Not sure about watches, I can confirm that Samsung is able to blacklist phones though, like said above, however even if SE'd/refunded they don't always do that.
To be more on the safe side, I always recommend SE'ing from retailers instead of manufacturers directly. Ofcourse it depends on the product, but most of the time they can't lock a product themselves and they have to reach out to the manufacturer, which they almost never do.
