Longlines admiral 5 star mechanism question

Hello,

I have beautiful longines admiral 5 star, and I’m wondering how can I change date. Inside is cal. 507 moving hands backwards don’t change day, there’s no second position of the crown. I was trying to pull it quite hard but without a result. Going to the first position works normally. Quickset 9-12 doesn’t change day or date.
Is there some kind of unique way of changing day and date or how does it work? Or maybe there’s something wrong with the mechanism.
I’m kindly asking for any advices thanks 😀

Yep. You push the crown in to quickset the date.

Pushing it from 0 position? There’s no room at all to do it, like in 1481 automatic omega movements, I tried also from 1st position pushing and moving backwards but it’s not working, hm I’m concerned what’s going on. Can anyone precise how this should look like exactly?

I've serviced a few of these 505 and 507 movements. You should be able to push the crown in from the 0 position (mainspring winding). When you release the crown the date clicks forwards. Sometimes the mechanism isn't working because you need to replace a (broken) spring.

Both day and date should also change when you move the hands over midnight. So if that doesn't work either then there is something wrong with the calendar works which needs looking at.

It’s interesting because I have also another longines only date option and it’s easily visible that crown has space to be pushed and quick set is working while the one I showed in the first post has no space at all. Crown is sitting in the case in position 0 and not a single mm space, it sits like a normal crown. First photo is date only with quickset workinh while the second photo shows day date without push possibility. Case seems to be exactly the same for both.

What’s wrong with day date one?

My guess is that a stem replacement went wrong somewhere in the past (stem cut too short).

hm, maybe but the other case got deeper cuts for crown to be pushed while the second one is like normal.

Have you checked the movement calibre inside? It may not be 507 but 503 which is also day-date but doesn't have the quick set function?

I don’t understand what happened here, all about this watch looks good.
without quickset i cannot adjust day. Or is there another way?

Does a cal 507 belong in that case reference?
