ETA 255.481-487 Caliber Service Manual Part 3
Service documentation for ETA calibers 255.481, 255.483, 255.485, and 255.487. Part 3 contains: assembly diagrams for the hand-setting mechanism and base movement with numbered parts lists; calendar mechanism assembly with parts in assembly order; electrical test procedures and positions; dial fitting and hand-setting instructions for models with day/month/date and moon-phase complications; and technical specifications for testing battery voltage, circuit impulses, and coil resistance.
Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
Once downloaded, you can use it right away and even print the pages you need, or use your smartphone in photo mode to translate into the language of your choice: Google Translate
