This is the 3rd straight year I have received this book. I previously reviewed 09, 10 versions as well. I think this has a few errors with some pics mismatched to some watches, but nothing egregious (still double checking before hitting print would be nice). I think this is a good tool, reference, and picture book - but my advice would be to skip it every other year as due to lack of new pieces every year, there is inevitable repetition. I think some of the updated info in here warrants a better score than 10 version though, so I have this a 4, and 10 version a 3, since they added production info where available and added a few brands. I do wish that more brands could be included and maybe some brands cut back on, but it's a very difficult task to present and gather this info in one volume so I think that WWA does a pretty good job at what it is meant for.
