MK40 Date Change Question

[guinsburg]

Hello,

Any fellow owners can tell me if theirs also change the date between 3 and 4 AM?

May that be a sign of impending failure?

Should change near midnight. If it has always changed at this time, it indicates that whoever installed the hands did a very poor job..

My 3513.53 changes just after midnight.
