UNTESTED - Smart Watches Lot

This listing is for these two smart watches, I seriously know nothing about them. They were given to me by a friend in a box of electronics. The one with the purple band looks like it’s in good condition, the black one might have a crack down the plastic of the screen? I don’t have chargers or any way to test them. Any item specifications on the listing are likely wrong, buy based on the pictures please. No returns, buy assuming they don’t work.
