A masterpiece of technical expertise

The mechanical watch has a long history dating back to the 15th century. Since then, watches have played a central role as precise timekeepers and as an expression of technical mastery. “The Wristwatch and Pocket Watch in Repair” is devoted in depth to the fundamentals of mechanical watches and explains the function and repair of the main components, such as the mainspring barrel, gear train, escapement, and dial. With precise instructions and a wealth of illustrations, this book guides the reader step by step through the repair processes – from the initial work on the case to the complete disassembly and restoration of the movement.

A detailed look inside the book

The book is structured into a wide range of chapters covering all essential aspects of watch repair. The authors have ensured that readers can master different levels of repair according to their skills and experience. Each chapter contains practice-oriented instructions that expand both the understanding of watch technology and practical skills.

1. Tips and fundamentals of watch repair
The first chapter provides a sound introduction to the most important tools and basic techniques of watch repair. It explains how to set up an optimal workstation, which specialised tools are required, and how cleanliness and order help to avoid errors. The importance of precision and patience is emphasised, as these qualities are crucial to the success of any watch repair.

2. Watch straps: replacement and care
Whether leather, fabric, synthetic material, or metal – watch straps are not only functional but also aesthetic components of a watch. This chapter covers everything important about replacing and caring for watch straps. Readers learn how to select the appropriate strap, fit it correctly, and ensure it withstands everyday wear. The use of specialised tools such as spring bar tools is described in detail.

3. The case: cleaning and repair
The watch case protects the movement and defines the external appearance of the watch. In this chapter, readers learn how to clean, polish, and, if necessary, repair cases made of different materials – whether stainless steel, gold, or synthetic materials. The handling of sensitive components such as the winding crown or the crystal is also explained in detail.

4. Removing the movement: step-by-step instructions
This central chapter focuses on removing and dismantling the movement. Readers are guided step by step through the process of safely removing the movement from the case. Particular attention is paid to the various systems used in mechanical watches and the techniques required to dismantle the movement without damage.

5. The winding crown and its function
The winding crown is one of the most frequently used parts of a watch. This chapter shows in detail how to dismantle, clean, and replace the crown. In addition, the correct care of the crown is described to ensure its functionality over many years.

6. Polishing and cleaning: cases, hands, and dials
Polishing and cleaning are essential steps in restoring a watch to its original appearance. The book explains the best methods for caring for cases, hands, and dials, removing scratches, and eliminating discolouration. Readers learn how to apply different polishing materials and techniques to various watch materials.

7. Cleaning and reassembly of the movement
The movement is the heart of every mechanical watch, and its care requires particular attention. In this chapter, readers learn the correct techniques for cleaning movements, whether by machine or manually. It then describes in detail how to reassemble the movement and oil it correctly to ensure smooth operation.

8. Escapement and balance: adjustment and repair
The escapement and balance are critical elements of a mechanical watch. This chapter deals extensively with the adjustment and repair of these important components. From the classic lever escapement to the pin-pallet escapement and the cylinder escapement – all common systems are discussed and repair techniques are explained.

9. Water resistance testing and final inspection
Mechanical watches often have to withstand high levels of stress, particularly with regard to water resistance. The book describes the most important methods for checking and ensuring water resistance. In addition, the chapter provides useful tips for final inspection to ensure that all repairs have been carried out correctly and that the watch functions perfectly.

10. Regulation using the timing machine
A chapter of particular interest to watchmakers and ambitious hobbyists. Readers learn how to check and optimise the rate accuracy of a watch using a timing machine. The authors describe the use of the timing machine and provide valuable guidance on correct regulation.
