Submariner Date Advance at 0400?

[mclain777]

I purchased my 116610LN in early 2015, brand new at an AD. Not my favorite watch and I do not wear it too often. I recently noticed the date advances at 0400 hours. Might be a dumb question, is this normal? When I use the quick set function, the date flips at midnight.

Pursuant to the card that came with the watch, there is (was) a two year warranty. Guess I am out of luck for an in-warranty service. Should I just live with it or bite the bullet and have the watch serviced? Cosmetically it is in very nice condition and it keeps reasonably good time.
