·I purchased a constellation from an auction that has a "561" movement in it.
I have been working on servicing and restoring it, but have encountered at this point numerous strange things.
I wanted to ask if anyone knows if its possible that a 550-1000 would be swapped out for a 563-1000 main plate during a legitimate service?
This movement has a 563 main plate based on the lower incabloc setting, and also had a strange mishmash of the expected and 563 keyless works parts. So I am really starting to suspect a franken-movement.
Did i get a 565/3 with 561 bridges swapped in to make it look like a chronometer?
Is there anything visually identifiable for a chronometer balance? Or would I need to get some additional tools for checking the poise of this balance?
I am trying to determine of its worth it to sink a bit more into this movement to get it running again, or if I write this one off as a nice case and dial, turn it into a donor and look for a 564 donor to swap in wholesale.
At this point i need a winding wheel and a lower incabloc spring to get this running again, both of which are proving to be surprisingly difficult for me to obtain at this point.
