Query: Not worth being published once a year

I am an old time collector and have had my share of excellent watches. NAWCC # 29290. This book was a welcome addition to my library at the beginning but it has become a yearly event and not as welcome as the Capistrano's swallows.A little tweaking here and there, a slight increase in price, a few new watches pictures and... A La Kazam ! A new edition is born. It is a good source of informations but I think once every 5 years would be sufficient. The prices DO NOT reflect the real world prices and eBay prices give a better idea. I have seen watches in this book listed at 1000 dollars in mint condition go on eBay in the same condition for 300 and vice versa. The authors also run a very active watch business and the book is self serving. Once every 5 years would be very sufficient.
