Google Pixel Watch 2: A Refined Smartwatch Experience

The Google Pixel Watch 2, launched in October 2023, is a significant refinement of Google's first-generation smartwatch. While it maintains the distinctive, aesthetically pleasing design of its predecessor, it brings a host of internal upgrades and software enhancements that address key areas like performance, battery life, and health tracking. This article provides a comprehensive overview of the Pixel Watch 2's specifications and key features.


Design and Display

At first glance, the Pixel Watch 2 looks nearly identical to the original Pixel Watch. It features the same circular, domed Corning Gorilla Glass 5 face and a 41mm case, though it is now made from 100% recycled aluminum, making it slightly lighter at 31 grams. The watch retains its unique proprietary band connector, which allows for a wide range of official and third-party band options.

The display is a 1.2-inch AMOLED with a resolution of 450x450 pixels and a pixel density of 320 ppi. It's an always-on display with a peak brightness of 1000 nits, ensuring great visibility in various lighting conditions. A subtle but notable change is the refined digital crown, which now offers a smoother and more responsive scrolling experience.

Performance and Battery

One of the most crucial upgrades in the Pixel Watch 2 is the new chipset. It is powered by the Qualcomm Snapdragon W5 Gen 1 with a Cortex-M33 co-processor, a major step up from the older Samsung Exynos chip in the first model. This new processor brings significant improvements in speed and power efficiency, resulting in a much smoother and snappier user experience. It comes with 2GB of SDRAM and 32GB of eMMC storage.

The battery life has been a major focus for Google. The Pixel Watch 2 houses a 306 mAh battery and is rated to last for a full 24 hours with the always-on display enabled, a claim that was difficult to achieve with its predecessor. It also supports faster charging, reaching 50% in about 30 minutes and a full charge in approximately 75 minutes, thanks to a new wired charging system with four pogo pins.

Health and Fitness Tracking

The Pixel Watch 2's health and fitness capabilities are powered by a deep integration with Fitbit. It introduces several new and enhanced sensors:


  • Multi-path Optical Heart Rate Sensor: An upgraded sensor with multiple points of contact for more accurate heart rate readings, even during intense workouts.

  • Skin Temperature Sensor: Tracks skin temperature variation during sleep to provide insights into overall wellness.

  • Continuous Electrodermal Activity (cEDA) Sensor: Measures small electrical changes in your skin's sweat levels to help track your body's response to stress.

  • ECG App: Allows you to take an electrocardiogram to check for signs of atrial fibrillation (AFib).

  • Automatic Workout Detection: The watch can now automatically detect and track common exercises like walking, running, and cycling.

  • Safety Features: New features like "Safety Check" allow you to set a timer for a specific activity. If the timer expires and you haven't responded, your emergency contacts will be notified.

Software and Connectivity

The Pixel Watch 2 runs on Wear OS 4.0, which offers a cleaner, more streamlined interface. This version of the OS brings several key improvements, including the ability to pair the watch with a new phone without needing a factory reset and new apps for Google Calendar and Gmail. It also features a new set of running-specific tools, such as "Heart Zone Training" and "Pace Training," for more effective workouts.

In terms of connectivity, the watch supports 4G LTE, Bluetooth 5.0, Wi-Fi 802.11 b/g/n, NFC for Google Wallet payments, and a full suite of GPS, GLONASS, BeiDou, Galileo, and Quasi-Zenith Satellite for accurate location tracking.
