ETA 255.265/266 Assembly and Electrical Test Manual
Technical documentation for ETA calibers 255.265 and 255.266. Pages contain: assembly instructions for the hour-setting mechanism and basic movement with numbered part lists; calendar mechanism assembly with detailed exploded views; electrical test procedures with measurement points and control parameters for battery voltage, integrated circuit output, power consumption, coil resistance, and stop-lever function; hand-fitting height specifications and dial-seat elevation measurements for both calibers with technical cross-section diagrams.
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
