Google Pixel Watch 3 45mm Review: Features, Specs and More
Google Pixel Watch 3 45mm Review: A Bigger and Smarter Android Smartwatch
Smartwatches are no longer limited to showing the time or displaying phone notifications. A modern smartwatch can help you track workouts, monitor daily activity, manage calls, follow directions, control music, and stay connected without reaching for your phone every few minutes.
The Google Pixel Watch 3 45mm brings these features together in a larger and more practical design. Compared with the smaller 41mm model, the 45mm version offers extra screen space, making notifications, workout data, maps, and apps easier to view.
This model comes in Matte Black and includes an active band. It offers 32GB of storage, Wi-Fi connectivity, Wear OS, health and fitness tracking tools, and a wide range of sensors. It is powered by the Qualcomm Snapdragon W5 Gen 1 platform and includes a Cortex-M33 co-processor to support smooth performance and efficient power management.
In this Google Pixel Watch 3 45mm review, we will look at its design, display, performance, storage, health features, battery life, smart functions, and overall value.

Premium Matte Black Design
The Google Pixel Watch 3 keeps the clean, rounded design that has become familiar across the Pixel Watch range. Its circular body looks simple and modern, while the Matte Black finish gives it a premium appearance without being too flashy.
The dark colour works well with casual clothing, office wear, and sports outfits. It is also a practical choice for users who want a smartwatch that can match different styles.
The 45mm version is larger than the 41mm model, but it remains reasonably light. The extra size mainly benefits the display, giving users more room to read messages, check workout information, and interact with apps.
The included active band has a soft finish and is designed for comfortable daily use. Different band sizes are included, allowing users to choose a better fit for their wrist.
Is the 45mm Size Comfortable?
The larger case can be a major advantage for people with medium or large wrists. Text is easier to read, app controls feel less crowded, and workout information can be viewed without as much scrolling.
However, the 45mm model may feel large on very small wrists. Buyers who prefer a more compact smartwatch should also consider the 41mm version.
Larger and Brighter AMOLED Display
One of the biggest reasons to choose the Google Pixel Watch 3 45mm is its larger display. The watch uses an AMOLED LTPO screen with an adaptive refresh rate that can adjust according to what you are doing. It also supports an always-on display.
The screen can reach up to 2,000 nits of peak brightness, which helps improve visibility outdoors. Whether you are checking a message during the day or viewing workout information in bright sunlight, the display should remain easier to read.
The larger screen is useful for:
Reading notifications and messages
Checking heart-rate information
Viewing workout statistics
Following maps and directions
Controlling music
Using Wear OS apps
Viewing watch faces and widgets
The display is protected by custom 3D Corning Gorilla Glass 5. Its curved shape also helps maintain the smooth appearance of the watch.
For anyone moving from an older smartwatch or a smaller display, the additional screen space can make everyday use noticeably more comfortable.
Performance: Snapdragon W5 Gen 1 and Cortex-M33
The product name mentions the Qualcomm Cortex-M33, but the watch uses a combination of hardware rather than relying on the Cortex-M33 alone.
The Google Pixel Watch 3 is built around the Qualcomm Snapdragon W5 Gen 1 wearable platform and a Cortex-M33 co-processor. Together, these components help manage smartwatch tasks while improving power efficiency.
For everyday use, the hardware supports:
Smooth menu navigation
Quick access to apps
Notifications and messages
Fitness and activity tracking
Health sensor functions
Voice features
Wear OS applications
A smartwatch does not need the same processing power as a phone or laptop. What matters more is how quickly it responds, how smoothly apps work, and how efficiently it handles background activity.
The watch also includes 2GB of SDRAM to support multitasking and app performance.
32GB Storage for Apps and Media
The Google Pixel Watch 3 45mm includes 32GB of internal storage. This provides room for apps, supported downloaded content, watch faces, and system files.
The storage can be useful for people who want to install several Wear OS apps or keep selected content available directly on the watch.
You may use the storage for:
Compatible music and audio downloads
Fitness and productivity apps
Supported offline content
Different watch faces
Additional smartwatch applications
The usable storage will be lower than 32GB because the operating system and preinstalled software take up some space.
Even so, 32GB is a generous amount for a smartwatch and should be enough for most users.
Wi-Fi and Smart Connectivity
This model supports Wi-Fi, Bluetooth 5.3, NFC, and Ultra-Wideband connectivity.
Wi-Fi can be useful when your phone is not nearby but the watch is connected to a compatible network. Depending on the app and connection, you may be able to access online services, sync information, and use supported features.
Bluetooth is important for connecting the watch to an Android phone and compatible accessories. NFC can support contactless payments in regions where the required service is available.
