Considering your friend had a 200k watch collection, I assume he was well off and left his widow well endowed. If that's the case, I'd say keep them. Your friend found an appreciation for them that obviously she does not have, so in his spirit, enjoy them. If I were the friend who died, and I saw my watches sold off by my lady to buy new purses, shoes, etc. (which being honest would probably just get worn once, then sit in boxes in the closet) I'd for sure come back and haunt you.
