Welcome to the second edition of Elgin Wristwatches: A Collectors Guide. It is 62 pages longer and contains more than 300 new images compared with the first edition, printed just two years ago in 2018. This newest edition corrects a few minor errors contained in the first edition. The 300 new images are the result of an acquisition of source files from the late Roy Ehrhardt Jr. With these additional entries of watches, I am confident that this is the most complete book on the market for identifying vintage Elgin watches.
