Jan Lot 4- B & B Glass Watch Crystal Reference Book

This is a good clean B&B Crystal very early wristwatch catalog. This catalog is one of the earliest I have ever owned or sold. It is pristine. This catalog will help you identify the proper crystal to insert into your ladies' or men's vintage mechanical wristwatch. This is a catalog you will go to time and time again and be glad you have it. The information inside this catalogue is invaluable and the condition is amazing. Add this catalog to your horological library and have the information you need on vintage crystals. This reference catalog has a good factory reference list and is strictly for glass wristwatch crystals.
