Movement swap question?

[panerai153]

I think someone answered this a while back, but i can't find the thread. Changing out a 2836-2 for a slow beat movement. Which will fit with the least amount of problems, 2846-2, or a 2873? Just got in a little 6538, and I want to transplant a slow beat movement for the fast beat.

Thanks

The 2846-2 is the simplest- hands fit, same size as a 2836-2.
