As with any specialized field, pocket watch collecting has its own terminology, and it is not always easy for the novice collector to understand what the "experts" are talking about. What does it mean to say that a watch has "jewels" or that it is "adjusted"? What is a "hunter case" watch? What's the difference between a railroad "grade" watch and a railroad "approved" watch? What is a "lever set" watch? Isn't "rolled gold" a brand of pretzel? Etc., etc., etc.This booklet is full of all the things I wish somebody had told me when I first started collecting, and which I have shared with many new collectors over the years. Keep in mind that I have tried to keep things as simple and basic as possible for quick and easy comprehension, which necessarily means that this is not a scholarly treatise. But hopefully this will give you enough information to get you started and also give you a clue what those "other" books are talking about.
