Jomashop Jomashop.com Jomashop sold me a defective, possibly counterfeit Swiss watch, won't take it back Brooklyn NY

I ordered a Longines Hydroconquest from Jomashop. It did not work when it arrived. I took it to a watch store and they said it was defective. The watch store was closed when the watch arrived due to the COVID-19 epidemic, and opened two weeks later.  The watch was not worn before I took it to the store because it was broken and also needed to be sized. 

I tried to return it within the 30-day period after receiving it, but Jomashop won't take it back, claims it was scratched, even though it could not have possibly been worn since it was not working and needed to be sized.  I've never heard of brand new Swiss watches that arrive broken from reputable, authorized dealers.  My concern is Jomashop sold me a counterfeit, broken watch.