Wi-Fi Is Not the Same as LTE
It is important to understand that this is the Wi-Fi version of the Pixel Watch 3. It does not offer the same independent mobile-network connection as an LTE model.
For many users, this will not be a major concern. The watch can stay connected to a phone through Bluetooth and use Wi-Fi when a compatible network is available.
However, if you want to make full use of mobile connectivity without carrying your phone, you should compare this version with the LTE model before buying.
Health and Wellness Features
Health tracking is one of the main reasons people choose modern smartwatches, and the Pixel Watch 3 includes a wide range of sensors.
Its sensor system includes:
Multi-path optical heart-rate sensor
Red and infrared sensors for SpO2 monitoring
Electrical sensors compatible with the ECG app
Skin temperature sensor
cEDA sensor
Accelerometer
Gyroscope
Altimeter
Barometer
Compass
Magnetometer
These sensors help the watch collect information related to movement, exercise, heart activity, sleep, and general wellness.
Heart-Rate Monitoring
The watch can monitor heart-rate information during the day and while you are exercising. This can help users understand how their heart rate changes during activity and rest.
Heart-rate trends may also be useful when reviewing workout intensity and long-term fitness progress.
ECG Support
The Pixel Watch 3 includes electrical sensors that work with the ECG app where the feature is supported. Availability may depend on the country, software version, age requirements, and other conditions.
Health information provided by a smartwatch should not be used as a replacement for professional medical advice, diagnosis, or treatment.
Sleep and Wellness Tracking
The watch can track sleep-related information and provide insights that may help users better understand their sleeping habits and daily recovery.
The skin temperature and cEDA sensors add further wellness information. However, the availability and meaning of specific insights may vary depending on the region and software features.
Fitness and Activity Tracking
The Google Pixel Watch 3 is suitable for people who want to monitor daily movement and exercise.
It can support activities such as:
Walking
Running
Cycling
Gym workouts
Cardio sessions
Outdoor activities
General daily movement
The built-in GPS system supports GPS, Galileo, and GLONASS. This can help record location, distance, and movement during compatible outdoor activities.
The larger display is particularly useful during workouts because more information can be shown on the screen without repeated scrolling.
Users can review information such as:
Exercise duration
Heart-rate trends
Distance
Movement
Workout progress
Daily activity
The watch also works with Google’s wearable ecosystem and Fitbit-related health and fitness tools. Some advanced features may depend on your region, account settings, software version, or subscription.
Battery Life and Fast Charging
The Google Pixel Watch 3 45mm has a 420mAh battery. According to Google, it can provide up to 24 hours of use with the always-on display enabled and up to 36 hours in Battery Saver mode.
Actual battery life will depend on how you use the watch. Screen brightness, GPS activity, workouts, notifications, installed apps, and network use can all affect battery performance.
The larger battery is one of the advantages of choosing the 45mm model.
Google lists the following approximate charging times:
Around 28 minutes to reach 50%
Around 50 minutes to reach 80%
Around 80 minutes to reach 100%
Fast charging makes daily use more convenient. For example, you may be able to add a useful amount of battery while getting ready in the morning.
The Pixel Watch 3 is not designed for several days of heavy use without charging. However, it offers a reasonable balance between battery life, a bright display, health sensors, connected features, and Wear OS functionality.
Wear OS 5 and Everyday Smart Features
The Google Pixel Watch 3 runs Wear OS 5 and provides access to a wide range of smartwatch apps and Google services.
Depending on your installed apps, phone connection, region, and account setup, you may be able to use features such as:
Phone notifications
Calls and messages
Calendar information
Alarms and timers
Music controls
Navigation
Voice assistance
Smart-home controls
App notifications
Compatible contactless payments
The watch also includes a built-in microphone and speaker for supported calls and voice features.
The side button and rotating haptic crown provide physical controls alongside the touchscreen. The crown can make scrolling through menus and information feel more natural.
Android Compatibility
The Google Pixel Watch 3 is designed for Android users. It works with most compatible phones running Android 10 or newer and requires a Google Account and the Google Pixel Watch app.
It is an especially good match for people who already use a Google Pixel phone, but it can also work with many other Android devices.
Before purchasing, check that your phone, Android version, region, and preferred features are supported.
The Pixel Watch 3 is not designed for iPhone users, so Apple users should consider compatibility carefully before choosing this smartwatch.
Durability and Water Resistance
The Google Pixel Watch 3 has an IP68 rating and 5 ATM water resistance.
These ratings help the watch handle everyday exposure to dust and water. It can be suitable for supported activities such as swimming and exercise when used according to the manufacturer’s guidance.
However, water resistance does not mean the watch is completely waterproof. Resistance can also change over time because of wear, damage, or repairs.
Always follow Google’s care instructions and avoid using the watch in conditions outside its supported limits.
