I did not even know this was a thing till a week or so ago(non-quickset).
My grandma had her late brothers day/date on the other day and I pointed out that it was incorrect.
She told me it is so hard to set so she does not bother.
I told her "No way, le t me see it.............
...........
...........
Yeah I don't know". Lol.
My Hamilton is the only day/date I have ever used and I just assumed that pulling out the crown to different positions was the standard for everything.
My grandpa (her husband) has a newer day/date that has quickset though. So she taught me something hah.
