ETA SA V8

The V8 designation on ETA movements indicates Swiss manufacture, not a specific caliber number. These are quartz movements produced by ETA SA in Switzerland, with the actual caliber number etched separately on the movement. The V8 stamp serves as a country-of-origin marker and is often more legible than the caliber number itself, particularly on smaller movements, which has led to confusion in the watch community where the designation is sometimes mistakenly referenced as a caliber.
