Google offers different types of wearables for users with different needs, and the Fitbit Edge and Pixel Watch 3 are good examples. Although both devices combine fitness tracking with health-monitoring capabilities, they serve different purposes. The Fitbit Edge is a dedicated fitness tracker focused on activity monitoring, health insights and extended battery life. The Pixel Watch 3, on the other hand, is a full-fledged smartwatch that combines Fitbit fitness features with Wear OS applications, communication tools and Google services. Here is how the two Google wearables compare.

Google Fitbit Edge vs Google Pixel Watch 3

Design & Build

The Google Fitbit Edge features a slim rectangular design with a 1.34-inch display, a 100% recycled aluminium case and a silicone band. Weighing just 17.7g without the band, it is designed for lightweight, all-day wear, including during sleep and workouts. The Pixel Watch 3 takes a more traditional smartwatch approach with a circular design, an aluminium frame and Gorilla Glass 5 protection. Its 45mm version weighs 37g without the band, making it noticeably heavier than the Edge. Both devices offer 5ATM water resistance and IP68 protection, making them suitable for everyday activities and workouts.

Key Difference: The Fitbit Edge prioritises lightweight comfort and fitness tracking, while the Pixel Watch 3 offers a conventional smartwatch design.

Display

The Fitbit Edge features a 1.34-inch Hybrid OLED colour display with always-on functionality and adjustable brightness. Its rectangular screen provides quick access to workout statistics, health information and everyday activity data. The Pixel Watch 3 features a 1.4-inch circular LTPO AMOLED display with a resolution of 456 × 456 pixels, approximately 320ppi and peak brightness of 2,000 nits. It also supports an adaptive refresh rate of 1–60Hz. The Pixel Watch 3 provides a more detailed viewing experience for notifications, maps and applications, whereas the Edge focuses on making fitness information easy to read at a glance.

Key Difference: The Pixel Watch 3 has a higher-resolution, brighter display with adaptive refresh technology, while the Edge offers a larger viewing area than previous Fitbit trackers.

Battery Life

Battery life is one of the biggest differences between these devices. The Fitbit Edge features a 65mAh rechargeable battery rated for up to seven days of usage. It supports magnetic charging, with a full charge taking approximately 90 minutes. A five-minute charge can also provide up to one day of battery life. The Pixel Watch 3 45mm comes with a considerably larger 420mAh battery but offers up to 24 hours of usage with the always-on display enabled and up to 36 hours in Battery Saver mode. Its larger display and full smartwatch operating system mean users will need to charge it considerably more frequently.

Key Difference: The Fitbit Edge is designed for extended battery endurance, while the Pixel Watch 3 prioritises a broader smartwatch experience at the cost of battery life.

Health Tracking

Both devices offer extensive health-monitoring capabilities, including continuous heart-rate tracking, blood oxygen monitoring, ECG functionality, skin temperature tracking and sleep monitoring. However, their approaches to health insights differ. The Fitbit Edge includes Google Health Guardian features that monitor blood pressure and insulin resistance trends, alongside high and low heart-rate alerts. It also tracks HRV, sleep patterns and menstrual cycles. The Pixel Watch 3 combines Fitbit health tracking with additional sensors, including an electrical skin conductance sensor for body-response tracking. Both offer comprehensive health information, although the Edge places particular emphasis on dedicated wellness monitoring and long-term health trends.

Key Difference: The Edge focuses on additional wellness trends and dedicated health insights, while the Pixel Watch 3 combines health monitoring with a broader range of smartwatch sensors.

GPS & Navigation

Both wearables feature built-in GPS, allowing users to track outdoor workouts without carrying a smartphone. The Fitbit Edge supports GPS and Galileo, with Google’s precision GPS technology offering up to 40% improved tracking accuracy compared with previous Fitbit trackers. It also includes an altimeter for measuring elevation changes during outdoor activities. The Pixel Watch 3 supports GPS, GLONASS and Galileo, with additional satellite systems available in supported regions. More importantly, it offers Google Maps navigation directly from the wrist, making it useful for following directions while walking, running or exploring unfamiliar places.

Key Difference: Both support standalone GPS tracking, but the Pixel Watch 3 offers a more comprehensive navigation experience.

Sports & Training Features

The Fitbit Edge is built around dedicated fitness tracking, supporting more than 50 exercise modes and automatic recognition of up to 100 workouts. It tracks workout metrics, pace, elevation, VO2 Max, Active Zone Minutes, Cardio Load and Readiness Score. The Pixel Watch 3 offers more specialised running tools, including custom workouts, interval training, pace guidance and running-form measurements such as cadence, stride length, vertical oscillation and ground contact time. Both can support regular exercise routines, but their strengths differ. The Edge focuses on broad fitness monitoring, while the Pixel Watch 3 provides more detailed running analysis.

Key Difference: The Edge focuses on everyday fitness and activity tracking, whereas the Pixel Watch 3 offers more specialised running analysis and training tools.

Smart Features

The Pixel Watch 3 has a significant advantage in traditional smartwatch functionality. Running Wear OS 5, it supports Google services and a wider application ecosystem, including Google Wallet, Google Maps, Google Assistant and smartphone notifications. Its built-in microphone and speaker also allow users to handle calls and voice interactions. The Fitbit Edge offers a simpler experience with call and message notifications, quick replies, media controls, alarms, timers and Google Maps. It also supports customisable watch faces and interchangeable bands. While the Edge provides useful everyday conveniences, it does not offer the same full Wear OS experience as the Pixel Watch 3.

Key Difference: The Pixel Watch 3 offers a full smartwatch operating system and broader app support, while the Edge focuses on essential everyday features.

Outdoor Features

Both devices offer features for outdoor activities, including GPS tracking, elevation monitoring and 5ATM water resistance with IP68 protection. The Fitbit Edge combines its lightweight construction with built-in GPS and an altimeter, making it suitable for running, walking, hiking and other fitness activities. Its longer battery life is also useful for people who regularly track outdoor workouts. The Pixel Watch 3 adds a compass, barometer, altimeter and broader satellite positioning support. Combined with Google Maps, these features make it a more versatile companion for outdoor navigation and location-based activities.

Key Difference: The Edge is better suited to lightweight outdoor fitness tracking, while the Pixel Watch 3 offers additional navigation and environmental sensors.

Which One Should You Buy?

Choosing between these Google wearables depends on what you expect from a wrist-worn device. The Fitbit Edge is suitable for people who primarily want to monitor their fitness, sleep, recovery and overall health without charging their wearable every day. Its lightweight design, seven-day battery life and dedicated health features make it a practical everyday fitness companion. The Pixel Watch 3 is better suited to people who want a traditional smartwatch with fitness tracking as an additional capability. Its Wear OS platform, Google services, communication features and advanced running tools make it more versatile for everyday use.

Choose the Fitbit Edge for: Dedicated fitness tracking, lightweight comfort, extended battery life and health-focused monitoring.

Choose the Pixel Watch 3 for: Smartwatch applications, smartphone integration, calls, navigation and advanced running features.
