What’s the Difference?

Samsung Galaxy Watch vs Galaxy Watch 3 Features Compared
  1. Improved Design For Galaxy Watch 3
  2. The Galaxy Watch 3 looks almost like it’s predecessor, except that it’s now slimmer, more compact, and weighs a little less. The physical rotating bezel present on Galaxy Watch is also present on Galaxy Watch 3 but is now smoother and slimmer. Moreover, you can navigate the watch with only the rotating bezel without touching the display which isn’t possible with its predecessor.

    Galaxy Watch 3 comes in two sizes just like its predecessor. It’s however now slimmer 41/45mm compared to 42/46mm, yet has a slightly larger 1.2/1.4 inches display compared to 1.2/1.3 inches of Galaxy Watch. It’s the same AMOLED that powers the display of both smartwatches. Corning Gorilla Glass DX has also been used to protect the respective screens.

  3. More Fitness Tracking Features on Galaxy Watch 3
  4. Galaxy Watch 3 comes with more fitness tracking features that makes it a more comprehensive health tracker than it’s predecessor. Blood oxygen tracking, VO2 Max., running coach, and incidental fall detection are the new health-tracking present on Galaxy Watch 3 but not on Galaxy Watch.

    Moreover, about 120 home work-out videos have been introduced to Galaxy Watch 3. You can cast these videos to your smart TV and see your tracked metrics in real-time.

    Although, each of these two will track your steps, heart rate, calories, stress, and more. And there is an inbuilt GPS on both devices that enables you to track outdoor activities. There are also many preloaded work-out modes to choose from. Galaxy Watch 3 has been cleared by the FDA for ECG tracking, while it can also monitor blood pressure.

  5. Increased Storage Capacity
  6. Galaxy Watch 3 has twice the storage capacity of its predecessor. While it has 8GB storage capacity, Galaxy Watch has just 4GB. This of course allows you to store more of your favorite tracks and apps on the watch.

  7. Newer Tizen 0S 5.5 Platform
  8. Both smartwatches are powered by Samsung’s Exynos 9100 chip that’s built on a 10nm fabrication process. However, Galaxy Watch 3 runs on Tizen 5.5 out of the box which has added more interesting features that can improve user’s experience. Moreover, with a higher 1GB RAM on Galaxy Watch 3, it has a better performance when compared to Galaxy Watch.

  9. Galaxy Watch 3 Has a Shorter Battery Life
  10. The price to pay for the slimmer, lighter, more compact and larger display of the Galaxy Watch 3 is that it has a shorter battery life than it’s predecessor. The Galaxy Watch 3 comes with a smaller 340mah battery capacity compared to 470mah of Galaxy Watch. As a result, it has about a 2 days long battery life compared to up to 4 days of Galaxy Watch. This is still very commendable, especially when compared to Apple Watch 5 or Fossil Gen 5 both of which can barely boast up to a day battery life.

Which is Better?

No doubt, these two are some of the best on the market, but Galaxy Watch 3 is a more sophisticated smartwatch than Galaxy Watch.

Although it cost a lot more, if the higher storage, improved performance, more fitness tracking features, and more comfortable wear matters more to you and you’re willing to compromise on battery life, then Galaxy Watch 3 is a better bargain.

However, Galaxy Watch is still a comprehensive fitness tracker with a sophisticated design and longer battery life. It’s a great choice if you’re tight on budget.

Should You Upgrade?

I already own the Galaxy Watch as well as Active 2 which I’ve been using for a while now, but I’ll be getting the Galaxy Watch 3 just to experience what’s new on it. If you feel the same way, it’s worthwhile upgrading, otherwise, the Galaxy Watch is still one of my favorite Samsung smartwatches.
