I love the new 43 mm galaxy classic. It is much smaller than the original 47 mm classic that I had from many years ago. I also like the newer mesh band which allows for an infinite number of fit settings.
I had a Samsung Galaxy 3, Frontier which finally gave up the ghost and bought the Galaxy Watch 6, Classic, Bluetooth. Nice watch, but has so many features/capabilities I'll never use them all. As I did with the Frontier, I've ordered a third party, metal watchband; not a fan of leather or rubber watchbands. Get one, you won't be sorry.
