Samsung Galaxy Watch 3 Variants

A couple of weeks back, Samsung unveiled its next-generation smartwatch, the Galaxy Watch 4, alongside other devices in the Galaxy family. The new Galaxy Watch 4 is coming in to replace the Galaxy Watch 3 Samsung released a year ago. There are plenty of differences between the Galaxy Watch 4 Classic and its predecessor, the Galaxy Watch 3. And in this article, we will be taking a look at their differences.

But before we get to it, you should know that Samsung made some tweaks to the names of its smartwatches. During its last Unpacked event, Samsung unveiled the Galaxy Watch4 and Galaxy Watch 4 Classic.

The Galaxy Watch 4 Classic features some very notable design changes from the Galaxy Watch 3. While the buttons are still located on the right edge, just like the Galaxy Watch 3, they are designed a little differently: they are flatter and more elongated. The Galaxy Watch 3, on the other hand, features circular protruding nubs.


The Galaxy Watch 3 is powered by Samsung’s own operating system, Tizen OS. However, Samsung has now partnered with Google and all of Samsung’s smartwatches, including the Galaxy Watch 4, are now powered by Google’s Wear OS. The importance of this upgrade is that the new Google OS is that it opens the door to a larger app library for Samsung smartwatch users than Tizen.

The Galaxy Watch 3 features 1GB of RAM and 8GB of storage space, which we felt was more than enough for apps and offline music files, at the time. The Galaxy Watch 4 Classic, on the other hand, is packed with 1.5GB of RAM and 16GB of storage, to cover the extra apps that’ll come with the Wear OS.

When the Galaxy Watch 3 launched a year ago, it was the premium smartwatch from Samsung and it sold for $399. The new Galaxy Watch 4 Classic starts at $350, $49 lower.
