Vintage Chronomat parts availability?

[Drecian]

Hi guys,

I'm looking a picking up a late 1945 Chronomat 769 with the Venus 175movement.

The only thing is the balance wheel/staff will need replacement and the rest of the movement may need to be overhauled. Can parts still be sourced for the Venus 175 at realistic prices? The crystal and crown have been replaced with aftermarket items, so I'll be looking at replacing them sometime down the line too.

Thanks.

Jeff.
