Blancpain triple calendar 6595 - how to set?

[_noah]

Just purchased my first nice watch - a Blancpain 6595 triple calendar from ~1995.

I have a terribly dumb question though, how does one set the day of the week, date, month, and moonphase?

I found an article after much Googling about newer triple calendars on Blancpain's website, but the four "pins" on mine don't move (and I don't want to force them).

Seeking advice for anyone who owns/has owned/knows this watch have some advice on how easy it should be to press the pins OR if I'm missing something obvious and the watch should only be set at certain times (e.g. only press the pins when the watch is at 12:00)?

OR if anyone has a pdf of this watch's owners manual, that would likely be helpful as well!

Thanks in advance!
