BY CHARLES EDGAR FRITTS (EXCELSIOR),
Author of "Practical Hints on Watch Repairing," "Practical Treatise on
Balance Spring," "Electricity and Magnetism for Watchmakers," etc., etc.
This well-known work is now recognized as the standard authority on the
adjustments and kindred subjects, both here and in England. It contains
an exhaustive consideration of the various theories proposed, the
mechanical principles on which the adjustments are based, and the
different methods followed in actual practice, giving all that is
publicly known in the trade, with a large amount of entirely new
practical matter not to be found elsewhere, obtained from the best
manufacturers and workmen, as well as from the author's own studies and
experiences.
