Description
Produced by the Western Pennsylvania Horological Institute in 1949, the Esembl-O-Graf Chronograph Watch Course covers all of the chronograph movements sold in the United States. If you are looking for detailed illustrations and steps on how to service, adjust or repair a collectible movement, you will more than likely find what you need in this set (full listing of calibers below).
It can bit a bit tricky to find hard copies as the course is no longer in print, though best options are:
– Hard copies, both individual volumes and the full set: eBay or forums
– Electronic form (PDF, via CD-ROM): eBay
– Online (free): Gisbert A. Joseph web site, though you will need to click through each page one-by-one, which can get rather tedious
The course spans 28 volumes and over 2000 pages, and original copies were produced in softback.
