If the movement matches with the case number you are all fine

Excluding any typo error which I doubt very much from Patek Philippe!
There are 2 possible reasons.
1. The movement was replaced with the same new old stock originally made in 'Date'
2. It was produced with a new old stock movement
So long the watch movement number matches the watch case number you are doing fine.
