I have for sale, from my own personal collection, NOS Vintage Omega Calibre 563 Movement Parts. Please see the dropdown list for all of the parts available. Please note that some parts (where indicated by "x1" - such as stems, case clamps and various springs) will come from a multipack so you may just receive the part not the original Omega packaging. 

With regards to the 563-1568 Date Corrector Yoke part - I have these in both perfect condition and others which have a very light coating of rust - see the last picture for an example of these ones. The rust is very minimal and will easily clean off with oil or similar.

I have had these items for many years but I now have no need for them any longer. They are all new old stock that have never been used.

Please feel free to ask any questions.
