When does the date jump over in a cal. 752?

Hey folks,

I've just received a beautiful example of a 166.032 from our very own @ConElPueblo , sporting a cal. 752 that runs very smoothly.

When going through the lengthy process of setting the day and the date, I noticed that the day disk jumps over at midnight, yet the date does so at exactly 5am. It's been a while since I last owned an Omega with a 752, so I was curious if any of you could tell me if it's designed to work this way (maybe for both functions not to interfere) or if it's an "issue" that I might have adressed by my watchmaker?

I'd like to point out, in all fairness, that this is not to criticize the seller in any way - he's as curious as I am, so this is for educational purposes only, not to re-negotiate or express any hard feelings.

Thanks a lot, looking forward to be enlightened!

They should change basically at the same time. This is something that can be adjusted if your watchmaker knows how.

Here is an example - before adjusting:

Thanks a lot @Archer
As always. 😀

I'll attest to the fact that both day and date can indeed flip over at midnight concurrently. A photo of mine just prior to snapping over crisply.

Very few people have ever accused me of being well adjusted. The validation OF gives me is priceless, lol.😉

Thanks for the feedback. Doesn’t worry me one bit - actually, I sympathize with that. To me, the new day starts when I’m done sleeping, not when the clock strikes midnight. Come to think of it, I might ask him to adjust the day disk to do the same. 😁

It's a simple adjustment of the day finger, shown below at the red arrow:
