My new vs movement. Date sits low, I may try to re-use the old sh datewheel. Or I might keep my eye open for an inexpensive gen
Sometimes dial feet from one factory don't line up exactly with a movement from a different factory. It's possible to move dial feet only slightly but with a 31xx, replacement dial feet that have bases on them are slightly problematic because there is no dial spacer to notch a little to offset the foot base thickness.
Another solution, which I have used on occasion:
Clip the dial feet, and sand the areas flush
Use 4 small blobs of epoxy in open areas of the date plate to anchor the dial. A dial adhered this way is easily removed with a razor when necessary.
This allows you to rotate the dial clockwise a few degrees, which can fix your date issue. Note that this will also improve your rehaut crown position and the relationship between the date window and the cyclops, both of which are off anti-clockwise. Ofc this changes the hands-to-dial relationship but it's not a factor here since your hands have to be reset anyway.
This dial rotation trick is not uncommon to use on reps that have movements connected to movement holders with screws (like a TC), or dial feet that are set into the movement holder (like a 2836 Day-Date). You can sometimes use this to advantage as described above.
