    Book review
    From: Alexandre Eremenko
    Date: 2012 Nov 12, 16:10 -0500

    Today I received the new book by Bill Morris,
    The Mariner's Chronometer. Structure, function, maintenance
    and history, 167 pages, large format paperback.
    It can be bought through amazon for US$38.75, GBP25.00 or Eu29.00.
    I already read this book in manuscript form, so I can describe it now.
    What I found especially valuable in the book, is that it contains
    an explanation, how detent escapment works, which I could understand.
    (No other book that I read before had this property:-)
    Table of contents: 1. Introduction, 2. Principles of chronometer
    mechanism, 3. Disassembly, 4. Cleaning and oiling, 5. Reassembly
    6. Regulating and rating, 7. Care, 8. A brief history.
    Appendices: 1. Detent adjustment, 2. Break-curcuit chronometers,
    3. Movement holder.
    Bibliography, Index.
    The book is very reachly illustrated with color photos and
    line drawings, illustrations are of very good quality.
    I have to say that I never dared to disassemble my own chronometer,
    (and I am not sure that I ever will; it works fine:-) but nevertheless
    I read the whole book with a great interest.
    Even the small chapter 8 is packed with information which
    cannot be found in other books that I know.
    I strongly recommend it to all interested in clocks, watches
    and history of navigation. And of course it is a must have for
    those who collect chronometers.
