Per this picture, it is running at +6 seconds per day. Whilst this is not ‘good’ for a COSC certified chronometer, I think it is acceptable given that the watch is not worn every day.
I have had this date setting problem occur in other watches with ETA movements before. To help avoid this happening to your watch, two of the things you should do are:
- Never change the date manually when the hour hand is about the 9 and 3 mark Adjusting the date with the quick-set can damage the movement in this position.
- Never wind the hands back beyond the 12-midnight position, this can damage the movement.
