Caravelle Bulova Watches
1920s-50s Rolex, Rado, Bulova & Caravelle Watches?

I have four old watches: a Rolex from the 20s, Rado from the 30s, Bulova from the 40’s or 50’s and Caravelle mens watch from the 50s. I would have sold them locally because the 2 jewelry store owners told me there that they are genuine BUT could not sell them here since it’s a small midwest town I live in. They both said they would take in a lot of money on the coasts since they are worn for social status. I wonder how much they are worth? How would I go about selling them? And where?

all of them should have serial numbers on them contact the manufacturers and find out what they might be worth from them also contact any antique dealer then put them up on ebay or acution house
