Hadley (?) A very clean watch , dial probably refinished. Have been unable ever to find a corresponding advert . This is the first Bulova that I bought, back in 2015, starting off my collection, as my late wife worked for Bulova in London's Soho in her teens back in the 60s . She said she probably scratched more watches putting on straps and bracelets than was good for her career prospects there !
I find a couple of options for this one; both Hadley and Providence share the same ref# 31717, and both are in the 1955 and 1958 pricelists, Providence only in the 1954 Pricelist..
According to the LineBooks, in 1955 only the Providence is listed; in 1956 neither are listed; and in 1957 only the Hadley is shown. I do not find any ads for either of these models.
Since Providence is listed first and appears to have been replaced by Hadley, I would say in 1952 Providence was likely the model name.
