A few more details have emerged about the upcoming Pixel Watch. The watch will reportedly ship with an Exynos 9110 (a 10nm chipset from 2018), but is expected to have a coprocessor for power-efficient operation in standby mode.

This coprocessor has been identified as Cortex-M33 by Max Winebach. The M33’s power draw is measured in micro Watts, so it should be able to last a long time with the 300mAh battery. Aside from the coprocessor, the Exynos 9110 will be connected to 1.5GB of RAM (which is a lot for a watch) and 32GB of storage.

Another interesting note is that the Pixel wearable will be equipped with a linear motor for haptic feedback, which is expected to produce better vibrations than watches with typical vibration motors.

Three versions of the Pixel Watch have been spotted at the FCC so far. One has only Wi-Fi and Bluetooth connectivity (GQF4C), the other two have LTE (GBZ4S and GWT9R). The GBZ4S only supports three bands – 5, 7 and 26 – while the GWT9R supports ten bands: 2, 4, 5, 12, 13, 17, 25, 26, 66 and 71.

The Pixel Watch will have an LTE version, Cortex-M33 coprocessor

The charging disc for the watch will have a USB-C socket, which will allow it to use the same charger as the Pixel phones (which come with USB C to C cables) and indeed the Pixel phones themselves.

Compal is listed as the Pixel Watch ODM. The company has a lot of experience building wearable devices as they have been making Apple watches for years now.

Google has confirmed that the Pixel Watch will arrive this fall (it will be launched alongside the Pixel 7 duo).
