The first and only color illustrated guide to Gruen wristwatches. Over 300 Gruen watches identified correctly with the exact model name, date of production, and much more information on each watch model. Printed in beautiful color, this guide is unique amoung all other watch identification guides. Pictures are life sized to make finding the match to your watch much easier. One addition to this book that you will not find in other price guides is the inflation adjusted price for each watch. The watches have the price they were originally sold at (e.g. 29.95 in 1944), next to that is the price in today's dollars (e.g. $400 for the price of $29.95 in 1944). This makes comparing the value of watches easier to understand. It also gives you the ability to compare watch price of watches that have been made decades apart.
