Samsung always increases the screen sizes of its smartwatches, and the trend may continue this year too. According to the Ice Universe, Samsung will increase the display size of the Galaxy Watch 6 Classic. The watch will have a 1.47-inch screen more than Galaxy Watch 5 series. For your information, Galaxy Watch 5 & Watch 5 Pro have a 1.4-inch screen, and Watch 4 has a 1.2-inch screen.
If you think it will not make difference, then in numbers, it will increase screen area by 10%, which is a huge difference. Rumors also predict that the Galaxy Watch 6 Classic will get a physical rotating bezel, so it might also increase case size. If the case size increases, then some users might not like it.
This information is only for Watch 6 Classic or Watch 6 Pro, the regular Galaxy Watch 6 may revive the same 1.4-inch screen size. With the upcoming Wear OS 4.0-powered WatchOS 2.0 version, Samsung will launch its wearables in August 2023.
