I have been a watch hobbyist for 25 years. 5 years ago, I opened my watch repair shop in the Durham, North Carolina area and also via mail-order. My website is TheWatchFixer.com .  The watch in question is a customer's watch and is currently disassembled in a parts tray. It's a 1975 Hamilton Clermont model. I am attaching a photo of what it would look like if assembled.

Can the owner not tell you if it has always had this day/date change-over discrepancy  ?

That's an excellent question! I didn't pick up on it in my initial evaluation, but the owner is convinced that the calendar worked just fine when he brought it to me. So, because I failed to identify any calendar issue when I took it in, the only thing I can do is make it right on my own time and dime. I am just not understanding what I may have done to make it malfunction as it is. It's a head scratcher for sure...

If one of the fingers has rotated 180Deg then it must at some time have
been loose so can't understand why it's not free to move now?

are the push fingers attached to the wheel or part of it ?

If they are attached has one come free and possibly jammed itself in a new position ?

I think one is attached to the wheel and the other side is then attached to it.

I'll have a closer look tonight when I get home.

I want to provide a follow-up to this most interesting issue. I found a seller in Mannheim, Germany who had the calendar wheel (that I strongly suspected was bad or wrong) and I purchased it from them. It came in today, and it is the exact opposite orientation of the one I had. I installed it and the day and the date now change over in exact unison with each other. It's a thing of beauty! I have no clue about the bad calendar wheel. I don't see how it could have been re-arranged in any way, as it appears to be a riveted part. I can only suspect that the part I had was not correct for the movement? But yet, my customer says it worked just fine when it was brought to me? So, the only take-away I can share here is that if you buy watches or take in watches for repair, always do a thorough functional triage of the watch prior to opening it. It's important to see how it works before trying to fix anything, and may help with your sanity when you run into a problem like this. In conclusion, it was indeed a bad part, the watch is working like new, and you can cue the "Twilight Zone" music. Thanks to everyone for your assistance.
