ETA 201.001 Technical Documentation 4¼ Inch
Technical documentation for ETA 201.001 watch movement. Includes dimensional specifications (4¼ inches, Ø 9.90 mm, height 2.25 mm), mechanical drawings of the movement from multiple angles showing gear train and internal components, hand-fitting specifications for 4 hand lengths (1.04 to 2.54 mm), interchangeability charts with reference numbers for ETA 101.001 and 201.001 calibers, and electrical testing procedures with circuit diagrams and measurement specifications for battery voltage, motor current, movement consumption, 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
