Maaaaaaannnnnnn if this was a legal advice subreddit I would have very different advice but since this is r/Watches I would pick 1 or 2 watches that you have fond memories of him with, and give the rest to his wife because its the right thing to do and legally its her property. It's HIS WIFE. His money and property becomes hers on his unfortunate passing. She also is grieving and will probably need the money long term if he was the main provider.
