I got a galaxy watch 6 in that particular charger as well. You're going to have to do some modification.. A round watch is too big to center itself on the watch charger.
I've never seen a UAGA s24 ultra with lens protector something similar with SupCase. I skipped UAG and use Supcase instead for various reasons such as UAG is more on style but supcases are also stylish and more functional.
