I have just posted on the NAWCC Encyclopedia a full copy of my booklet "100 Plus Years of Railroad Watches and Railroad Watch Standards in North America". This is a copyrighted book (1999) and it is presented there for personal use only. Also included is an appendix of many important ads, etc., that was added in 2012. 100 Plus Years of Railroad Watches and Railroad Watch Standards in North America This work (and the appendix) is based on factual period information NOT modern day hearsay (emphasis added and indeed required). Much of the research for it was done in the dusty stacks of libraries (before the internet explosion). Even today there is a great deal of information and data presented herein that has yet to make its way to the world wide web. Many ads and the like are from my personal collection of horological ephemera that includes some publications that are virtually unobtainable (so far as I know). For example, among the period journals examined are The American Jeweler, The Watchmaker and Metalworker, and The Chicago Jeweler. There's even a letter from 1973 wherein Jules Racine describes their railroad wrist watch. If you find this work useful and interesting you might consider making a donation to the NAWCC. I have been a member of this organization for over 30 years.
