🔧 What it does & how to use

This is a reference library for anyone servicing or repairing Valjoux chronograph movements — useful for both hobbyist watchmakers and professionals working on these calibres. The 7750 documentation is a fully graphic, step-by-step disassembly and assembly guide with oiling points marked throughout, together with a separate PDF explaining the movement's functions and how to operate it. The 13, 23, 69, 71, 77 and 84 guides are each around 50-60 pages, covering parts diagrams, disassembly, adjusting and oiling in full detail. The 14 bestfit catalogue images give parts identification for these movements. Everything is supplied as separate PDF files on the USB stick, so you only need to print the calibre you're actually working on.

• Check parts: refer to the bestfit catalogue images to confirm part numbers
• Print what you need: each calibre is a separate file, so print only the one you're working on
