For the semi-instantaneous date mechanism in the 8800 and similar calibers, the tolerance is +/- 10 minutes of midnight.

And if it's over tolerance? What does it mean then? Does it mean a watch that changes 8 min earlier is less accurate than a one changes on the dot?
Also, can it be cause due to playing with mechanism and changing dates in the 'bad zone'?
Who has a jbb where he/she needs to know the correct date between 11.50 pm and 0.10 am or else somebody will die if it's wrong?
Answer to your second question is no.
Which part of the questions there were many in my comment

A watch less accurate if the date change doesn’t happen precisely on the second when the time registers 12:00 midnight? You really have no idea, do you! Relieve yourself of your anguish, and buy a digital watch. Digital timekeepers are not watches, they are computers.
