New date wheel not lining up... Sort of... NH36

So I'm in the midst of my first ground up build and am (unsurprisingly) having some issues. I swapped the stock white day/date wheels from my NH36 movements for black ones to better compliment my dial. I then tested the functionality before putting the dial on and all seemed to me working correctly, however once the dial was on I discovered an issue. The date wheel isn't quite lining up correctly. Here's the weird part: when I use the quick set function they line up fine. It's when I set them via turning the hands (which I was doing in order to determine 12am so I could install my hand set) that the date clicks in place a little high. Also if I have the date set and lined up correctly via the quick set function and pull the stem out to the hacking position the date wheel moves and misaligns. Any ideas of why and how to fix it? Thanks!

Have you greased where it makes contact with the rest of the operating mechanism. Make sure when you screw the dial tight or it might have clips to hold the dial that it isn't fouling the works up. Check the dial feet to make sure they are not bent. This will sound silly to you, have you got all the parts in correctly. Did you replace any thing other then what you have said.

Seiko 5 dials don't have screws nor clips. They normally align very precisely thanks to a rising of the plastic casing ring.

Normally, the most common reason for calendar misalignment is due to using the wrong parts. The day disc has come with alignments for crown at 3h or 4h, and the date ring has two types of alignment depending on the mov.t version they were made for. All that is in my document below:

https://docs.google.com/spreadsheets/d/e/2PACX-1vRN2UULQKTfKmhRStZhDdIOIQrqd6sPB-g6x2SKyQQjOvTBjG_7TQXQhAT4f1WqAX5QAPkIimi-3jqd/pubhtml

That being said in the OP case it seems something has not been installed correctly so after the P/N check above attention must be given to  how the jumper engage to the date ring.

Thanks! I think that jumper spring may be the culprit. They are the correct day/date wheels and I haven't replaced anything except what I said in the OP. It is also possible that one of the dial feet may be bent but the dail looks to be pretty well aligned to me...

      @Klassiker the AM220 is a good start, there's hints of this escape wheel cock and bridge shapes in the other larger AM movements on Ranfft as well

      Balance not rotating anymore

      By Poljot · Posted

      You did not tell what was that "extra" screw for. I would do the following: - release the mainspring - remove balance bridge - remove pallet fork - rotate train wheels manually to confirm they move freely. If they don't - find out why. Once that is resolved or confirmed, next stem - replace the pallet fork, wind the main spring just few rotations, push the pallet fork gently to see if mainspring energy is being transferred and wheels are moving - just take a closer look at both pivots of the balance staff. Again, gently and without pulling too hard - check both pivot, top and bottom. You may have bent one while removing the balance bridge several times (i hope you did not). - with the mainspring wound, replace the balance bridge. Often balance would self-adjust (impulse jewel / fork) and start moving. Gently replace the balance bridge screw. Good luck!

      Balance not rotating anymore

      By Negot8or · Posted

      Valjoux 23/72 ... hadn’t been worked on in a long time.  Tore it down, cleaned it, reassembled - everything worked ... until I realized I left out a screw. Tore it back down, installed everything fully this time.  Balance wouldn’t rotate.  Gears seemed like they were seized. Tore it back down, spent a LOT of time on each assembly step, ensuring everything spun freely.  Installed the palate fork - flicked back and forth as appropriate.  Installed balance as the last step.  No rotation.  Spins freely when “encouraged”, but it doesn’t continue. I pulled it out.  Confirmed that the hairspring isn’t kinked.  Jewels look fine (no cracks or chips).  I don’t have the means to check if the balance staff is bent, but the balance seems level and when I encourage some rotation, I don’t see any wobble. Any thoughts on what to check next? Thanks!

      Opening clock mainspring barrel

      By HectorLooi · Posted

      I installed the spring back inside the barrel yesterday and checked it this morning. The copper wire band is still holding. But now I have a new problem with this clock. The strike mainspring is going to break at the eye. Is it possible to cut off the end and cut a new eye or should the spring be replaced?
