way to the Watch 4, which limits the number of alerts you receive in a given time period. However, this feature won’t be exclusive to the Watch 4, as it’ll reportedly be available on the Wear OS 6 software.

There’s also a rumored “Emergency Satellite Communications” functionality, but details are scarce.
