"A how-to guide to diagnosing and correcting faults in clocks, antique and modern." -- Cover, p. [4].

Here is a unique book. It describes the theories and processes of repairing and adjusting the modern watch in precise and meticulous detail: a thing which has never been done so completely before in the many books on the same subject. As a text book it is a revelation. Taking nothing for granted, except the ability to read and comprehend a simple description of mechanical processes, de Carle takes his reader through every stage and every operation of watch repairing ...and to deal with them thoroughly is quite a programme - it takes 300 pages containing 24 chapters, two appendices and 553 illustrations. The fine draughtsmanship and accurate technical detail of the illustrations set a new standard. Practical Watch Repairing can justifiably claim to be the best illustrated book on practical horology yet issued, and one of the best of its kind on any subject. The publication of the book marks the beginning of a new epoch in the study of the mechanics of horology.

Why does an Anniversary Clock stop Working? Most likely, it is because the suspension spring is broken. I will teach you how to replace it.

Often, the works are dirty, need oiling, or most likely both. When the clock stops, think of it as "the oil light is on." It's a "cry for help." Without oil, the metal parts grind on each other, causing severe wear and damage. Oil also attracts dust, making the oil "gummy" and adding drag to its operation until it can no longer overcome the friction. If a clock is oiled regularly [every three to five years], chances are you will only ever need to re-oil your clock. If the clock is allowed to run until it stops, the only sure way to service it is to remove the works from its case, dismantle the parts, clean, service, and put the movement back together with fresh oil and correct adjustment.
