The black wheel is not the same as 7S26. I tried swapping them so I had to fix the teeth on the original gear.  The movement is now advancing the day/date. My question now is, did I screw this up by changing the day wheel or was this a factory defect? I'm tending towards factory defect and I guess it was my fault that I didnt try advancing it before I replaced the wheel. What would you guys do who have more experience with watches?

Altough there are two version of the black day/date driving wheel, you can't mix these up because one has a male pivot, and the other is female. Otherwise  I can't understand what are you talking about. When in doubt you can check my parts reference sheet:https://docs.google.com/spreadsheets/d/e/2PACX-1vRN2UULQKTfKmhRStZhDdIOIQrqd6sPB-g6x2SKyQQjOvTBjG_7TQXQhAT4f1WqAX5QAPkIimi-3jqd/pubhtml

The c-clip has pinged away because it wasn't fully seated, probably due to the day disc not being installed correctly. Just like other systems the calendar work is delicate, you need to be sure that everything is square and seated before moving on.

What I was referring to is the black wheel. I tried to replace the one with the damaged teeth from the nh36 mvmt with one from the 7S26 and found that the pivot point underneath is different so I tried to straighten the teeth which worked for a few date changes but eventually it gave out. When I took off the c clip to check if the black wheel was turning that was when it pinged away but the ones from the 7s26 work.

      Any tips to correct a sloppy error?

      By Geotex · Posted

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.

      Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
