Hello, I have registered to exploit your knowledge....as I have none in the field of watches

A friend passed away last year and I'm working with his father to sort out his stuff. I'm fine with the majority of it as we had a common interest in motorcycles.
There are four possibly Breitling watches which I need help to identify as to if they are and if so what model and approx year if possible.
Should I start 4 posts in the event some or all are fakes/replicas and thus moved to the correct subforum or should I do it as one post?
Thank you
Blaine
P.S. Spell checker does not recognize Breitling
