The 'Wristwatch Annual' has entered the 14th iteration by now, so it must be doing something right. In essence it collects some of the most important new launches of the year into one book and adds a selection of articles as a complement.
After a handful of introductory notes on how to use the manual, the book launches into some introductory articles, this year on what can be expected from the independent haute horologie boutique manufacturers (good) and why fake watches are evil and why one should only buy watches in manufacturer owned / endorsed outlets (with many correct points raised but a tonality clearly lifted from a watchmaking lobbying group).
The main body of the book is of course a list of manufacturers and the most significant new launches / current models being sold. For each watch manufacturer the author(s) provide a brief company introduction, followed by the individual models, as well as the movements (in case these are designed in house).
This is obviously the main feature of the book but comes with some caveats. The coverage is by no means universal or complete and it appears that the author shows preferences to some brands over others. So long as you are aware of that and not looking for a complete overview (but are satisfied with a moderately comprehensive one), you should be fine here. There are some notable omissions (for instance some manufactures have no movements covered) and the company histories are more or less always given a positive twist (one can assume the PR departments of various watchmakers having had a significant hand in composing those parts).
The data provided includes all the essentials, from the movement used, to the complications / features, dial, case and strap / bracelet design and materials, dimensions (both movement and case), variations (if any), and a US market price. The latter means that some watchmakers, which are not present in the US market are not covered (although some others are included).
Following this comes a section on standard movements utilized by the manufacturers not making theirs in house (i.e. ETA) and a final section with an illustrated glossary. This is particularly useful for the novice watch enthusiast, as it will explain all the important components in sufficient detail to garner some elementary understanding (and the pictures help, too).
If you are hoping for commentary or critical analysis of the watches covered, the book will clearly disappoint, as this is not its focus. If, on the other hand, you prefer an overview of some significant new market entries / current collections of most watch manufacturers to come in a book format (as opposed to searching for the information on the net), this is a solid guide. It may have an advertorial twist in some of its components but definitely involved a lot of effort in putting together and provides a very decent (if not complete) overview of what is available on the current wristwatch market.
