Book The Repair of Pendulums

Only available in GERMAN

This book was published in 1977 by the Association of Technical Schools in Switzerland and is now available for the first time as a revised reprint.

The repair of the pendulum clocks is written by Eugène Jaquet (formerly Direct of the Geneva Watchmaking School) and Dante Gibertini (formerly technical director and teacher of the repair class of the Geneva Watchmaking School).

The defects that usually occur in all pendulum clocks and how to rectify them are dealt with in the same way as the precautions that must be taken when dismantling and setting up the clockwork.

Anyone who specializes in the repair of old and antique pendulum clocks will love this book as an instructive tool.

In addition, there are other pendulum clocks or clocks in the book, such as the English clocks. What was also explained in detail for the Pariserpendule also applies to a large extent to other large clocks anyway.

The deficiencies that usually occur in all Pendulen and their remedies are dealt with in detail, especially those in the Parisian Pendule
with final disc. The precautions to be taken when dismantling and erecting the pendulum are also described.
