Foldables were the star of the show at Samsung’s Galaxy Unpacked event on 11 August, but we shouldn’t forget about the wearables. The Korean giant revealed the regular Galaxy Watch 4 and high-end Watch 4 Classic, both of which bring some big changes to the table.

Chief among these is a return to WearOS software, produced in collaboration with Google. The tweaked version Samsung is using is officially known as ‘One UI Watch’, but the Watch 4 and 4 Classic are the first smartwatches to run the revamped operating system.

Samsung’s new Exynos W920 processor also makes its debut here, becoming the first 5nm chip designed for wearables. The wide-ranging health and fitness features include a new body composition metric, which includes indicators of bone density and water retention.

However, it’s the Watch 4 Classic that can be seen as a direct successor to last year’s device, retaining the physical turning crown we saw on the Watch 3. The regular Watch 4 replaces this with haptic feedback, allowing for significantly slimmer bezels. There’s also some variation in sizing, as we explain below.

Here's everywhere you can buy your Galaxy Watch 4 right now.
