The ETA caliber 2840 is a a vintage automatic watch movement that was meant to be an economy version of the 2800 family of movements, with some similarities to the framework of the famous 2824-2.
This caliber is found exclusively in Swatch watches from the 1990s (since circa 1991), which is why official technical documentation appears to be non-existent.
You may see this calibre described as being the no-date version of the 2842, however, there are 2842 movements without a date as well.
