Illinois turned out about five million watches before being sold to the Hamilton Watch Co. of Lancaster, PA, in 1928. Hamilton continued production in Springfield for several years and then moved operations to the Hamilton plant in Lancaster. Illinois watches continued to be produced as different designs from Hamilton watches until 1949 when the name was retired. However, Hamilton occasionally produced a few Illinois-named watches in the 1950s (and possibly later) to maintain ownership of the rights to the Illinois name and trademarks. Here is one of the watches produced about this time and a part of history.
