Wristwatch Chronometers: Mechanical Precision Watches and Their Testing (Schiffer Book for Collectors)

Rating:
Summary: Interesting, but very carelessly prepared
Review: Although the book contains very interesting information on chronometer testing, there are literally hundreds of spelling errors. One wonders about the accuracy of the information when the book was assembled in such a careless fashion.

Rating:
Summary: Super reference book
Review: As an avid collector of chronometers, I recommend this work. It is a nicely done reference work with a listing of chronometer grade movements and how they were tested.
