ETA caliber 256.041 is a 2 hand Swiss made quartz movement with 6 jewels. Official documentation for this movement was found with dates from 2009. This caliber 256.041 is currently discontinued by ETA. The replacement is caliber E61.041. You may also be able to use ETA caliber 256.031, but this should be confirmed first. If you just need the electric module, the part number is 4000.

5 or 6 Jewels, Date or No Date:

Official ETA tech sheets list this caliber as having 6 jewels with a calendar (date) complication, however, we have come across movements signed with the same caliber number, but having 5 jewels (for example: the picture posted by Fabio in the comments below). This could be an older version of the movement, but it could also have something to do with date/no date. The 5 jewel versions found were hours and minutes only and without a date. Please comment below if you have a 5 or 6 jewels movements and whether your watch has a date or not.

Why some of calibers 256.041 have 5 jewels against 6 jewels in this data sheet?

As answer to the question:

I saw this Longines Presence with caliber 256.041, wich is about 1990-1999. The model of Longines is 7229 and in fact how the writer said it doesn´t have date. Here is the picture:
