(Pocket-lint) – Samsung announced the next generation of its Galaxy Watch in the form of the Galaxy Watch 4 and Watch 4 Classic in August 2021.
The two latest smartwatches succeed the Galaxy Watch 3 that arrived in August 2020 and the sleeker, bezel-free Samsung Galaxy Active 2 from August 2019, but how do they compare?
Here is how the Galaxy Watch 4 and Watch 4 Classic compares to the Galaxy Watch 3 and Active 2.
