Google Pixel Watch 4 vs Pixel Watch 3: Which smartwatch suits you?

Google Pixel Watch 4 vs Pixel Watch 3: Which Smartwatch Is Right for You?

In this article, we compare the Pixel Watch 4 models with the older Pixel Watch 3.

At first glance, the Google Pixel Watch 4 and Pixel Watch 3 look remarkably similar. Both smartwatches feature the same recognisable circular design, are available in 41mm and 45mm sizes, and offer a wide range of features thanks to the combination of Google Wear OS and Fitbit technology.

However, there are some clear differences between the two generations. The Pixel Watch 4 introduces improvements in display brightness, battery life, performance and connectivity. The Pixel Watch 3, on the other hand, remains an attractive option thanks to its lower price and the fact that many key features remain unchanged.

In the overview below, we compare the most important specifications of the Google Pixel Watch 4 and Pixel Watch 3. This allows you to quickly see which smartwatch best suits your needs, whether you prioritise fitness tracking, health monitoring, everyday usability or overall value for money.

Specifications

Display (Type, Size and Brightness)

This is one of the most noticeable differences between the two watches.

The Pixel Watch 3 features an Actua AMOLED LTPO display with a maximum brightness of 2,000 nits. This was already a significant improvement over previous Pixel Watch models and ensures the screen remains easy to read outdoors.

The Pixel Watch 4 takes things a step further with brightness levels of up to 3,000 nits. Google has also reduced the bezels and introduced a more curved display, giving the front of the watch a more modern appearance.

In everyday use, you'll notice the biggest difference when outdoors, whether you're running, cycling or walking.

Design (Colours, Weight and Dimensions)

In terms of design, both models look very similar. Google has retained its signature circular "pebble-like" design.

Both models are available in:

• 41mm
• 45mm

The 41mm version is particularly suitable for smaller wrists and users who prefer a more subtle watch. The 45mm version offers more screen space and a larger battery.

The Pixel Watch 4 retains its aluminium case but features subtle refinements to the finish and overall comfort. The most noticeable difference comes from the slimmer display bezels.

Battery Life

One of the key improvements of the Pixel Watch 4 is battery performance.

The Pixel Watch 3 typically delivers around one to one and a half days of battery life, depending on the version. The 45mm model benefits from a larger battery.

The Pixel Watch 4 extends this to approximately 30 to 40 hours of use, depending on settings and size. Charging is also faster thanks to the updated charging system.

For users who wear their smartwatch overnight for health tracking, this is a significant improvement.

Sensors

Both models include a comprehensive range of sensors:

• Optical heart rate sensor
• ECG
• Skin temperature sensor
• Blood oxygen monitoring
• Motion sensors
• Altimeter
• Compass

The Pixel Watch 4 uses updated hardware, resulting in improved measurement accuracy.

Health Features

Thanks to Google's partnership with Fitbit, both models rank among the better Android smartwatches for health tracking.

Features include:

• Sleep tracking
• Sleep stages
• Stress monitoring
• Heart rate zones
• ECG

The Pixel Watch 4 mainly improves accuracy and software integration.

Sports Features

• Cycling

The Pixel Watch 4 has the advantage thanks to its improved GPS performance and longer battery life.

For dedicated marathon runners or outdoor athletes, a Garmin Forerunner or Fenix model remains more feature-rich, but for everyday fitness tracking, both Pixel Watches perform exceptionally well.

Smartwatch Features

This is where Google's ecosystem really shines.

Both models work seamlessly with Android and offer:

• Google Wallet
• Google Maps
• Notifications
• Calling directly from the smartwatch
• Music controls

For users primarily looking for Fitbit features, notifications and a stylish smartwatch, the Pixel Watch 3 offers excellent value for money.

The Pixel Watch 4 costs more but delivers meaningful upgrades in key areas such as battery life, display quality and overall performance.
