The document presents specialized horological tools designed for use with precision watch calibers, particularly the ETA Valjoux 7750 movement, and a set of professional screwdrivers. It serves as a technical reference, providing multilingual descriptions (French, German, Spanish, and English) to ensure accessibility for a wide audience in the watchmaking and repair industry.

At the center of the document is the tool identified as 30081-EX-7750, an instrument specifically developed to adjust the eccentric screw of the ETA Valjoux 7750. The 7750 is one of the most respected and widely used chronograph movements in Swiss watchmaking, renowned for its robustness and reliability. However, servicing such a complex caliber requires accuracy, especially when fine-tuning components like the eccentric screw of the minute counter jumper. This tool provides that level of precision. It is a screwdriver with a blade adapted to fit and control the eccentric screw, allowing horologists to perform adjustments smoothly without risking damage to delicate movement parts. By tailoring the tool for the family of ETA Valjoux 7750 calibers, it ensures compatibility and reliability for professional watchmakers who frequently service or regulate chronographs.

The file also describes another product—30081-C-P05, a set of five Phillips screwdrivers. These tools are manufactured to high standards suitable for professional workshop use. The screwdrivers are constructed from stainless steel, ensuring durability and resistance to corrosion. Each is fitted with an ergonomic handle made from POM (polyoxymethylene), a synthetic self-lubricating material that enhances comfort during long periods of use. This choice of material also reduces friction, making the screwdrivers easier to handle and more efficient in workshop environments. The blades themselves are crafted from hardened stainless steel with a hardness rating of 53/55 HRC, providing both strength and longevity. The set includes screwdrivers in five different blade diameters: 1.20 mm, 1.50 mm, 2.00 mm, 2.50 mm, and 3.00 mm, covering a broad range of applications in watch servicing, from small component adjustments to more robust assembly tasks.

The multilingual structure of the document underscores its international relevance. Each product description is presented in French, German, Spanish, and English, reflecting the global nature of the watchmaking industry and the wide distribution of these tools. This approach not only aids comprehension across markets but also highlights the manufacturer’s intent to provide clear technical guidance to professionals worldwide.

From a functional perspective, the eccentric screw adjustment tool is essential for regulating chronographs with accuracy. The ETA Valjoux 7750 is used by numerous high-end watch brands, and its performance depends on precise regulation. Without a tool designed specifically for its eccentric screws, a watchmaker risks improper adjustments that can affect the reliability of the minute counter mechanism. By providing a blade tailored to the screw’s dimensions, this tool enables efficient, repeatable, and safe adjustments, reinforcing its value as a workshop essential.

On the other hand, the set of Phillips screwdrivers offers versatility and everyday utility. Unlike the highly specialized 7750 tool, these screwdrivers can be used across many different watch movements, cases, and components. Their hardened blades and ergonomic grips make them ideal for repeated professional use. The inclusion of multiple sizes ensures coverage of most standard applications in horology, making the set a comprehensive choice for both independent watchmakers and large service centers.

In summary, this document introduces two complementary products aimed at professional horologists. The 30081-EX-7750 eccentric adjustment tool represents specialization and precision, serving a specific function for one of the most important chronograph movements in Swiss watchmaking. Meanwhile, the 30081-C-P05 screwdriver set embodies versatility and durability, providing reliable performance in everyday watch repair and assembly tasks. Together, they highlight the manufacturer’s commitment to supplying high-quality, purpose-built instruments that meet the rigorous demands of the watchmaking industry.
