sorry for your loss. definitely take some time to grieve and what not and think things through.
it's a tough spot. but when he passed away, things that were his go to his spouse or next of kin. (without a will, i believe thats the legal way). tell his wife the story and if you'd like, offer to buy any watches as a memory if she allows. also, so she doesn't get ripped off incase she doesn't know watches, tell her the prices of those watches used. funerals and suddenly being on one income can be quite a burden on someone financially especially if it's sudden.
I prefer omega over Rolex. And with 300 saved too.
