The
recent completion of the third serial gave us the opportunity to
republish in book form, and the present volume is the result. We present
it to the trade and students of horology happy in the knowledge that its
contents have already received their approval. An interesting addition
to the book is the illustrated story of the escapements, from the first
crude conceptions to their present perfection.

CHAPTER I.
THE DETACHED LEVER ESCAPEMENT.

In this treatise we do not propose to go into the history of this
escapement and give a long dissertation on its origin and evolution, but
shall confine ourselves strictly to the designing and construction as
employed in our best watches.
