🔧 What it does & how to use

This is a comprehensive, interactive training and reference resource for anyone working on the ETA/Valjoux 7750 — the movement found (in this or closely related form) inside automatic chronographs from makers such as Breitling, Omega, Longines, IWC and Baume & Mercier. It's aimed at both professional watchmakers and keen amateurs who want a clear, visual walkthrough of the movement rather than a dry text manual, showing exactly which parts come off, in what order, and how the chronograph start/stop mechanism works.

• Load the guide: plug in the USB stick and open the interactive program on your computer.
• Disassembly: follow the step-by-step diagrams showing which parts to remove, and in which order.
• Rebuild: work back through the graphical sequence in reverse to reassemble the movement correctly.
• Lubrication: check the guide for where and which greases and oils are recommended at each point.
• Adjustments: use the included sections on functions and adjustment to fine-tune timing and the chronograph mechanism.
• Printing: open the supplied PDF/Adobe Acrobat files if you want hard copies of specific pages or diagrams.
