I have found that (with the train of wheels, at least), gen parts will work in a clone 2824, but don't try to put clone parts in a gen mvmnt...that way leads to madness.
A while back, I had a gold gen Bulova branded 2824-2, and after cleaning and rebuilding, could not get it to wind, no matter what I did with or replaced in the keyless works. Teeth were slipping, and it wasn't the mn sprng brl. After letting it stew for a few months, I finally realized I had been using a clone stem, which somehow got swapped.
...even though it looks IDENTICAL to a gen ETA stem. Minisclue tolerances exist for reasons.
