First, let me welcome you to the Forum!
I think you are likely to see some debates -- especially when companies like Benrus, Bulova, Illinois, and even Hamilton and Elgin are discussed. I think you will first need to establish what makes something "American made", and with that, what constitutes a complete watch and a complete line of watches?
Does a watch have to be entirely made in the US to be considered American? Some of the makers (Benrus, Bulova) had their movements made in Europe. Gruen had a factory in the US, but some of their movements were made here and others were not. Illinois and Hamilton made all of their watch movements here, but did not make their own cases... and Illinois did not even assemble all of their watches into cases in their factory... as many others whos sold through Jobbers also didn't. Illinois was sold to Hamilton in 1928, their Springfield factory was closed in the early 30s, and then the watches were made in Hamilton's Pennsylvania factory... but those made under the Illinois name in the 50s were arguably not truly Illinois or maybe even American. And while no longer American, most may say that the watches made today with the name Elgin, Pulsar, Bulova, and perhaps even Hamilton on the dial are nothing that those great names were in the past... and a Swiss movement in them that was made in China adds a lot of additional questions.
This discussion might be fun to watch...
