Need to buy Used watch

[newbie9052]

My dad has been going on about his first watches for some time and wants me to find some possible old ones. But I don't know any reliable used watch selling forums or websites. I do not use facebook, hence no access to facebook marketplace. Please advise on your experiences buying used watches.
P.s: He's looking for Favre-Leuba and Nino watches.
On Amazon there are a few listing, but they look suspicious or fake. Hence I've avoided but will take suggestion on genuine sellers if you know any.

Can't say about the rest but someone was selling a Tissot Chronograph a few days ago in the Classified section of the Forum

I did check there, but they only have a few newer watches. I'm looking for those from the mid 80's to Early 90's. Anyways thanks for the suggestion.

As mentioned, I'm looking Favre-Leuba or Nino watches. More of a nostalgic purchase rather than a collectors interest.
