The Galaxy Watch 3 brought back something that Samsung smartwatch fans had been missing for a couple of years: the physical rotating bezel. It was otherwise quite similar to the Galaxy Watch Active 2 with almost the same specs and features. The device did come with some new health-related features such as fall detection and blood oxygen saturation measurement.
With the Galaxy Watch 4, Samsung has made some of the biggest improvements to its smartwatches in years. The Galaxy Watch 4 is also a fundamentally different watch in that it runs Android, not Tizen.
Galaxy Watch 4 vs Galaxy Watch 3
Samsung is offering its new smartwatch in two models – the Galaxy Watch 4 and Galaxy Watch 4 Classic. The specs and features are exactly the same. The only difference is the physical rotating bezel that's only present on the Classic.
The Galaxy Watch 4 Classic is available in 42mm and 46mm sizes with a 1.19-inch and 1.36-inch display respectively, negligibly smaller than the 1.2-inch and 1.4-inch displays on the 41mm and 45mm Galaxy Watch 3. Both new models are slimmer than the Galaxy Watch 3, though.
An interesting point to note in this Galaxy Watch 4 vs Galaxy Watch 3 comparison is that the new models have much higher resolution displays. They also come with the first 5nm processor on a Galaxy Watch, the Exynos W920.
The CPU is 1.25x faster and boasts up to 10x smoother graphics performance. The new smartwatches also have 1.5x the amount of RAM, 1.5GB compared to 1GB on the Galaxy Watch 3. They also boast double the storage at 16GB compared to 8GB on the outgoing model.
Samsung's new 3-in-1 BioActive Sensor allows for enhanced health and fitness features that were not present in earlier models. This includes detailed body composition analysis, enhanced fitness tracking, advanced sleep management with snoring detection and continuous blood oxygen tracking. This is in addition to all of the features found on the Galaxy Watch 3 such as ECG.
Since the Galaxy Watch 4 runs on the new Wear OS platform co-developed with Google, it's also capable of running Android apps. This gives it a major advantage over the Galaxy Watch 3 which runs on Tizen and is therefore on the outside of Google's app ecosystem. The Galaxy Watch 4 is clearly the new champion among all of Samsung's watches.
