An important resource to learn more about different IWC pocket watches is the historical literature. Fortunately, several catalogs, price lists and parts supply books still exist and are available here. These primarily reflect the different movement calibres produced by IWC and were primarily intended for watchmakers and retailers. The catalogs also show a few models and frequently include calibre diagrams. One should realize that numerous dial and case-style variations were produced, and only a few were depicted in the catalogs.
