my dad has a hamilton automatic that he received as a high school graduation present in 1958-59
it still runs today with no problems
today hamilton from what I understand is part of the swatch group and the innards of the automatics and their higher end watches are no longer made in the US, instead they use excellent quality but generic swiss movements often found in much much more expensive swiss watches such as breitling and omega
I have a Hamilton Navy Automatic with a white face it's automatic the back is glass for added bling. I can say it's been great and kept good time. I first saw this watch in the film "into the blue" (with jessica alba) ilked it's simplicity and style.
