I actually thought the Hamilton might be a womans, but the lugs are the same as on my Seamaster. I am going to try to dig up some more info about it. I must admit as the clothing finds have been coming slower I have been exploring some of the nether regions of the thrifting world. It has yielded some interesting Art, Cologne/Perfume, cookware. Also found a mostly full bottle of Creed Tabarome and #4/195 of this print.
